INSTALLATION AND MAINTENANCE INSTRUCTIONS

instructions

Compatibility

The ABZ Figures 090, 929, 909, and 919 valves can be used with all ANSI 125/150 pund flat or raised face type flanges. The seat face design eliminates the need for additional gaskets. Heavy wall pipe, lined pipe and flanges must meet minimum inside diameter requirements of dimension "E" to permit clearance of disc.

Installation

The ABZ valve is non-directional and is suitable for flow control in either direction. For optimum results in slurry applications, position the valve with stem horizontal and lower edge of disc open to downstream side. For installation between existing ANSI flanges, ensure that flanges are sufficiently spread to prevent contact of seat face with flange. Contact of seat face will result in damage or distortion. For applications using ANSI welded flanges, first place the disc in nearly closed position. Center each flange bore to the valve face bore, and install bolting through flanges and valve to align the joint with pipe. With all aligned, tack weld flanges to the pipe. Remove bolting and valve assembly prior to finish welding. Do not perform finish weld with valve assembly installed between the flanges. Serious damage to valve seat area will result. Allow weld to cool proir to installation of valve.

Installation Instructions

The sealing edge of disc is lined up with stem flats or keyway. Rotate stem clockwise to to place disc at least 3/8-inch inside of body face surface (as shown in Fig. 1). Spread flanges and center valve bodybetween them. Install as many attching bolts as possible. Rotate valve disc to the fully open position (Fig. 1 "C"). While maintaining valve-to-flange alignment, remove flange spreading tool slowly and carefully. Tighten flange bolting finger tight, then slowly close the valve disc (clockwise direction) while checking for proper clearance. Again position valve disc fully open (Fig. 1 "C") and cross-tighten all bolting to specified torque value. After all bolts are fully tightened, once again check for proper clearance of valve disc. The valve is ready for service. No lubrication or maintenance should be required other then the installation of the valve operator.

Disassembly of valve

The first step is to place the valve disc in the fully open valve stem. Next, remove the actuator or operator from valve stem. Remove attaching screws, then remove lower portion of valve body. Remove the disc/stem/seat assembly from the upper portion of the valve body. To remove the disc/stem assembly from the seat, deform seat into an oval shape sufficient to free the short end of stem from the seat bore. To completely free the disc/stem assembly from the seat, withdraw long end of stem using a twisting motion. Remove packing and bushing from stem. Discard worn or damaged parts that are to be replaced.

Assembly of Valve

Prior to assembly, clean all reusable parts and inspect for wear and damage. To facilitate assembly, lubricate parts with a good food grade lubricant (if used in food or sanitary service). First, insert long end of disc/stem into seat bore completely using a twisting motion. Deform the seat into an oval shape sufficient to allow insertion of short end of disc/stem assembly into remaining seat bore. Valve disc must be in open position to accomplish this procedure. Install disc/stem/seat assembly into valve body upper half, then install packing and bushing on stem. Install the valve body lower half, making sure that all components are properly aligned. Secure valve body halves together with screws and tighten securely.

For optimum results in slurry applications, position the valve with stem horizontal and lower edge of disc open to downstream side. For installation between existing ANSI flanges, ensure that flanges are sufficiently spread to prevent contact of seat face with flange. Contact of seat face will result in damage or distortion. For applications using ANSI welded flanges, first place the disc in nearly closed position. Center each flange bore to the valve face bore, and install bolting through flanges and valve to align the joint with pipe. With all aligned, tack weld flanges to the pipe. Remove bolting and valve assembly prior to finish welding. Do not perform finish weld with valve assembly installed between the flanges. Serious damage to valve seat area will result. Allow weld to cool proir to installation of valve.

Installation Instructions

The sealing edge of disc is lined up with stem flats or keyway. Rotate stem clockwise to to place disc at least 3/8-inch inside of body face surface (as shown in Fig. 1). Spread flanges and center valve bodybetween them. Install as many attching bolts as possible. Rotate valve disc to the fully open position (Fig. 1 "C"). While maintaining valve-to-flange alignment, remove flange spreading tool slowly and carefully. Tighten flange bolting finger tight, then slowly close the valve disc (clockwise direction) while checking for proper clearance. Again position valve disc fully open (Fig. 1 "C") andcroos-tighten all bolting to specified torque value. After all bolts are fully tightened, once again check for proper clearance of valve disc. The valve is ready for service. No lubrication or maintenance should be required other then the installation of the valve operator.

Valve Repair

The ABZ butterfly valve can be field repaired. Replacement of parts requires that the valve be removed from installed position. To facilitate removal, place the valve disc in the nearly closed position, loosen and remove the attching bolting, and finally spread the flanges to prevent damage to sealing surface of valve seat. Remove valve from between mating flanges.

Disassembly of Valve

The first step is to place the valve disc in nearly closed position. Next, remove the actuator or operator from valve stem. Remove bolts and O-rings which secure the valve disc to the stem. Withdraw stem assembly with packing and bushing to from the valve body. Remove bushing and packing from stem.

Assembly of Valve

Prior to assembly, clean all reusable parts and inspect for wear and damage. To facilitate assembly, lubricate parts with a good food grade lubricant (if used in food or sanitary service). First, insert seat assembly into valve body. Next, place valve disc inside valve seat assembly (stem attachment holes in disc up or closest to seat bore through which stem will be inserted). Insertt stem assembly into valve body and valve disc. Align with mating holes in valve disc and secue disc to stem with two bolts (O-rings placed under each bolt head). Install packing and bushing on stem, then tighten blots which secure valve disc to stem.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Compatibility

The ABZ Figures 090, 929, 909, and 919 valves can be used with all ANSI 125/150 pund flat or raised face type flanges. The seat face design eliminates the need for additional gaskets. Heavy wall pipe, lined pipe and flanges must meet minimum inside diameter requirements of dimension "E" to permit clearance of disc.

Installation

The ABZ valve is non-directional and is suitable for flow control in either direction. For optimum results in slurry applications, position the valve with stem horizontal and lower edge of disc open to downstream side. For installation between existing ANSI flanges, ensure that flanges are sufficiently spread to prevent contact of seat face with flange. Contact of seat face will result in damage or distortion. For applications using ANSI welded flanges, first place the disc in nearly closed position. Center each flange bore to the valve face bore, and install bolting through flanges and valve to align the joint with pipe. With all aligned, tack weld flanges to the pipe. Remove bolting and valve assembly prior to finish welding. Do not perform finish weld with valve assembly installed between the flanges. Serious damage to valve seat area will result. Allow weld to cool proir to installation of valve.

Installation Instructions

The sealing edge of disc is lined up with stem flats or keyway. Rotate stem clockwise to to place disc at least 3/8-inch inside of body face surface (as shown in Fig. 1). Spread flanges and center valve bodybetween them. Install as many attching bolts as possible. Rotate valve disc to the fully open position (Fig. 1 "C"). While maintaining valve-to-flange alignment, remove flange spreading tool slowly and carefully. Tighten flange bolting finger tight, then slowly close the valve disc (clockwise direction) while checking for proper clearance. Again position valve disc fully open (Fig. 1 "C") and cross-tighten all bolting to specified torque value. After all bolts are fully tightened, once again check for proper clearance of valve disc. The valve is ready for service. No lubrication or maintenance should be required other then the installation of the valve operator.

Disassembly of Valve

The first step is to place the valve disc in the fully open valve stem. Next, remove the actuator or operator from valve stem. Remove attaching screws, then remove lower portion of valve body. Remove the disc/stem/seat assembly from the upper portion of the valve body. To remove the disc/stem assembly from the seat, deform seat into an oval shape sufficient to free the short end of stem from the seat bore. To completely free the disc/stem assembly from the seat, withdraw long end of stem using a twisting motion. Remove packing and bushing from stem. Discard worn or damaged parts that are to be replaced.

Assembly of Valve

Prior to assembly, clean all reusable parts and inspect for wear and damage. To facilitate assembly, lubricate parts with a good food grade lubricant (if used in food or sanitary service). First, insert long end of disc/stem into seat bore completely using a twisting motion. Deform the seat into an oval shape sufficient to allow insertion of short end of disc/stem assembly into remaining seat bore. Valve disc must be in open position to accomplish this procedure. Install disc/stem/seat assembly into valve body upper half, then install packing and bushing on stem. Install the valve body lower half, making sure that all components are properly aligned. Secure valve body halves together with screws and tighten securely.
