Coil Replacement

WARNING: Turn off electrical power supply.

1.Disconnect coil lead wires and green grounding wire if present.

2.Remove retaining clip, nameplate and housing.

WARNING: When metal retaining clip disengages, it will spring upward.

3.Slip spring washer and coil off the solenoid base subassembly.

4.Coil is now accessible for replacement. Reassemble in reverse order of disassembly. Use Solenoid Valve Exploded View Drawing for identification and placement of parts.

CAUTION: Solenoid must be fully reassembled because the housing and internal parts complete the magnetic circuit.

Valve Disassembly

WARNING: Depressurize valve and turn off electrical power supply.

1.Disassemble valve in an orderly fashion. Use exploded view for identification and placement of parts.

2.If necessary, disconnect coil lead wires, grounding wire (if present), and rigid conduit from solenoid housing,

3.Remove retaining clip and slip the entire solenoid enclosure off the solenoid base sub- assembly.

WARNING: When metal retaining clip disengages, it will spring upward,

4.Unscrew solenoid base sub-assembly and remove core assembly, core spring, and solenoid base gasket.

5.Remove bonnet screws, valve bonnet, piston assembly, lip seal, support, inner and outer body gaskets.

6.All parts are now accessible to clean or replace; Replace worn or damaged parts. However, for best results, replace all parts as supplied with an Rebuild Kit.

Valve Reassembly

1.Reassemble in reverse order of disassembly. Use exploded view for identification and placement of parts.

2.Lubricate all gaskets with DOW CORNING 111® Compound lubricant or an equivalent high-grade silicone grease.

3.Position support and inner and outer body gaskets in valve body.

4.Position lip seal, flanged end up, onto piston assembly. Install piston assembly with lip seal into support in valve body cavity.

5.Replace valve bonnet and bonnet screws. Torque bonnet screws in a crisscross manner to 95 ±10 inch-pounds (10,7 ±1,1 newton- meters).

6.Replace solenoid base gasket, core assembly, and solenoid base sub-assembly. Torque solenoid base sub-assembly to 175

±25 inch-pounds (19,8 ±2,8 newton-meters).

7.Replace solenoid enclosure and retaining clip.

8.Restore line pressure and electrical power supply to valve.

9.After maintenance is completed, operate the valve a few times to be sure of proper opening and closing.
