Warning: Disconnect electrical power and depressurize system before servicing. DISASSEMBLY INSTRUCTIONS PARKER: Unscrew nut on top of coil assembly. Remove spring washer and coil assembly. Caution: If the sleeve assembly does not have a hex style flange, do not use a pipe wrench directly on the sleeve; use the enclosed wrench nut to remove the sleeve assembly. Slide enclosed wrench nut over sleeve tube. Mate wrench nut to sleeve flange and turn wrench nut with appropriate wrench. The plunger, return spring, and flange seal may now be removed. Remove (4) cover screws. If cover cannot be easily lifted off of body, laterally tap cover or gently pry cover from body with a screwdriver. Care must be taken to not damage diaphragm cover, or body. Diaphragm return spring(s), diaphragm assembly, and O-rings can now be removed. ASCO: Gently pry off red plastic cap. Firmly press on green solenoid coil and slide metal data plate to release and remove solenoid coil. Remove (4) solenoid base screws. Remove solenoid base, core spring, core assembly, diaphragm spring, diaphragm assembly and body gasket from valve body. All Parts are now accessible for cleaning or replacement. If parts are worn or damaged, install a complete ASCO Rebuild Kit. REASSEMBLY INSTRUCTIONS PARKER: Refer to exploded view drawing for proper valve. Parts must be replaced in order shown. Diaphragm bolt and flow holes in cover must line up with bolt and flow holes in body. Tighten cover screws to 65-85 in-lbs for ¾” NPT valves and 110-150 in-lbs for 1” NPT valves. Install plunger and spring into sleeve. Tighten sleeve assembly to 130-150 in-lbs, again using supplied wrench nut. Slide coil assembly over sleeve and reinstall spring washer and nut. Tighten nut to 43-53 in-lbs. Pressurize system and check for leaks and functionality. ASCO: Lubricate body gasket and solenoid base gasket with DOW CORNING 200 Fluid lubricate or an equivalent high-grade silicone fluid. Replace body gasket and diaphragm assembly. Note: Position diaphragm bleed hole approximately 45˚ from valve outlet. Position large end of diaphragm spring into diaphragm cup. Install wide (open) end of core spring in core assembly first, closed end protrudes from top of core assembly. Position core assembly with core spring and solenoid base sub-assembly (integral with bonnet) over diaphragm spring and diaphragm assembly. Install bonnet screws and hand thread screws as far as possible, then torque bonnet screws in a crisscross manner to 95 10 in-lbs [10,7 1,1 Nm]. Install solenoid base gasket, core assembly with core spring and solenoid base sub-assembly. Torque solenoid base sub-assembly to 175 25 in-lbs [19,8 2,8 Nm]. 1-800-Midmark www.midmark.com Style A
