Options

Please Note – Factory Set Open/Close Timing: Multiple factors can influence the valve’s standard open/close time, including media type, viscosity, pressure (psi), temperature, and more. On average, the valves require approximately 0.5 seconds to fully open or close once energized or de-energized.

• 81 - Slow close
• 84 - Quick close
• 76 - Spring-loaded pilot for vertical mounting (recommended only for valves up to 1" NPT)

Mounting and Service

Installation: Install in HORIZONTAL pipe with COIL ASSEMBLY on TOP AND VERTICAL with FLOW ARROW or IN AND OUT markings in the proper direction. ALL PIPING should be blown clear before installation, and a 40 mesh STRAINER should be installed ahead of the valve. STEAM LINES should be properly TRAPPED at the valve inlet. PIPE DOPE is NOT recommended, but if used, should not be applied to the VALVE BODY. Apply sparingly to the pipe threads only. J.D. Gould Company recommends Teflon™ tape for all connections. PIPING should be properly aligned and supported to avoid strain on the valve body. The VALVE BODY should not be held in a VISE except across the pipe ends. Use a PIPE VISE or WRENCH on the pipe and a WRENCH on the HEX PIPE ENDS. DO NOT use the COIL ASSEMBLY for a LEVER to tighten piping.

Maintenance: Close the supply SHUT OFF VALVE and ENERGIZE the SOLENOID VALVE to de-pressurize the inlet supply line. DISCONNECT ELECTRICAL POWER before removing the COIL ASSEMBLY. The COIL will overheat and burn out if left ENERGIZED without the entire SOLENOID ASSEMBLY in place. Since OCCASIONAL INSPECTION AND CLEANING is desirable, be sure to add the valves to your scheduled maintenance program. Flowing media and cycle rate will determine the desired interval between inspections. Removing the BONNET exposes the internal parts of the valve. It is not necessary to remove the VALVE BODY from the line for inspection or repairs. Valve parts may be cleaned in commercial products such as Lime-Away® or CLR™ to remove mineral deposits. Be sure any cleaning solution is compatible with BOTH the metallic and non-metallic (seats & seals) components. Parts should be rinsed thoroughly in clean running water before re-assembly.
