Parker 70564 Solenoid Valve

The Parker 70564 Solenoid Valve, also identified by the GP457 model number, is a high-performance 1/2 inch NPT solenoid valve specifically engineered for saturated steam service. This normally closed solenoid valve features a rugged brass body and a stainless steel seat insert to withstand high-temperature environments up to 300°F. Designed with an ethylene propylene (EPT) diaphragm and specialized seals, it provides reliable flow control with a 3.35 Cv flow coefficient. This Parker GP457 steam valve operates within a pressure range of 1 to 50 PSI. As a 2-way general-purpose valve, it ensures bubble-tight shut-off in critical HVACR and industrial steam applications. Note that this unit is typically sold as the valve body only and requires a compatible Parker G23 solenoid coil for operation. It is critical to ensure your system pressure does not exceed the 50 PSIG rating, as high-pressure spikes can compromise the diaphragm integrity and lead to premature failure.

• Steam-Rated Durability: Constructed with a brass body and stainless steel seat to resist corrosion and thermal stress in low-pressure steam systems.
• Optimized Flow: The 3.35 Cv rating and 1/2" porting provide consistent throughput for industrial heating and process control.
• Thermal Resistance: Specifically designed with EPT seals to handle saturated steam temperatures reaching 300°F without degrading.
• OEM Compatibility: Replaces Skinner GP457 and Parker 70564 units, allowing for seamless integration into existing pipe manifolds.

What coil is required for the Parker 70564?
This valve is designed to work with the Parker G23 coil. Always verify your system voltage (e.g., 120V/60Hz) before selecting the appropriate coil to avoid electrical burnout.

Can this valve be used for high-pressure steam?
No, the 70564 solenoid valve is rated for a maximum of 50 PSI saturated steam. Using it in systems regulated down from pressures higher than 50 PSI can cause mechanical damage to the internal components.

In what orientation should the GP457 be mounted?
For optimal performance and to prevent sediment buildup, it is recommended to mount the valve with the solenoid in a vertical, upright position, though it can function in other orientations depending on the specific piping layout.
