Parker 70563 Solenoid Valve

The Parker 70563 Solenoid Valve is a 2-way normally closed pilot-operated valve designed for rigorous industrial and HVACR fluid control. This 1/2" FNPT solenoid valve is specifically engineered to handle low-pressure steam up to 10 PSI and hot water up to 150 PSI, featuring a robust brass body and high-grade stainless steel seat insert to minimize erosion. With a 3.35 Cv flow coefficient, it ensures high-capacity throughput for air, water, and non-corrosive oils. The Teflon diaphragm provides exceptional thermal resistance, maintaining a safe fluid temperature range from -20°F to 240°F. Note that this is a Parker GP407 series replacement unit; the solenoid coil is sold separately, allowing contractors to pair it with specific voltage requirements (AC or DC) for on-site steam system maintenance or boiler feed applications.

• High Thermal Stability: The Teflon diaphragm and stainless steel trim are rated for 240°F, preventing premature failure in steam and hot water loops.
• Reliable Sealing: The normally closed (NC) configuration ensures a positive shut-off during power loss, critical for safety in fuel or steam line applications.
• High Flow Efficiency: A 3.35 Cv rating allows for significant volume with minimal pressure drop across 1/2" piping systems.
• Industrial Durability: Forged brass construction stands up to the mechanical stress found in commercial plant environments.

What is the maximum pressure for steam applications?
The Parker 70563 is rated for a maximum differential pressure of 10 PSI for steam. For air, water, or oil, the maximum working pressure is 150 PSI.

Does this valve come with the electrical coil?
No, this part number refers to the valve body and internal assembly only. You must select a compatible Parker coil based on your specific voltage (e.g., 120V/60Hz or 24VDC) for operation.

Can this valve be mounted in any orientation?
For optimal service life and to prevent sediment buildup in the pilot orifice, it is recommended to mount the valve with the solenoid in the upright vertical position.
