Parker 70586 Valve

The Parker 70586 is a professional-grade 1/2" N/C solenoid valve engineered for low-pressure saturated steam service. Featuring a GP427 body design, this 2-way valve delivers a 3.35 Cv flow capacity to ensure consistent throughput in demanding commercial and industrial HVACR environments. Designed for normally closed operation, it utilizes 1/2-inch FNPT x FNPT porting for secure, leak-resistant integration into existing piping systems. This unit is rated for saturated steam up to 10 PSI with a maximum fluid temperature threshold of 240°F. As a veterans’ choice for steam control, it effectively manages low-pressure flow without the risk of diaphragm fatigue common in inferior models. Note that this is a steam solenoid valve sold without the coil, allowing technicians to pair it with the specific voltage required for the site. Avoid installation in systems where pressure is reduced from above 10 psig to prevent internal component damage.

Key Benefits for Technicians:

• Optimized Flow: High 3.35 Cv rating ensures minimal pressure drop across the valve in 1/2" lines.
• Rugged Construction: The GP427 body is built to withstand the thermal cycling inherent in steam applications.
• Standardized Ports: 1/2" FNPT connections allow for straightforward replacement and compatibility with standard black pipe or copper fittings.
• Precise Control: Specialized internal trim designed specifically for low-pressure steam up to 10 psig.

Common Questions:

What is the maximum MOPD for this valve?
The Parker 70586 is rated for a Maximum Operating Pressure Differential (MOPD) of 150 PSI for certain fluids, but is strictly limited to 10 PSI for saturated steam applications.

Does this valve include the solenoid coil?
No, this remains a "valve only" part number. Technicians must select and install a compatible Parker coil based on the specific electrical requirements (e.g., 24V, 120V, or 240V) of the control circuit.

Can this be used for water or oil service?
While the Parker 70586 Valve is optimized for steam, its GP427 construction may allow for other media; however, it is best practice to verify chemical compatibility with the seal material before utilizing it for non-steam fluids.
