Parker 70742 Valve

For high-demand mechanical systems requiring precision low-pressure control, the Parker 70742 GP627 3/4" Normally Closed Solenoid Valve is a specialized service component engineered for reliability. This 2-way general purpose valve is specifically optimized for low-pressure saturated steam applications up to 10 PSI, featuring a high 7.4 Cv flow capacity to maintain system efficiency. Built with FNPT x FNPT connections, the 3/4-inch port size ensures seamless integration into existing HVACR piping systems. As a veterans' choice for steam service solenoid valves, it handles fluid temperatures up to 240°F. Note that this is a normally closed (NC) configuration, meaning it remains shut until the coil is energized, making it essential for fail-safe fluid control applications.

Key Benefits

• Optimized Steam Control: Explicitly designed for saturated steam service with a operating range of 1 to 10 PSI.
• High Flow Efficiency: The 7.4 Cv rating minimizes pressure drop, ensuring consistent performance in commercial HVAC systems.
• Rugged Construction: Engineered to withstand fluid temperatures reaching 240°F for long-term durability in demanding environments.
• Standardized Compatibility: Utilizing 3/4" FNPT ports, it fits standard industrial and refrigeration hardware configurations.

Common Questions

Can the Parker 70742 be used in high-pressure steam systems?
No. This valve is rated for a maximum pressure of 10 PSI. Applying it to systems where steam is regulated down to 10 PSI from a higher pressure source can lead to internal seat damage and valve failure.

Does this valve come with the electrical coil?
This specific part is a valve body assembly. In standard field replacement scenarios, the solenoid coil is sold separately to allow for site-specific voltage matching (e.g., 24V, 120V, or 240V).

What is the proper mounting orientation for this NC valve?
While these normally closed valves can often be mounted in multiple positions, it is professional best practice to install them with the solenoid coil upright to prevent sediment buildup from interfering with the plunger action.
