Advantages: Series PRHM is a 1/2" molded version of Series PR/PRH with high flow capacity, minimal drop off from set pressure, and no external metal fasteners.
Design incorporates a poppet seat, double u-cups, large area rolling diaphragm and one piece body construction. A pressure balanced shaft assures smooth and stable control, while the valve design provides excellent flow performance.
• Pressure setting is infinitely adjustable from 5 psi to 125 psi.
• Maximum inlet pressure is 150 psi.
• Available in 1/2" PVC.
• Seals in EPDM or FKM.
• No external fasteners; ideal for nasty environments.
• High performance, heavy-duty design.
• Designed for low maintenance and easy to adjust.
Corrosion resistant, also excellent for high purity and water applications. The standard connections are female NPT threaded ports. Socket, flanged and spigot connections are also available. Springs (not wetted) are stainless steel.
