Valve With Neoprene Diaphragm

Valve With Neoprene
Diaphragm
And Gauge Port

For Use With: Water, Oil, Air, Inert Gas
Temperature Range: 32° to 180° F

These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

Valves with a neoprene diaphragm have higher flow rates than valves with a Buna-N diaphragm.

Internal strainers trap debris.

Gauge ports let you attach a pressure gauge to monitor outlet pressure.

Corrosion-Resistant Panel-Mount Ultra-High-Pressure-Regulating
Valves for Water, Air, and Inert Gas

For Use With: Water, Air, Inert Gas
Temperature Range: 32° to 165° F

To regulate inlet pressures up to 6,000 psi in wet conditions and harsh environments, these valves have a 316 stainless steel body for exceptional corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. All have two gauge ports. They are no-bleed style, so they keep the process gases contained in the valve.

For Use With: Air, Inert Gas
Temperature Range: 40° to 150° F

Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel. Often used in systems running on air compressors, they're installed after pressure-sensitive equipment to obstruct flow and maintain a consistent operating pressure. If the system pressure exceeds the set pressure, they exhaust through the outlet. Adjust the set pressure within the range.
