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.

Back-Pressure-Regulating Valves for Air and Inert Gas
- For Use With: Air, Inert Gas
- Temperature Range: 0° to 150° F
Often used to protect equipment running on air compressors, these valves obstruct flow to maintain sufficient operating pressure in your system. If the system pressure exceeds the set pressure, they exhaust through the unthreaded relief port. Adjust the set pressure within the range. Valves have two gauge ports.

Panel-Mount Back-Pressure-Regulating Valves for Air and Inert Gas
- 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.
