Pressure and Vacuum Control Valves

Miniature Ultra-High-Pressure-Regulating
Valves for Water, Air, and Inert Gas

For extremely high-pressure applications in tight spots, these valves handle the same inlet pressures as other ultra-high-pressure-regulating valves within a smaller footprint.

Back-Pressure-Regulating Valves for Air and Inert Gas

Use these valves in pipelines.

Panel-Mount Vacuum-Regulating Valves for Air

Panel-Mount Vacuum-Regulating Valves for Air

Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel-mount nut.

Hydraulic Valves

Tamper-Resistant Pressure-Relief Hydraulic Valves

The pressure setting on these valves cannot be adjusted while they are installed.

Pressure-Relief Screw-In Hydraulic Valves

Set a specific pressure and these valves will maintain it.

Air-Powered Motion and Control

Air-Exhaust Control Valves

Quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

Elbow Air-Exhaust Control Valves

Elbow Air-Exhaust Control Valves

Quickly vent exhaust air to the atmosphere or divert it to another place in your system to speed up the movement of equipment. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

Air-Exhaust Flow Control Valves

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.
