Pressure Relief Valves

Compact and highly accurate, this vent relief valve is factory preset to desired crack pressure and/or flow specifications. With an internal adjustment, this valve provides tamper-proof safety against inadvertent pressure changes and features an encapsulated O-ring seal to prevent extrusion at higher differential pressures.

Designed for high-pressure and severe service applications, this high-pressure check valve features a one-piece body and zero-leak capabilities. With a unique design that features a fully encapsulated O-ring seal with metal to metal backup, this check valve is ideal for long service life.

Built for accurate and repeatable flow control of fluids and gases, these precision metering valves feature a one-piece forged body and a screwed bonnet design. With standard panel mounting and lockable adjustments, these valves offer precise metering solutions.

Built for industrial applications requiring a rugged high flow pressure regulator, this high-capacity pressure regulator features a heavy-duty all-metallic body. Ideally suited for both gas and liquid applications, this regulator also features spring chambers and is easily rebuilt in the field.

Designed with a brass body construction, this pressure regulator and control valve features a maximum inlet pressure of 400 psi, a spring reference, as well as a fully balanced internally piloted relieving regulator. Quick-acting, its 180° adjustment knob sets outlet pressure from 0 to full line pressure.

Built for compatibility with most gases, this pilot pressure regulator is suitable for providing a reliable, constant pilot pressure to a pilot-operated or dome-loaded regulator. With a balanced design, this regulator allows for a consistent, regulated downstream pressure regardless of fluctuations in inlet pressure.

Designed with a brass body construction, this air pressure regulator features a maximum inlet pressure of 400 psi, a spring reference, and is fully balanced non-relieving. With an optimized spring and patented Venturi tube, this regulator provides high flow rates with low droop.

Use these absolute pressure relief valves in various industries, such as industrial and medical gases, cryogenics, and chemical processing. In addition, they have a seal material of fluorosilicone.
