Check Valves

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.

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.

Designed for low torque, quarter turn, and positive shut-off of forward-flow up to 3000 psig (207 bar), this shut-off valve seals with a standard elastomeric O-ring seal. With a one-piece body construction, this shut-off valve also features a machined metallic replaceable plug stem.

Compact, highly accurate, and direct-acting, this vent relief valve is factory preset to desired crack pressure and/or flow specifications. With a quad ring seal, this valve provides for extreme accuracy as well as repeatability with a narrow reseal band.

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.
