Flow Switches

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.

Designed with an integral bonnet, this forged needle valve features a PTFE and metallic wafer stem packing, which provides long-life and leak-tight service from vacuum to the maximum operating pressure.

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.

Reliably built to operate with a low operation torque while providing a long service life, this instrument ball valve offers a micro-finished floating ball design, which provides a positive seal in both directions. Also featured is a straight-through flow path, ensuring high-flows with minimum pressure drop.

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 an integral bonnet, this forged needle valve features a PTFE and metallic wafer stem packing, which provides long-life and leak-tight service from vacuum to the maximum operating 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.
