Flow Switches

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.

With seat and poppet geometry combined with optimized spring ranges, this industrial relief valve provides high flow rates with minimum pressure accumulation. Relief pressure can be discharged to the atmosphere or a downstream connection.

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.

Designed with tamper-proof qualities, this vent to atmosphere high-pressure relief valve is suitable for liquid or gas-based applications. With an encapsulated o-ring seal and narrow-band interchangeable springs, this relief valve eliminates seal extrusion, cold flow, and minimizes system pressure rise.

Designed with tamper-proof qualities, this high-pressure relief valve is suitable for most liquid or gas-based applications. With an encapsulated o-ring seal and narrow-band interchangeable springs, this relief valve eliminates seal extrusion, cold flow, and minimizes system pressure rise as flow demand increases.

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 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 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.
