Unique, externally adjustable, and wear compensating, this screwed bonnet-type needle valve offers a long and trouble-free service life in most liquid or gas applications.

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 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.

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.

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.

Particularly suitable for applications in instrumentation and control panels to open and close circuits or isolate gauges, this quick opening valve offers a unique design for full-closed to full-open operation with a 60° turn of the knob.

With dependable leak and bubble-tight options, this valve provides free flow in one direction and shut-off in the opposite direction. Encapsulated ball virtually eliminates flutter yet provides a positive check.
