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.

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.

Compact and featuring a one-piece body, this adjustable check valve is factory-tested for leakage, crack, and reseal performance. Ideally suited for oxygen service applications, this valve also features a fully retained O-Ring seal.

Designed with a free-floating O-ring for improved tolerance to particular contaminations, this high-flow, zero-leak, low-pressure check valve is suitable for fluid and gas applications. With metal-to-metal positive stops in both the open and checked position, this valve protects the O-ring and spring from over-stress fatigue.

Use these high-pressure poppet check valves in the most demanding applications, such as medical devices, products optimized for cryogenic applications, and severe service designs.

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 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 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.

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.

With a metal-to-metal positive stop, this direct-acting inline check valve ensures a long service life and is suitable for pressure and vacuum applications. Bubble tight sealing is achieved by a line of contact between a seat and a standard elastomer O-ring with minimum differential pressure, regardless of mounting attitude.

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 with a fully retained O-ring seal, this one-piece check valve is poppet type and suitable for working pressures to 3000 psig. Also, this valve is 100% factory tested and available cleaned and packaged for oxygen service.
