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.

Suitable for both gas and liquid applications, this poppet check valve features a fully retained O-ring seal design that permits full-rated pressure in the checked direction. With a metal-to-metal positive stop, this valve provides a trouble-free service life in the most demanding applications.

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.

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.

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.

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, this precision metering valve features a one-piece forged body and a screwed bonnet design. With standard panel mounting and lockable adjustments, this valve offers precise metering solutions.

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.

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.

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.

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.

Use these metal diaphragm regulators for steam, water, or oil applications.
