Fugitive emissions are a growing concern in the chemical and petroleum refining industry. Certified low-emissions (Low-E) valves can protect your facility and bottom line. Learn what they are, how they are tested, and how they can help you in this post.

Enhance system safety by preventing uncontrolled release of system media if downstream line ruptures with excess flow valves.

Our ultrahigh-purity fluoropolymer check valves meet SEMI Standard F57-0301 and provide low cracking pressure while maximizing flow and reducing pressure drop.

Features: Modified PTFE wetted components meet SEMI Standard F57-0301 for ultrahigh-purity system components; Fine thread flare and Nippon Pillar® Super 300 end connections; Low cracking and reseal pressure

The all-welded design of high-purity welded check valves provides reliable containment of system fluid while the 316L SS body offers enhanced material purity.

Check valves are designed to allow fluids to flow in one direction only and are rated for use in medium- and high-pressure applications. The variety of designs available include spring, poppet, lift, and all-welded high-purity check valves for use in a range of situations.

Read what two Swagelok specialists have to say about how a robust tagging system for hoses and valves throughout your industrial fluid systems can help you simplify maintenance and minimize system downtime.

Features: All-welded design provides reliable containment of system fluid; Forward flow starts at less than 2 psig (0.14 bar) pressure differential; Valve closes with less than 2 psig (0.14 bar) back pressure; 316L SS body offers enhanced material purity

Features: Alloy 625, alloy 825, and Alloy 2507 super duplex stainless steel materials; Available for CH4 adn Ch8 series check valves; Working pressures up to 6 000 psig (413 bar); 1/4 to 1/2 in. Swagelok tube fitting or NPT end connections; Fixed cracking pressures: 1 to 25 psi (0.07 to 1.8 bar)
