CV-3310 OR CV-3316 Inline Check Valves

• Back-flow protection without additional connections
• Outlet design
• Add to any helium supply (1/4-28 flat-bottom) port
• 3 psi cracking pressure version

This inline check valve can connect directly to any 1/4-28 flat-bottom port, Once installed, the sealing system eliminates back flow.

This unique design also eliminates the need for additional tubing cuts and connections to install traditional check valves. It accept fittings with 1/32", 1/16", 1/8" or 1.0 to 3.0 mm OD tubing.

The swept volume for the CV-3310 and CV-3316 is 16µL.

All models of these check valves have PEEK™ polymer bodies, giving them excellent chemical resistance. The sealing surfaces are PCTFE (Kel-F®), with a PTFE sealing ball and stainless steel spring.

Maximum reverse pressure rating is 2,000 psi. Going higher than this rating may cause future performance problems.

CV-3310 and CV -3316 have 3 psi (0.2 bar) +/- 1.5 psi cracking pressure. (NOTE: Pressures listed in "Compare Specs" are cracking pressures.)
