Swagelok SS-CHS6-20 Poppet Check Valve, 3/8 in. Tube Fitting, Stainless Steel

Reverse flow puts your intended flow direction at risk. Swagelok SS-CHS6-20 provides a poppet check valve for a 3/8 in. Swagelok tube fitting connection, with stainless steel construction and a specified cracking pressure of 20 psig (1.4 bar).

The poppet design gives your line its check function. Cracking pressure identifies the pressure at which forward flow begins. The separate valve pressure rating is 6000 psig (413 bar). You need both figures on the selection sheet because the opening requirement and pressure rating describe different operating limits.

In a Gulf Coast instrument shop, select this part for your sample or instrument line when reverse flow control and the stated cracking pressure fit the design. Collins-Oliver stocks it in Baton Rouge with same-day pickup and nationwide shipping. Ask the counter to quote this check valve.
