Swagelok SS-CHS4-20 Poppet Check Valve, 1/4 in. Tube Fitting, Stainless Steel

20 psig (1.4 bar) is the cracking pressure your drawing must call for with this check valve. The stainless steel Swagelok SS-CHS4-20 brings a poppet check function to a 1/4 in. Swagelok tube fitting connection for directional flow control.

You select the poppet valve to permit forward flow and oppose reverse flow. Its 6000 psig (413 bar) pressure rating is distinct from the cracking pressure that marks the start of forward flow. Keep those values separate when you compare the valve with your line requirements.

For your Gulf Coast analyzer panel, this configuration fits a check point specified for the stated connection size and opening pressure. Include that cracking pressure on the order. Collins-Oliver stocks the valve in Baton Rouge, with same-day pickup and nationwide shipping. Request pricing for your panel parts list.
