CPE General-Purpose Check Valve (Max. 400 bar)

CPE Stainless Steel Check Valve (1/8″–2″)

Uses
CPE general-purpose check valve: Compact size, good sealing performance.

CPE vale core has a damping chamber that provides good vibration-resistance for liquid.
CPE is applicable to air, steam, water, oils and various other liquids and gases.
CPE-*-Q check valve: very low cracking pressure; applicable to: 1) micro-pressure; 2) vacuum; 3) applications with very low gas flow.
