  • Working Temperature: -50℃~+180℃

  • Body Material: 304/CF8 Stainless steel

Product details:

RE Lift Check Valve (1/2″~21/2″)

 

 

Uses
A) RE general-purpose check valve uses rubber sealed disk featuring good sealing effects and is applicable to air, steam, water, oils and various other liquids and gases compatible with the valve material.
B) REQ silent check valve has no spring but achieves sealing by the aid of the gravity of the valve core; it is applicable to 1) macro-pressure gases, and 2) applications where vibration noise is caused by low gas flow. It must be horizontally mounted with the bonnet on the top.
