A name of the product “DUAL PLATE CHECK VALVE” self say about design construction and operation of valve. This type of check valve is simple assembly of 1) dual -double flap or can say door, 2) single piece casted heavy duty body, 3) spring and 4) stem. On the centre of body two stem holes are provided to mount / fix dual flap plate and which perform from centre as like a hinge in direction of flow with tension of spring. One stem perform as flap holes guide shaft and another as disc opening limit stop pin. Spring supports to the disc to get normal close position of valve.<br />
Body have choice of either elastomer soft rubber seats or metal to metal seat for higher pressure and temperature application with StelliteF6 Hard face.  In elastomer rubber seated check valve seat choice options are Neoprene, EPDM, NBR, Nitrile, Buna-N, Hypalon, Ebonite, Silicon, Viton etc.<br />
