Parallel Slab Disc Gate Valve 

Parallel slab disc gate valve have better advantages in easy open & close due to small torque requred, lower flowing resistance and avabialbe for the medium with solid particle when comparing with wedge disc type gate valve.  The valve size of parallel slab disc gate valve is from 4 inch to 24 inch matching valve pressure from class 900 to class 4500. They normally used in the high pressure main streaming pipeline or high pressure bypass water feeding pipeline etc. The main function is  to cut off or cut on the medium controlled by electric actuator or handwheel. Valve material can cover carbon steel, alloy steel, special steel, such as A105,F11,F22,F91,F92,WB36 etc.
