Features & Specification

Features:

Forged or Cast Body & Bonnet
All type gate valve bodies and bonnets are manufactured from forged or cast AISI 4130/4140 low alloy or AISI 410 SS steel. Other materials for extreme service, such as Inconel or Duplex stainless steel are available to order
Metal-to-Metal seal, gate to seat, seat to body, bonnet seal and stem backseat
Precision lapped faces between the gate and seat ensure a metal-to-metal pressure tight seal is maintained. Seat is lapped on both surface to give a true metal to metal seal between the body and seat. This seal is further reinforced and protected by a Teflon or Viton lip seal, giving bubble tight sealing performance at pressure below 10 psi
Bi-directional Sealing
All CCSC Gate Valve is a true bi-directional valve. Being fully symmetrical, it will effectively seal pressure from either direction without the risk of pressure lock. If the valve is used in uni-directional application, the gate and seats can be reversed to give a extra service life
All internal parts can be inline changed.
Bearing
Heavy duty thrust bearing is used to absorb stem thrust and reduce operating torque.
Non-rising Stem with Backseat
Non-rising stem made by Alloy-nitrided or 17-4 stainless steel, the pressure in the body cavity will not increase during valve operation, can replace stem packing under pressure.
