A slab gate valve is a sliding valve in which the closing members are parallel rams. The closing member may be a single shutter or a double shutter with a distracting mechanism therebetween. The pressing force of the shutter to the valve seat is controlled by the medium pressure acting on the floating shutter or the floating valve seat. In the case of a double gate slab gate valve, the expansion mechanism between the two shutters can supplement this pressing force.
The slab gate valve can be divided into a manual slab gate valve, a pneumatic slab gate valve and an electric slab gate valve according to the driving mode. According to the use and use occasions, it can be divided into sluice gate valve with diversion hole, slab gate valve without diversion hole, oil plate slab gate valve, pipeline slab gate valve and gas slab gate valve.
The forged steel slab gate valve can be used in medium H2S; casting steel valve body/forged valve bonnet; low operation torque; metal to metal valve body/valve bonnet seal; metal to metal wedge/valve seat seal.
It can replace the packing online; gate, seat surface coating alloy; after a two-way valve seal.
Working Pressure：2000 psi ~20000psi
Design Performance Standards: API 6A
With reliable performance and double direction sealing structure, slab gate valve can perform well when used in high pressure service condition. In addition, it canbe used in oil field wellhead, X-mas tree and manifold system where pressure are in range of 2000psi to 20000psi.
