A flat gate valve is a sliding valve with a closing part parallel to the gate.The shutoff may be a single gate or a double gate with a bracing mechanism in between.The gate pressure to the seat is controlled by the medium pressure acting on the floating gate or the floating seat.In the case of double gate flat gate valves, the retracting mechanism between the two gates can supplement the compression force.

ANSI WCB cast steel flat gate valve
Cast steel flat gate valvesare body-cast gate valves for use in 2,000 psi to 5,000 psi oilfield wellheads, tree, gas tree, and manifold systems.Meet the latest version of NACE MR-01-75 specification requirements, suitable for H2S operating conditions.Body casting molding, cost-effective.
A flat gate valve is a sliding valve with a closing part parallel to the gate.The shutoff may be a single gate or a double gate with a bracing mechanism in between.The gate pressure to the seat is controlled by the medium pressure acting on the floating gate or the floating seat.In the case of double gate flat gate valves, the retracting mechanism between the two gates can supplement the compression force.
Flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to driving mode.According to the purpose and usage, it can be divided into plate gate valve with guide hole, plate gate valve without guide hole, oil field plate gate valve, pipeline plate gate valve and gas plate gate valve, etc.
Using the characteristics:
1.This series product adopt new floating type sealing structure, is applicable to pressure is not greater than 15.0 MPa, temperature - 29 ~ 121 ℃ on the oil and gas pipeline, as control opening and closing of the medium and adjusting device, the product structure design, select material appropriate, strict testing, convenient operation, strong corrosion, wear resistance, erosion resistance, is a kind of ideal new oil industry equipment.
2.Structural features and working principles
(1)With floating seat, two-way opening and closing, reliable sealing, flexible opening and closing.
(2)The gate is provided with guide strip for precise guidance, and the sealing surface is sprayed with cemented carbide for erosion resistance.
(3)High bearing capacity of valve body, straight through channel, full open, and gate guide hole through and straight pipe similar, flow resistance is very small.Stem with compound packing and multiple seals for reliable seal and low friction.
(4)When closing the valve, turn the handwheel clockwise and move the gate down to the bottom. Due to the effect of medium pressure, push the inlet seal seat towards the gate direction, forming a large specific seal pressure, thus forming the first seal.At the same time, the gate plate is pressed to the outlet end seal seat to become a double seal.
(5)Because of the use of double sealing, so can not affect the work of the pipeline under the condition of replacement wear parts.It is an important characteristic that our products have priority over similar products at home and abroad.
(6)When the gate is opened, turn the handwheel counterclockwise, move the gate upward, and connect the diversion hole with the passage hole.With the rise of the gate, the through-hole is gradually enlarged. When it reaches the limit position, the diversion hole coincides with the passage hole. At this time, it is fully open.
