Forged flang gate valve infomation:

Forged flang gate valve

The form of three types of forged gate valve cover design.

Forged flang gate valve

The first one is a form of welding-type valve cover, according to this design form of the valve, the valve body and valve cover with threaded connection, all-welded seal. customers with special requirements also can be connected through welding.

The second design is the bolted-bonnet valve cover, according to the form of this design of valve design, the valve body and valve cover with bolt nut connection, spiral wound gasket (316 folders manufacturing flexible graphite) seal. the special requirements of customers can also connect the metal ring.

The third is self-sealing valve cover, according to the form of this design of valve design, the internal pressure from Armillariella sealed,the valve body and valve cover with threaded connections.

This is the first one of the forged gate valve: Bolted bonnet forged gate valve

Gate valve

Wedge-type gate valve is the both sides of the sealing surface of the disc into the Wedge-type gate valve, Wedge-type gate valve is divided into: solid Wedge-type gate valve and flexible Wedge-type gate valve. Generally most rigidity wedge gate valve utility in small-caliber, flexible and practical in large-diameter gate. So solid gate usually use in small-caliber forged steel valves, while the large diameter cast steel valves.

The advantages of a flexible gate:

1. can save material, thus reducing the cost of the valve

2. When the valve some bias in the processing time can take advantage of their flexible damper elastic deformation to compensate for the processing of the error, thereby ensure that the valve seal.

Design and manufacture:

For casting steel gate valve, its design standards in accordance with API 600. Or API 6D,

for the casting of stainless steel and some alloy steel gate valve, its design standards in accordance with API600 or API603,

forged steel small diameter of the valve design standards in accordance with API602 or MSS SP-44
Gate valve body and valve cover connection: When the pressure in the 150LB-1500LB valve cover with bolt connections, when the pressure is the pressure in the 1500LB-2500LB using a self-sealing valve cover to connect.
Usually when the pressure is low, a small-caliber valve, you can hand wheel operation, when the caliber and pressure distribution according to customer requirements, or pneumatic umbrella gear. Electric. Hydraulic like that.
