Investment Casting Screwed Gate Valve
The opening and closing part of the thread gate valve is a plug valve, the sealing surface is flat or conical, and the valve flap moves straight along the centerline of the fluid. The motion form of the stem has the lifting rod type (the stem lift, the handwheel not lifting), also the lifting and rotating rod type (the handwheel and the stem rotates with the lift, the nut is located on the body).

Bellow Sealed Gate Valve
The valve stem of the bellows valve adopts double sealing structure of bellows and packing to ensure the leakage and seal at the stem, especially for flammable, explosive, toxic and valuable medium. Bellows are made of stainless steel or Inconel material. The bellows seal structure is reasonable, fatigue resistant and long service life.

Pressure Seal Gate Valve
KOSEN Pressure Seal Gate Valves is a valve realizing the closing and opening function by lifting the disc up&down as the closure member. The main advantages of API Stainless Steel Gate valve are smooth flowing passage, small flowing resistance and small operation torque, while the main disadvantages of this valve are: easy-damaged sealing face, long closing&opening time, large volume&weight. Gate valve is widely used on pipeline as it's suitable to be manufactured with big size. Gate valve is and generally for cutting off purpose but not intended to be used as a regulating valve because the sealing face would be corroded by the medium easily when valve is not in fully open or closed position.

Forged Pressure Seal Gate Valve
The opening and closing parts of forged steel gate valves are gate plates. The movement direction of the gate is perpendicular to the direction of the fluid, and the forging gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate of the forging gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves are wedge-shaped and wedge angles vary with valve parameters.
