Gate valve (TH-GTV)

详情

Gate valve GTA gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact of the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr*3, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate. According to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve.

Area of application

• Dimensions Conform to EN*****2,ANSI B*6.5
• Testing Conform to EN******1, API**8
• Worm-gear/hand-wheel
• Pneumatic-actuator

• Gate valveAdvantages:

• Less effort when opening and closing.
• Water hammer phenomenon is not easy to produce. The reason is the long shutdown time.
• The structure length is small.
• The structure is compact, the valve has good rigidity, the channel is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, and the service life is long. The use of PTFE packing is reliable and easy to operate.
• Disadvantages
• During the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches.
