Water-sealed Gate Valve

Product Features

Characteristics:

1. The water-sealed Gate Valve cover packing chamber has a water seal structure. When water with a pressure of 0.6~1.0MPa is introduced into the interface, the system can be isolated from the atmosphere and has good air tightness.

2. The selection of materials is superior to ordinary medium and low pressure valves. The pressure-bearing parts are made of cast steel, and the valve stem and sealing surface are made of stainless steel.

3. The Water-sealed Gate Valve has a parallel double gate structure, with reliable sealing, easy opening and closing, and easy maintenance.

4. The connection forms of this series of valves are divided into flange and welding. There are two ways of driving seeds: manual and electric.


Water-sealed Gate Valve

The water sealed gate valve is designed for the efficient control of pipelines with a nominal pressure of 100 MPa and operational temperatures reaching 425°C. This valve is well-suited for handling various working mediums, including water, steam, oil, and non-corrosive gases. It proves particularly effective in the vacuum condensing system of steam turbines within thermal power plants.
