DS/Z61H Water Seal Gate Valve

One. Structure and characteristics

1. The valve cover packing chamber of this product has a water-tight structure. When water with a pressure of 0.6～1 MPa is introduced into the interface, the system can be isolated from the atmosphere and ensure that the system has a good airtight seal.

2. The DS/Z series adopts double gate two-way elastic sealing, which is flexible, fast and reliable in opening and closing.

3. The product structure is simple, compact and reasonable, convenient for maintenance and long service life.

4. Used as an opening and closing device on the pipeline, it must be in a fully open or fully closed state, and must not be used to adjust the flow.

5. There are two types of valve connection methods: flange and welding, and the driving method is manual and electric.

6. The DS series water seal valve is suitable for opening and closing devices on pipelines with nominal pressure ≤ 1O.O MPa, working temperature ≤ 425 ℃, and working medium of water, steam, oil and non-corrosive gas, especially suitable for thermal power plants Steam turbine vacuum condensing system.
