Water Seal Parallel Gate Valve

The water-sealed parallel gate gate valve designed by Dazhong Valve Group is suitable for cutting off or connecting the medium in the pipeline in the vacuum condensing system of the gas turbine and the system pipeline that is required to be isolated from the atmosphere in the petroleum and chemical industry. The stuffing box is designed with a water-tight structure, the sealing ring is matched with advanced and reasonable, the opening and closing parts are sealed with double gates, and the surface of the valve stem is treated with anti-corrosion hydrogenation.

• Water seal gate valve is suitable for nominal pressure PN1.0~10.0MPa, working temperature -29°C~450°C thermal power station, gas turbine vacuum condensing system and system pipelines that require isolation from the atmosphere for petroleum and chemical industry, cut off Or connect the medium in the pipeline. The applicable medium is water, steam, oil crystal and non-corrosive gas, etc.

• The stuffing box is designed as a water-tight structure, with 0.6~1.6MPa water packing, low friction, good sealing, can isolate the system from the atmosphere, and ensure a good air seal. It has good environmental performance .

• The matching of sealing rings is advanced and reasonable, which improves the sealing performance and has a long service life.

• The opening and closing parts are made of double gates and two-way elastic sealing, easy to open and close, and reliable sealing.

• The surface of the valve stem is treated with anti-corrosion hydrogenation, which has good corrosion resistance and scratch resistance.
