[DS/J61H Water Seal and Vacuum Stop Valve Product Usage]

The DS/J61H-25, DS/J61H-40, and DS/J61H-63 water seal globe valves are suitable for thermal power plant return water condensation systems with a nominal pressure of PN2.5-6.4MPa and a working temperature of 0-450 ℃, as well as systems requiring isolation from the atmosphere in petroleum and chemical industries. They cut off or connect the medium in the pipeline.

【 DS/J61H Water Seal and Vacuum Stop Valve Product Features 】

1. The product is designed and manufactured according to the national standard GB12235, with a novel structure, reasonable material selection, and beautiful appearance. The connecting end has flanges and welding, which can be matched according to different user requirements

2. The stuffing box is designed as a water sealed structure, connected with water fillers of 0.6~1.6Mpa, with low friction and good sealing, which can isolate the entire system from the atmosphere and ensure good airtightness

3. The valve stem has undergone tempering and surface nitriding treatment, providing good corrosion resistance and scratch resistance

4. Compact structure, flexible operation, convenient maintenance, and long service life

5. The reverse seal is made of stainless steel threaded connection seal seat or austenitic stainless steel body welding, ensuring reliable reverse sealing. Filler replacement and maintenance can be carried out without stopping the machine, making it convenient and fast without affecting system operation
