Water Seal Globe Valve with Quick - Closing Feature
Product Usage and Features
1.The product is designed and manufactured according to the national standard GB122355, with novel structure, reasonable material selection and beautiful appearance. The connection end has flange and welding, which can be matched according to different requirements of users.
2.The stuffing box is designed as a water-sealed structure, connected to a 0.6~1.6MPa water packing, with low friction and good sealing, which can isolate the entire system from the atmosphere and ensure good airtightness
3.Compact structure, flexible operation, easy maintenance, long service life. Reliable reverse seal. Packing replacement and maintenance can be carried out without stopping the machine, which is convenient and fast and does not affect the operation of the system.
