Products Description
The opening and closing parts of cast steel gate valve Z41H-25C are gate plates.
The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve Z41H-16C/25C can only be fully opened and closed, not regulated and throttled.
Manual gate valves are suitable for a wide range of pressure, temperature and caliber, especially for medium and large caliber pipelines.
Nominal size DN15~DN800, nominal pressure 1.0mpa ~ 25.0mpa, sealing surface adopts asbestos graphite or flexible graphite, working temperature ≤570℃, operation modes are manual, gear transmission, electric, pneumatic, etc.,
mainly suitable for petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline.
Product Features
1. Compact structure, reasonable design, good rigidity of the valve, smooth channel, small flow resistance coefficient, small erosion and erosion of the sealing surface by the medium.
2. The sealing surface adopts stainless steel and hard alloy, high temperature and high pressure resistance optional materials, wide range of application, long service life.
3. Flexible graphite packing plate, reliable sealing, light and flexible operation.
4. Drive mode, motor, electric, pneumatic, gear transmission, structural form; Elastic wedge type single valve, rigid wedge type single valve plate and double gate type.
5.The applicable pressure, temperature range is large, widely used in petroleum, chemical, thermal power plants and other oil, water, steam pipeline for connecting or cutting off the opening and closing device of the pipeline medium.
