Cast steel gate valve: is one of the most commonly used cut-off valves, mainly used to connect or cut off the medium in the pipeline, not suitable for regulating the flow of medium. Cast steel gate valves are suitable for a wide range of pressure, temperature and caliber, especially for medium and large caliber pipes. Nominal dimension DN15~DN800, nominal pressure 1.6 MPa~20.0 MPa, sealing surface using asbestos graphite or flexible graphite, operating temperature<570, operating mode has manual, gear transmission, electric, pneumatic, etc., suitable for water, steam, oil medium pipeline.
Product features
1. the structure is compact, the design is reasonable, the valve rigidity is good, the passageway is fluent, and the flow resistance coefficient is small.
2. the sealing surface is stainless steel or hard alloy with long service life.
3. use asbestos graphite or flexible graphite, which is reliable and easy to operate.
4. Various pipe flange standards and flange sealing surface forms can be adopted to meet various engineering requirements and user requirements.
5. widely used in petroleum, chemical, hydraulic, thermal power plants of various systems of pipelines.
Z41H, Z41Y, Z41W PN16-PN200 steel wedge gate valves: manual, flange connection, open rod wedge rigid single gate plate, seat sealing surface material for stainless steel, nominal pressure PN16-PN200, valve body material for carbon steel (Z41H-16C Z41H-25 Z41Y-16C Z41H-25 Z41H-40-200), stainless steel (Z41W-16P Z41W-25P Z41Y-16P Z41Y-16P Z41Y-16P Z41Y-16P Z41Y-16P Z41Y-200) The gate valve of 25P Z41W-16R Z41W-25R Z41Y-16R Z41Y-25R Z41Y-25R Z41H-40P~200P Z41H-40R~200R, alloy steel Z41Y-25I Z41Y-16V Z41Y-25V Z41H-40I~200I.
