Wedge type cast steel gate valve with different materials and application characteristics

Wedge type cast steel gate valves mainly come in three models: Z41H/Z41Y/Z41W, with connection forms: manual, electric, and pneumatic; Nominal pressure: PN16-PN200; Nominal size: DN15-800; The material of the cast steel gate valve body is carbon steel (models Z41H-16C/Z41H-25/Z41Y-16C/Z41Y-25/Z41H-40~Z41H-200), stainless steel (Z41W-16P Z41W-25P Z41Y-16P Z41Y-25P Z41W-16R Z41W-25R Z41Y-16R Z41Y-25R Z41H-40P~200P Z41H-40R~200R), and alloy steel (Z41Y-16I Z41Y-25I Z41Y-16V Z41Y-25V Z41H-40I~200I).



The sealing surface of the wedge-shaped cast steel gate valve is made of asbestos graphite or flexible graphite, suitable for temperatures between -29 ℃ and 570 ℃. It is suitable for chemical, petroleum, hydraulic, and thermal power plant systems with oil, steam, and water medium pipelines. The product has: low flow resistance coefficient, compact structure, good rigidity, smooth channel, long service life, reliable sealing, and flexible operation; Can meet various needs using standard forms of flange sealing surfaces and piping flanges.
