product manual

Z41H, Z41Y, Z41W stainless steel gate valve : manual, flanged connection type, single lever wedge-type rigid single gate, the seat sealing surface material is stainless steel, nominal pressure PN16 ~ PN200, the valve body material is stainless steel gate valve.

Z41W, Z41Y, Z41H stainless steel gate valves have compact structure, reasonable design, good valve rigidity, smooth passage, and small flow resistance coefficient. The sealing surface is made of stainless steel and hard alloy with long service life. The flexible graphite packing is used for reliable sealing. It is applied to pipelines of various systems of petroleum, chemical, hydraulic and thermal power stations with working pressure of 1.6MPa ~ 20.0MPa and working temperature of -29 ℃ ~ 200 ℃. The applicable medium is nitric acid, acetic acid, water, oil, gas and Certain corrosive liquids.

Product features: ① Meet the requirements of advanced standards at home and abroad, reliable sealing, excellent performance, beautiful appearance. ② The sealing pairing is advanced and reasonable. The sealing surfaces of the gate and valve seat are made of hard alloy with different hardness. The sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance and long life. . ③ The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance, abrasion resistance and abrasion resistance. ④ Various piping flange standards and flange sealing surfaces can be used to meet various engineering needs and user requirements.
