Manual flange stainless steel knife gate valve

1、 Product Overview of PZ73H-10P Knife Gate Valve

The PZ73H-10P knife gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion. The opening and closing component of a knife gate valve is a gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. Manual knife gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The manual knife gate valve produced by our company has the advantages of simple and compact structure, reasonable design, lightweight and material saving, reliable sealing, easy and flexible operation, small volume, smooth channel, low flow resistance, light weight, easy installation and disassembly. It can work normally under working pressure of 1.0MPa-2.5MPa and operating temperature of -29-650 ℃.

4、 Structural characteristics of PZ73H-10P knife gate valve product

For a long time, the general gate valves used in the market have generally suffered from water leakage or rusting. Our company has introduced European high-tech rubber and valve manufacturing technology to produce elastic seat seal gate valves, which overcome the defects of poor sealing and rusting of general gate valves. The elastic seat seal gate valve uses the compensating effect of slight elastic deformation generated by the elastic gate plate to achieve good sealing effect. This valve has significant advantages such as lightweight opening and closing, reliable sealing, good elastic memory, and service life. It can be widely used as a regulating and intercepting device on pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, energy systems, etc.
