316 Stainless Steel Gate Valve

The opening and closing part of the stainless steel gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle during processing. The plate is called an elastic gate. Stainless steel gate valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve.

316 stainless steel gate valve has 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, flexible graphite packing, reliable sealing, light and flexible operation. It is applied to the 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.

316 Stainless Steel Gate Valves are used for opening and closing operations in sour liquid service. For general corrosive conditions, 304 stainless steel gate valves with poor corrosion resistance can be used. Gate valves can be designed to open or close clockwise or counterclockwise. It depends on the actual situation in the application. As a leading manufacturer, we produce valves of different types, sizes and capacities. Input and output dimensions, valve strength, maximum allowable pressure, and thread and gate dimensions vary by type of stainless steel gate valve. Please contact us for more details on valves and prices.

Designed with flexible gates to ensure proper placement, these corrosion-resistant valves can absorb pipeline stress without leaking, making them ideal for refinery, chemical and other process applications.
