Stainless steel gate valve production: valve body, valve cover, gate plate, gate rod using stainless steel material, seat sealing surface of PTFE, stainless steel + cemented carbide or surfacing cemented carbide, packing is generally made of cemented carbide, PTFE, asbestos graphite or flexible graphite. Nominal size DN15~DN800, working pressure 1.6mpa ~ 20.0mpa, applicable temperature ≤200℃, suitable for nitric acid, weak corrosive medium pipeline.

1, the use of austenitic stainless steel, oxidizing acid medium has good corrosion resistance.

2, the medium flows through the stainless steel gate valve does not change its flow direction, fluid resistance is small.

3. The movement direction of the gate is perpendicular to the flow direction of the medium, the opening and closing torque is small, and the opening and closing force is less.

4, the medium flow direction is not restricted, does not disturb the flow, does not reduce the pressure, the medium can flow from both sides of the gate valve in any direction, can achieve the purpose of use, the most suitable for the medium flow direction may change in the pipeline.

5, the gate is vertically placed in the valve body, the structure length is short.

6, good sealing performance. When the sealing surface is fully opened, the erosion is small.
