Large-diameter Stainless Steel Gate Valve Introduction：

Z41 gate valve products with small fluid resistance gate, the sealing surface erosion by erosion is small, does not change the media flow, no spoiler, pressure drop and other characteristics of the applicable pressure, temperature range, is a common cut off Valve, widely used in petroleum, chemical, thermal power plants and other oil products, water vapor pipeline connected or cut off the medium in the pipeline.(Do not use throttle).

Large-diameter Stainless Steel Gate Valve Usage：
The valve body, valve cover, gate plate, gate rod are made of stainless steel. The valve seat sealing surface is PTFE, stainless steel + carbide or surfacing carbide. The filler is carbide, PTFE, asbestos or flexible graphite. Nominal size DN15 ~ DN800, working pressure 1.6MPa ~ 20.0MPa, applicable temperature ≤ 200 ℃, suitable for nitric acid, weakly corrosive medium pipeline.
Large-diameter Stainless Steel Gate Valve Advantage：
1. Using austenitic stainless steel which has good corrosion resistance to oxidizing acid medium.
2. When the medium flows through the stainless steel gate valve, the flow direction is not changed and the 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 are labor-saving.

4. The flow direction of the medium is not limited. It will not disturb the flow or reduce the pressure. The medium can flow from any direction on both sides of the gate valve, which can achieve the purpose of use. It is most suitable for pipelines where the medium flow direction may change.
5. The gate is placed vertically in the valve body, the structure length is short..
6. Good sealing performance. The sealing surface is less eroded when fully opened.
