POPU Valve: Stainless Steel Flanged Gate Valve
The opening and closing parts of the gate valve are the gate plate, the movement direction of the gate plate is perpendicular to the fluid direction, the gate valve can only be fully opened and closed, can not be adjusted and throttled, the gate plate has two sealing surfaces, and the two sealing surfaces form a wedge.
Stainless steel gate valve is a kind of gate valve, the material requirements for the valve body are relatively high, generally there are 304, 316 and other material choices.

1. The valve body is all precision casting valve body, the second shot blasting treatment, fine appearance, no grit, each batch of castings are marked with furnace number, to facilitate the production tracking.
2. All stainless steel materials 304/316, etc. are guaranteed laboratory tests, with a material sheet.
3. Double sealing ring structure is adopted on both sides of the valve shaft to avoid leakage of the valve shaft.
4. From the production of each part to the finished product packaging and delivery, strict quality control is carried out for each link.
5. Each valve is subjected to double pressure testing of the housing and seal to ensure it qualifies.
