Product Introduction

Elastic seatSealing gate valveIt is a new generation of gate valves. Compared with traditional hard sealed gate valves, it has strong corrosion resistance due to the internal and external spraying of epoxy resin powder and high-temperature film formation; The inner cavity is straight and smooth, with low flow resistance and no accumulation of dirt; The gate is covered with rubber for reliable sealing. Due to its "open stem" structure, the valve's opening status is clear at a glance. Suitable for industries such as urban water supply and drainage, building fire protection, air conditioning, and sewage treatment systems, especially for the use of direct drinking water pipelines.
