The purpose of soft seal gate valve:
Our factory has introduced European high-tech valve manufacturing technology to produce elastic seat seal gate valves. The RRHX gate valve uses the gate's overall rubber coating to produce shape compensation and achieve good sealing effect, completely overcoming the problems of poor sealing, water leakage, and rust in general gate valves. The elastic seat seal gate valve produced by Shanghai Saitai Valve Co., Ltd. can be widely used as a regulating and shut-off device on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, shipbuilding, metallurgy, energy systems, etc. The main features of the elastic seat seal gate valve are: 1. Integral encapsulation: The gate adopts integral encapsulation, which has good coverage performance and precise geometric dimensions, ensuring reliable sealing and long service life. 2. Lightweight: The valve body is made of ductile iron, which is lightweight and easy to install. 3. Flat bottomed valve seat: The bottom adopts the same flat bottomed valve seat design as the water customer, which does not produce debris accumulation and provides more reliable sealing. 4. Corrosion resistance: The inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust. It can not only be used for drinking, but also for sewage systems. 5. Three "O" seals, the valve stem adopts three Q-ring seals, with low friction resistance, lightweight switch, and no water leakage. Technical parameters of elastic seat sealed gate valve: pressure rating: 1.0Mpa, 1.6Mpa; Valve body pressure resistance: 1.5Mpa, 2.4Mpa; Sealing test: 1.1Mpa, 1.76Mpa; Working temperature: 0-80 ℃; Applicable media: water, gas, etc.
