Non-rising stem resilient seat seal gate valves
The uses of soft sealing gate vavle
Our resilient seat seal gate valve, produced with the introduction of European high-tech manufacturing technology of valves. RRHX gate valve completely overcomes the phenomenons of bad seals, leaks, and rust, using the whole rubber-package which lead to a good sealing effect. The resilient seat seal gate valve can be widely used in fluid lines as a regulator and the closure device. Such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems, etc. The main features of Flexible seat seal gate valve: 1. The whole rubber-packing: The good performance and accurate coverage of the geometric dimensions of the rubber-packing gate valve to ensure a reliable seal and long life. 2. The weight is light: body made of ductile iron used, light weight, easy to install. 3. Flat Seat: the bottom uses the same flatbed seat design, will not produce debris deposition and make sealing more reliable. 4. Anti-corrosion: cavity using non-toxic epoxy resin coating to prevent corrosion and rust, not only for to drink, but also can be used for sewerage system. 5. three "O" sealing, the stem used three Q-ring seal, friction resistance is small, light switches, watertight. The technical parameters of flexible seat seal gate valve: Pressure rating: 1.0Mpa, 1.6Mpa; valve pressure: 1.5Mpa, 2.4Mpa; seal test: 1.1Mpa, 1.76Mpa; Working temperature: 0-80℃; Applicable medium: water, gas and so on.
