Supply Hebei Huafei gate valve with opening degree

For a long time, the general gate valves used in the market have commonly suffered from water leakage or rust. Our company introduced the European high-tech rubber and valve manufacturing technology to produce elastically seated gate valves with opening indication, which overcomes the poor sealing and elastic fatigue of general gate valves. , rubber aging and rust and other defects, the elastic seated gate valve with opening indication uses the compensation effect of the elastic valve to produce trace elastic deformation to achieve a good sealing effect. The elastic seated gate valve with opening indication has the characteristics of light switch, reliable sealing, It has significant advantages such as good elastic memory and long service life. It can be widely used as a regulating and intercepting device in fluid pipelines such as tap water, sewage, construction, petroleum, chemical industry, food and textile, electric power, shipbuilding, metallurgy, energy systems, etc. Features
Lightweight The main body is made of high-grade ductile iron, which is approximately 10% lighter than traditional gate valves and is easy to install and maintain.
Traditional gate valves with flat bottom seats are often caused by foreign objects such as stones, wood blocks, cement, iron filings, debris, etc. being deposited in the groove at the bottom of the valve after the pipe is washed with water, which can easily cause the valve to fail to close tightly. To prevent water leakage, the bottom of the elastic seated gate valve with opening indicator adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation and allows the fluid to flow unimpeded.
Integral rubber coating/with opening indicator elastic seat seal gate valve adopts high-quality rubber for integral inner and outer rubber. European advanced rubber vulcanization technology enables the vulcanized valve to ensure precise geometric dimensions, and the rubber and ductile ink The cast iron valve is firmly connected, not easy to fall off and has good elasticity.
Precision cast valve body/with opening indicator elastic seat seal gate valve body is precision cast, and the precise geometric dimensions ensure the sealing of the valve without any finishing work inside the valve body.
Embedded copper nut The copper nut and the elastic valve are embedded in the joint, so that the two are closely integrated into one, and will not become loose or damaged due to vibration caused by water flow.
The corrosion-resistant valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body and can be used in sewage systems.
Not easy to break In the past, traditional cast iron gate valves were often broken due to hits, collisions or heavy pressure from foreign objects. Since the main body is made of ductile iron, this situation can be greatly reduced.
Three-type ring sealing ring Since the valve stem is sealed with a three-type sealing ring, it can reduce the friction resistance when closing, greatly reduce water leakage, and the sealing ring can be replaced without stopping water.
Conducive to raw drinking. Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the valve are completely covered with rubber without rust or corrosion, and can be used for raw drinking
