Technical parameters and characteristics of open rod soft seal gate valve

　　Technical parameters of open rod soft seal gate valve: pressure grade: 1.0 MPa, 1.6 MPa body pressure resistance: 1.5 MPa, 2.4 MPa sealing test: 1.1 MPa, 1.76MPa working temperature: 0-80 C suitable medium: water, gas, etc.

　　Characteristics of open-stem soft-seal gate valves: Traditional gate valves often accumulate in grooves at the bottom of valves due to foreign materials such as stones, wood blocks, cement, paper scraps, debris, etc. after washing pipes with water. It is easy to cause water leakage phenomenon that can not be closed tightly. The bottom of the soft-sealed gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris deposition and make the fluid unimpeded. The valve plate uses high quality rubber as the whole inner and outer rubber. The first-class rubber vulcanization technology in China ensures the precise geometric size of the vulcanized valve plate, and the connection between rubber and nodular cast iron gate plate is reliable, which is not easy to fall off and has good elastic memory. Corrosion resistance: The valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body, and can be used in sewage system. Not easy to break: In the past, traditional cast iron gate valves were often broken due to external impact, collision or overlap. As the valve is replaced by ductile iron, this situation can be greatly reduced. Three "O" ring seal ring: Because the valve stem adopts three "0" ring seal ring design, it can reduce the friction resistance of the switch, greatly reduce the leakage phenomenon and can replace the seal ring without stopping water construction. Helpful Drinking: Because the inner part of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate are completely covered with rubber without rust or corrosion, so it can be used as raw drinking. Precision Casting Body: Precision casting is used for the body. The precise geometric dimension ensures the sealing of the valve without any finishing. Light weight: The valve is made of spheroidal graphite casting, and its weight is reduced by about 20%-30% compared with the traditional gate valve. Easy installation and maintenance.

　　Soft sealing gate valve overcomes the defects of poor sealing, elastic fatigue and rust prone of general gate valve. Soft-sealed gate valve is a replacement product of traditional gate valve. It uses elastic gate plate to compensate micro-deformation and achieves good sealing effect. It has the advantages of light switch, reliable sealing, good elastic memory and long service life. It can be widely used in water, construction, food, sewage, power, medicine, metallurgy, textile, energy system and other fluid pipelines. It is used as a regulating and closing device.
