Products Details

Soft seal gate valve is a special design valve, mainly used to control the flow of fluids, such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, Marine, metallurgical and energy systems in the pipeline as a regulating and truncating device. Here's the Chinese version, based on search results:
​
Product Overview: Grooved dark rod soft seal gate valve adopts cavity free structure, the internal and external surfaces of the valve body and valve cover are coated with epoxy, and the surface of the valve plate is covered with rubber, which fundamentally eliminates the possibility of corrosion. Instead of packing the valve stem seal, the "O" ring is used to make the seal more reliable. The valve can be operated manually, electrically or pneumatically as required.
​
Structural features:
​
Integral rising valve stem design, compact structure;
Valve stem nut and two valve plate structure, no blocking phenomenon;
Through the channel, leaving no leakage space;
The stem is sealed with an "O" ring.
Main component materials:
​
Valve body: ductile iron;
Valve plate: ductile cast iron coated with EPDM;
Bolt: galvanized;
Sealing ring: NBR;
Valve cover: ductile iron;
Valve stem: stainless steel;
"O" ring: NBR.
Connection size: Depending on the DN size, the valve length (L) and connection height (HA) will be different, such as DN50 L is 178mm, HA is 313mm; The DN400 has an L of 457mm and a HA of 1665mm.
​
Performance parameters: the nominal pressure of the valve is 1.0~2.5MPa, the nominal size is 50~600mm, the working temperature is 0~80℃, the applicable medium is water, oil, gas, etc., the main material is ductile iron and cast steel.
​
Open rod soft seal gate valve features:
​
Integral plastic coating: valve plate integral plastic coating, with good coverage performance and accurate geometry, to ensure the reliability and service life of the seal;
Lightweight: The valve body is made of ductile iron, light weight, easy to install;
Corrosion resistance: the body cavity is coated with non-toxic epoxy resin to prevent corrosion and rust, suitable for drinking water and sewage systems;
Three "0" seal: The valve stem is sealed with three "O" rings, with low friction resistance, light switch and no leakage.
The grooved soft seal gate valve has been widely used in many industrial applications because of its excellent sealing performance and corrosion resistance.
