Products Details

Soft seal gate valve is a new type of valve product, which ADAPTS to the needs of water system by introducing foreign advanced technology, and overcomes the disadvantages of poor sealing performance, elastic fatigue and easy rust of ordinary gate valve. This valve uses an elastic ram to compensate for small deformation and achieve a good sealing effect. It has the advantages of lightweight, reliable sealing, good elastic memory and long life, and is widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems and other fluid transmission pipelines, as a regulating and closing device.
​
The main features of the open-rod soft seal gate valve include the integral coated gate plate, which has excellent covering performance and accurate geometry, ensuring reliable sealing and long life; The valve body is made of ductile iron, light weight, easy to install; Flat bottom seat design, does not produce slag, so that the seal is more reliable; The inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust, suitable for raw water drinking and sewage systems; The valve stem is sealed with three O-rings, with low friction resistance, easy operation and no water leakage.
​
In addition, the main performance parameters of the open-rod soft seal gate valve include pressure class 1.0MPa, 1.6MPa, 2.5MPa, valve body pressure 1.5MPa, 2.4MPa, 3.75MPa, seal test 1.1MPa, 1.76MPa, 2.75MPa, operating temperature 0 ~ 80℃, the applicable medium is water. The main component materials include body and gate made of ductile iron, gate covered with EPDM, stem made of stainless steel, O-ring seal made of NBR, etc.
