The grooved gate valve is the introduction of European high-tech rubber and valve manufacturing technology The production overcomes defects such as rubber aging and rust. This valve uses the elastic gate plate to produce trace elastic deformation compensation to achieve a good sealing effect. The valve has significant advantages such as light switching, reliable sealing, good elastic memory and long service life. The product is widely used in tap water, sewage, seawater, and water treatment. , environmental protection, construction, fire protection, petroleum, chemical industry, electric power, food, medicine, textile, shipbuilding, energy and other industry pipelines as a regulating and intercepting device.
Flat-bottomed valve seat
General gate valves often cannot close tightly due to foreign objects such as cement blocks, iron filings and other debris deposited in the groove at the bottom of the valve, causing leakage. The bottom of the elastically seated gate valve adopts the same flat bottom design as the pipeline, which is not easy to cause debris accumulation and allows the fluid to flow unimpeded.
Precision cast valve body
The valve body is precision cast with precise geometric dimensions so that the inside of the valve body does not need to be processed at any time to ensure the sealing of the valve.
Valve plate rubber coating
The valve plate is made of high-quality rubber for overall internal and external rubber sealing. Europe's first-class rubber vulcanization technology allows the vulcanized valve plate to ensure precise geometric dimensions, and the rubber and ductile iron valve plate Then it is firm, not easy to fall off and has good elastic memory.
Ring seal
Since the valve stem and valve cover adopt a three-way ring seal design, the friction resistance during switching can be reduced, water leakage can be greatly reduced, and the flow of media in the pipeline can be continued. Replace the sealing ring.
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 plate are completely covered with rubber, so that there will be no molten iron or corrosion, allowing for raw drinking.
Labor-saving device
D can be equipped with an additional labor-saving device. The required torque is about normal/only a small handwheel is needed to operate the fully open or fully closed operation under pressure. The labor-saving device is used in every action. At one time, the valve needs to be fully opened and then the labor-saving function can be restored.
