Mechanical lock gate valve

Product overview

On the market for a long time to use a common general valve leakage or rusty phenomenon, the company introduced the European high-tech rubber seal of the elastic base seat and valve manufacturing technology of gate valve, overcomes the general bad, elastic fatigue, aging of rubber gate valve seal and defects such as rust, seal gate valves using the elastic of the elastic base seat valve production trace elastic deformation compensation function to achieve good sealing effect, The valve has the obvious advantages of light switch, reliable sealing, good elastic memory and long service life. Can be widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems and other fluid pipeline as a regulation and closure device.

Features:

Light WEIGHT: THE body material IS MADE OF advanced ductile iron, THE weight is about 20%~30% less than the traditional gate valve, easy to install and maintain.

Flat type seat: traditional gate valves are often in the water after washing pipe for objects such as stone, wood blocks, cement, iron filings, impurities, such as silt on the bottom of the valve inside the groove, easy to cause cannot close tightly and form slack phenomenon, at the bottom of the seal of the elastic base seat gate valves used in the pipe of the same flat design, not easy to cause debris deposition, make the flow unimpeded.

Overall coating: The valve is made of high quality rubber for the whole inside and outside the rubber, Europe's first-class rubber vulcanization technology using vulcanized valve can ensure accurate geometric size, and rubber and ductile iron valve is then reliable, not easy to fall off and elastic memory is good.

Precision CAST VALVE BODY: THE VALVE body IS PRECISION cast, the precise geometry of the valve body without any finishing can ensure the sealing of the valve.

Embedded nut: Threaded and elastic valve using embedded joint, so that the two closely combined into one, not due to water flow caused by vibration and loose or damage phenomenon.

Corrosion resistance: The body is coated with epoxy resin powder, which can prevent the corrosion and rust of the body, and can be used in sewage system.

Not easy to break: traditional cast iron gate valves are often broken due to external impact, collision or weight. This situation can be greatly reduced by using nodular cast iron.

Three "O" ring seal: Because the valve stem adopts three "O" ring seal design, it can reduce the friction resistance when closed and reduce the water leakage phenomenon and can replace the seal ring without stopping.

Help to raw drink: due to the inner body with non-toxic, epoxy resin coating, both internal and external surfaces of the valve in rubber completely lie without water rust or corrosion phenomenon, to drink.
