DIN soft seal buried gate valve

Product name: DIN soft seal buried gate valve

Model No.: (DIN) F4Z45X-16Q-100

---

Brief introduction:

Gate valve is one of the widely used industrial valves in fluid transport projects. For traditional gate valves, there are some weaknesses, like fluid leakage, internal corrosion,etc. This resilient soft seal gate valve adopts the novel structure design, strict manufacturing technology, and new materials, which overcomes the defects of traditional gate valves and has reliable sealing performance, long service life, and is easy and convenient to operate and maintain.

Characteristics of Soft seal buried gate valves:

1. overall rubber coated. Ductile iron gate valve has characteristics of overall rubber coated, great sealing Performance, accurate physical dimensions, which can guarantee the zero leakage, long service life, and small flow resistance.

2. The valve stem is lengthened, which is convenient for high position operation.

3. corrosion resistant. The inside of the valve body is coated with non-toxic epoxy resin, which is anti-corrosive and rust resistant. That kind of gate valve not only can be used for drinking water piping line systems,also can be used for wast water delivery pipe line systems.

4. Triple seal. There are triple O-type sealing rings used for valve stem, which has small frictional resistance, and is easy to open and close.

Applications of soft-seal buried gate valve:

This kind of ductile iron soft seal buried gate valve can be used in life water delivery systems, urban water supply

and drainage systems, sewage treatment systems, chemical fluid delivery system, construction, urban

environmental protection,petrochemical industry, pharmacy, food,textile, metallurgy, electric power and

other industries, to cut off the mediums in the water supply and heat supply pipe line systems.
