Gate Valve Flange Type DN40 ~ DN 1200 Durable Resilient Seated Check Valve

Characteristics:

1,the bottom of the pipe diameter the same light hearth seat design, does not produce debris siltation, more reliable seal.

2,the valve plate with the overall quality of rubber coated,advanced rubber vulcanization after curing technology allows the gate to ensure accurate geometry, and rubber and ductile iron

covered with solid, not falling.

3,the valve body using non-toxic epoxy resin coating, excellent corrosion resistance, to prevent secondary pollution of drinking water.

4,valve stem 0 three-ring friction is small, lightweight switch,no leakage.

5,the body material used QT450-10, high strength, light weight, long service life...

Resilient Seated Check Valve FEATURES

⊙ Treating with rubber

Both inner and outer are coated with advanced knowledge of rubber vulcanization then making

sure of the elasticity of rubber ,and make sure the exact geometry dimension. Rubber and ductile

cast iron valve hand together hardly. This can avoid fall-off due to long-term use.

⊙ Anti- corrosion

Both inner and outer are coated with non-toxic powder epoxy resin to strengthen the capacity of Corrosion resisting and raise the quality

of water supply.

⊙ Ruggedization

The older ductile iron valve is easy to rupture after being impacted by nonego. It can stop

rupture depend on the good mechanics capability of ductile iron .

⊙ Three “○” sealed ring

With the three “O” – rings, the leakage can be greatly reduced and the “O” – ring can be

replaced under this condition with pressure and without stopping water. The thrust axletree

reduces the frictional resistance and lowers the operational torque. And it can be switch seal

ring without opening and closing.

⊙ Rigid round body

The body is founded minutely, the rigid geometry size ensure inner sealing of valve without

any process.

⊙ Light weight

This body is made of ductile iron, it is 20%-30% lighter than the olds. Easily to fixing and

servicing.
