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

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

Resilient Seated Check Valve features:

1.Soft seal, gate plastic bag, corrosion-resistant;

2.Not easily broken, long service life;

3.For tap water, sewage, construction, electricity, medicine, metallurgy, textile, energy systems and other fluid lines

4.Fluid resistance is small, medium flows through the gate valve does not change its flow direction, so the fluid resistance is small. The company is located in:

5.Opening and closing torque is small, more open and close effort, because the gate valve opening and closing direction of flow and medium flow perpendicular to the valve, compared with the closing valve, gate valve opening and closing more effort.

6.Media flow direction is not limited, no spoiler, not reducing pressure, the medium can flow from either side of the gate valve in any direction

7.The length of the structure is shorter because the gate of the gate valve is placed vertically in the valve body and the stop valve flap is placed horizontally inside the valve body so that the length of the structure is shorter than the stop valve. The company is located in:

8.Sealing performance, fully open when the sealing surface erosion by smaller. The company is located in:

9.Full open, the sealing surface by the erosion of the working medium smaller than the stop valve. The company is located in:

10.Simple shape, casting technology is better, a wide range of applications.

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.
