Water Hammer Control Non Slam Check Valve EPOXY Coated Quick Close Ductile iron​

How do we control the quality of machining

1. High-precision CNC lathe processing parts.

2. Advanced Milling Machines

3. UT Inspection to ensure welding quality

4. Weld Polishing

5. 100% Appearance & Size Inspection online (thickness, roundness, etc.)

6. Size & Appearance Shaping

Features:

· High strength ductile iron body used for durability and less weight.
· Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
· One of the lowest head loss check valve, big save in pumping power cost, valve disc with shorter stroker and spring reverse faster than most of check valve.
· Coated with powder epoxy both inside & outside for corrosion resistance.
· Bronze bushing reduce wearing problem during operation.
· Hydrodynamic design with spring ensures non slamming and water hammerless.
· Stainless steel spring hidden in the diffuser under protection while valve in operation.
· Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
· Installation can be vertical/horizontal/inclined.
· Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
