Zero energy consumption, no impact, and ultra long lifespan

Core functions

Intelligent opening and closing achieved through flexible rubber valve discs:
-Positive water flow → valve disc automatically opens, with extremely low resistance loss
-Reverse flow of water → Valve disc instantly sealed, 100% preventing medium backflow
No mechanical transmission throughout the entire process, silent shutdown without water hammer impact

Product advantages

Ultra quiet operation: Rubber flexible seal, no metal collision sound when turned off, noise<40dB
Zero maintenance design: no complex structure, anti impurity blockage, with a lifespan of over 10 years
Energy saving and efficient: Designed with a full bore flow channel, the head loss is reduced by 50% compared to metal valves

Strong adaptability

-Corrosion resistance: EPDM/NBR rubber valve disc, suitable for clean water/sewage/weak acid and alkali media
-High temperature resistance: -20 ℃~80 ℃ (special materials up to 110 ℃)
Flexible installation: universal for horizontal/vertical pipelines, quick disassembly and assembly of flange connections
