Characteristics
This model HH44X slow closing tilting disc check valve is made of epoxy coated GGG40 ductile iron. Equipped with external hydraulic buffer for two-stage closing to eliminate water hammer and impact noise. Full EPDM rubber coated disc provides zero leakage, low flow resistance saves pump energy. Standard PN10/PN16 flanged design, widely used in municipal water supply, sewage and fire protection pump station pipeline systems.

Advantages
1.Standard backflow preventer valve HH44X design with universal flange dimensions, easy replacement for old swing check valves without pipeline modification, cutting engineering transformation cost.
2.This one way flow control valve with two-stage slow closing eliminates violent water hammer surge, effectively protecting water pumps, pipelines and pressure gauges from impact damage for long-term stable pump station operatio
3.Tilted disk check valve brings low flow resistance and energy saving. Full EPDM coated disc achieves bidirectional zero leakage to avoid water resource waste.
Packing
Standard export wooden case packaging

Application Scenarios
This tilted disk valve is widely used in municipal water supply pump stations, sewage treatment plant pipelines, high-rise fire water systems, HVAC circulating water pipes, irrigation pump stations and park water supply main pipelines.
