Wholesale Brass seat GGG40 swing check valve sewerage pipeline Manufacturers, Manufacturer
Product Description
This swing check valve is cast from GGG50 ductile iron with epoxy anti-corrosion coating. It adopts brass metal sealing surface, featuring wear resistance and temperature resistance without aging trouble. The swing disc brings large flow passage and low pressure loss, mitigating water hammer. It automatically prevents medium backflow, widely used in hot water, water supply, boiler and HVAC pipeline systems.
- The ductile iron body of swing type NRV with high toughness and impact resistance, epoxy coating anti-rust, stable pressure bearing for long service.
- The brass metal seal of swing valve is wear-resistant and temperature-resistant without rubber aging, suitable for hot water pipelines, not easy to be scratched by tiny impurities.
- Swing disc provides large flow area and low flow resistance, gentle opening and closing to relieve water hammer and protect pipeline equipment.
