â… ï¼ŽProduct Introduction
This is a high-performance non-return valve engineered for reliable fluid control in potable water and general industrial applications. It features a ductile iron body with an epoxy coating, which provides exceptional corrosion resistance and durability in harsh operating environments.
The valve uses a spring-assisted axial disc mechanism. This design ensures fast, tight closure even at low differential pressures. It effectively prevents reverse flow and water hammer, protecting downstream piping, pumps, and equipment from damage. It is WRAS approved, confirming its safety and suitability for potable water systems.
Ⅱ．Product Features
- Superior Sealing Performance: The EPDM sealing ring and precision-machined stainless steel disc ensure bubble-tight shutoff even at low pressures, eliminating leakage risks.
- Water Hammer Prevention: The spring-loaded axial disc design enables rapid, controlled closure. This eliminates the shock of sudden flow reversal, protecting the pipeline system.
- Corrosion Resistance: The epoxy-coated ductile iron body and stainless steel internal components offer excellent resistance to corrosion and chemical attack. This extends the valve’s service life.
- Wide Temperature Compatibility: Operates reliably across a temperature range of -10°C to 120°C, suitable for both hot and cold water applications.
- Low Maintenance: The robust, wear-resistant construction and simple internal design minimize the need for frequent servicing, reducing operational costs.
