Product Description
Description & Specifications
| Valve Type: | Tilting disc check valve | Structure: | Swing type |
| Standard: | EN/DIN/API | Workmanship: | Investment casting |
| Sealing direction: | Single-directional | Sealing grade: | Zero leakage |
| Temperature: | -20°C<T<120°C | Operation: | Self-starting |
Characteristics
This tilted swing check valve is an improved swing check valve with short-stroke inclined disc, equipped with external hydraulic buffer for water hammer reduction. Full straight bore prevents silt jamming, suitable for sewage and slurry media. Available in ductile iron, WCB carbon steel and stainless steel with soft/metal sealing. Widely used in wastewater treatment, power plant, heating and metallurgical large-diameter pipeline systems.
Advantages
- Improved tilted swing disc shortens closing stroke to reduce water hammer; full straight bore avoids silt blockage, ideal for sewage and slurry pipelines that tilting disc valves cannot adapt to.
- This stop and check valve with large unobstructed flow passage prevents silt and fiber jamming, stable long-term operation for sewage, mine slurry and impurity-containing circulating water systems.
- Multiple body material options (ductile iron, WCB, stainless steel) cover municipal water, high-temperature steam and anti-corrosion chemical pipeline projects with outstanding cost performance.
Packing
Standard export wooden case packaging
Application Scenarios
This non return valve for water pump widely used in urban sewage treatment plant pipelines, power plant circulating cooling water, metallurgical slurry delivery lines, municipal large pump stations, thermal steam circulation systems, printing & dyeing wastewater and silt-containing industrial circulating water pipelines.
