**Description:**
This wafer-style swing check valve is designed to prevent backflow in various piping systems. It operates efficiently under different pressure conditions, with a working pressure range of 1.0 MPa to 4.0 MPa. The temperature resistance varies depending on the seat material:
- **NBR:** -0°C to +80°C
- **EPDM:** -10°C to +120°C
- **Viton:** -20°C to +180°C
The valve follows international standards such as DIN and ANSI for face-to-face dimensions and flange connections. It is tested according to DIN 3230 and API 598 to ensure reliability and performance.
It can handle a wide range of media including freshwater, seawater, food-grade liquids, wastewater, steam, oils, and even acidic or alkaline solutions. Optional hydraulic counterweight is available for controlled, slow closing.
**General Features:**
- Cast stainless steel body and disc for durability
- Minimal pressure drop across the valve
- Ideal for use with clear liquids, gases, and diluted paper stock
