CPVC Pressure Release Valve
The CPVC Pressure Release Valve is a safety device engineered to automatically release excess pressure from piping systems to prevent equipment damage or failure. Made from high-quality Chlorinated Polyvinyl Chloride (CPVC), this valve is ideal for use in chemical processing, water treatment, and industrial applications involving corrosive fluids and elevated temperatures. The valve opens when system pressure exceeds a preset level and reseats once normal pressure is restored, ensuring continuous protection.
CPVC Pressure Release Valve
Key Feature of CPVC Pressure Release Valve
- Automatic Overpressure Protection: Opens instantly when pressure exceeds the preset limit.
- Chemical and Corrosion Resistance: CPVC construction ensures durability in aggressive chemical environments.
- High Temperature Tolerance: Suitable for fluids up to 93°C (200°F).
- Reliable Performance: Consistent operation with bubble-tight sealing.
- Adjustable or Factory-Set Pressure Range: Offers flexibility for various applications.
- Low Maintenance: Non-metallic components reduce rust and scale buildup.
- Compact and Lightweight Design: Easy to install and integrate into new or existing systems.
- Non-Conductive Material: Suitable for electrically sensitive applications.
