Pneumatic Cast Iron Check Valve DN150

Key Features

1. Pneumatic Actuation: Features a high-efficiency pneumatic actuator for fast, automated valve operation, suitable for hazardous or explosive environments (ATEX compliance available on request).

2. Rugged Cast Iron Construction: Built to endure high pressures (PN16/PN25) and resist corrosion, ensuring durability in harsh conditions.

3. DN150 Flanged Connection: Compliant with EN 1092-2/ISO 7005 standards, enabling easy installation and compatibility with standard pipeline systems.

4. Spring-Assisted Dual Disc Design: Ensures swift, positive closure to prevent backflow, minimizing water hammer and system downtime.

5. Low Maintenance Design: Self-cleaning seat and hardened stainless steel hinge mechanism reduce wear and extend service life.
