AYVAZ Pressure Relief Control Valve PN16 DN300
Mechanical overpressure protection that needs no power supply and almost no maintenance.
The AYVAZ Pressure Relief Control Valve protects your systems against overpressure with mechanical reliability. In addition, it delivers dependable protection in systems rated to the PN16 pressure class. Moreover, the GGG40 ductile iron body offers high strength and corrosion resistance. Furthermore, the polyamide pressure ring optimises sealing and reduces maintenance needs. Consequently, a maximum working temperature of 90°C allows use in thermal processes.
The GGG40 ductile iron body and cover resist demanding industrial service, while the polyamide pressure ring maintains a tight seal. In addition, the valve works entirely mechanically with no energy requirement, therefore eliminating power costs and control wiring. The DN300 flanged connection follows the EN 1092-1 standard, so it fits large-bore pipelines. Moreover, the PN16 rating and 90°C limit suit water and thermal oil circuits.
AYVAZ Pressure Relief Control Valve — Technical Specifications
This valve is used in water and thermal oil circuits for overpressure protection. In addition, it serves as a safety element at pump discharges and on heat exchanger lines. Therefore, it is preferred in power plants, petrochemical facilities and HVAC systems. Furthermore, the DN300 flanged connection adapts easily to large-diameter piping. Consequently, operators rely on it wherever process safety must be guaranteed mechanically.
