Plant Safety Relief Valve-2"

Plant Safety Relief Valve-2"

This 2-inch plant safety relief valve is a critical component for any concrete batch plant's aeration system. Installed on the discharge side of a positive displacement blower, it protects the equipment from damage caused by a blockage in the line. If system pressure exceeds the preset limit, the valve automatically opens to vent excess air to the atmosphere, preventing catastrophic blower failure. Once the pressure returns to normal, the valve reseats. This valve is essential for maintaining the reliability and safety of cement and fly ash aeration systems.

Key Features

• Protects positive displacement blowers from over-pressurization
• Automatically vents excess pressure and reseats when pressure normalizes
• Available in weighted or spring-loaded designs
• Features a 2-inch NPT connection for in-line installation
• Adjustable pressure settings, commonly in the 3 to 24 PSI range
• Durable construction, such as anodized aluminum or coated carbon steel, for long service life
