The PROTEGO® Pressure Relief Valve Model P/EL is designed to safely relieve excess pressure from tanks, reactors, and process systems. It offers precise control, fast opening with 10% overpressure, and an advanced design that ensures tight sealing. Suitable for a wide range of industrial gas and vapor applications, this weight-loaded valve is especially effective for low-pressure settings, including inert gas blanketing systems.
