Prevents pressure build up in the interspace between relief devices
Excess flow valves are designed for use with double rupture disc or rupture disc and relief valve combinations. Elfab’s excess flow valves provide the essential facility for preventing unacceptable build-up of pressure in the space between the safety valve and the rupture disc.
As rupture discs are pressure differential devices, it is essential to prevent pressure build-up in the interspace between relief devices.
Excess Flow Valve offers essential protection
Elfab’s Excess Flow Valve provides essential safety protection and comprises a rapid shut off feature. The valve closes when exposed to a high flow rate, as occurs when a rupture disc bursts. This will prevent the unacceptable build-up of pressure, offering safety protection in many process applications.

Elfab’s Excess Flow Valves are available in 1/4” or ½“ connection and are compatible with various pressure gauge options. Supplied in Stainless Steel as standard making it suitable for a wide range of applications in arduous operating conditions.
