Safe, efficient and simple to operate, it meets all of your performance requirements:
A high-capacity pressure relief valve has been incorporated as an integral part of the coupler body. This serves two purposes: First, when functioning with other relief devices in the system, it will prevent a keg from reaching pressure in excess of recommended working pressure. Second, it allows the user to relieve pressure when needing to prevent or troubleshoot
Designed for maximum flow, it can be used for either single or a series of keg dispensers. Specially designed pressure inlet nipple eliminates the need for a coupling washer when used with standard Taprite check valve. Flow of gas is controlled by lever handle; in up position pressure is off, when down it is on. The coupler can be quickly disassembled for cleaning and periodic service.
No special tools required.
