Check & Vent Valves | Boiler Supplies Check Valves by Check All Valves Check-All Style BU - Bushing Valve
The Check-All Valve Bushing Valve is a check valve with a standard bushing housing. This Check All Valve is adaptable to many types of service applications. It has very little restriction and produces a low pressure drop. It can be used quite effectively in systems where flow and pressure drop are critical by the use of a reducer coupling. The Check All Valve Bushing Valve also makes an excellent vacuum breaker. The high flow rate insures maximum effectiveness for vacuum breaker service. By reversing the direction of flow it can also be used as a low-pressure relief valve.
The bushing thread sizes are designated by two sets of numbers; thefirst being the male thread, the second the female thread.
