Triple Duty Valves
A pump is designed to move medium from one place to another, generating pressure. Some of the mediums that pumps will move are water, slurry, gas or air. When pumps do not function properly they can cause problems for the components downstream as well as to itself. These problems include: inlet flow restrictions that can cause the pump to starve and overheat; negative head pressure that cause downstream problems as well as premature wear on the pump mechanism; reverse flow that can cause the pump to work harder in keeping the downstream pressure accurate; turbulent flow causing the downstream components to wear prematurely and possibly malfunction; vibration causes piping stress and possibly water hammer if air is present in the system.
To protect pumps, Spence Engineering offers a full line of pump protection products including suction diffusers, triple duty valves, foot valves, flexible connectors and check valves.
Triple Duty Valve:
The triple duty valve is three valves in one; a check valve that provides one direction flow; a balancing valve which moderates the downstream flow; and a shutoff valve for pump isolation.
