Control Valve FAQs

A control valve is used to control the hydraulic characteristics of the media being pumped through the valve - they are able to reduce, sustain and increase system pressure as well as regulate the medium's flow rate.

Preventing a system from exceeding its designed pressure and flow rate protects the equipment from the damaging effects of water hammer and ensures consistent operating perameters for more reliable performance.

Equilibirum ball float valves are designed to regulate flow into tanks in order to maintain a consistent liquid level. The float attached to the valve rises and falls with the liquid in the tank, opening and closing the valve at pre-set levels to prevent overflow when levels are high and refill the tank when levels are low.

Some models of control valves allow for complete open/closed adjustment in a pipeline, however specifically designed isolation valves will operate the most efficiently.

Pressure reducing valves react to upstream pressure fluctuations in real time in order to maintain a consistent pressure level within a system. Preventing the system from exceeding its maximum pressure rating will protect it from damaging incidents such as water hammer.

Relief vavles are similar to pressure reducing valves in that they are designed to maintain a consistent system pressure, however relief valves do this by releasing excess air/liquid through a designated outlet in order to decrease pressure and prevent surges.
