Control Valves

Control valves are used to control conditions such as flow, direction and level. To regulate flow, control valves can partially close to alter the amount of fluid traveling through the valve. Float valves, a type of control valve, react to the level of liquid in a storage tank and prevent overflow by providing postitive shutoff.
