Proportional control valve

Th 143033
Click here to enlarge image

Hayward ProFile2 corrosion resistant, all plastic proportional control ball valves provide two linear flow curves, one for fast opening and one for slow opening. The percentage of flow through the valves with either flow curve is equal to the degree of opening. As the valves are opened or closed, the flow varies in direct proportion to the valve opening. This permits predictable, accurate control of the downstream flow rate with a 1/4 turn valve in many automated flow control applications in the water and wastewater treatment industries.

The new second generation of Rotork IQ electric valve actuators are designed to meet a wide range of demanding MOV requirements for water and wastewater applications. The IQ actuators provide quarter-turn operation and the IQT actuators provide multi-turn operation. The actuators can communicate in several ways and provide a wide array of important valve operation data for making predictive maintenance decisions. Operators can make field adjustments easily with the actuator's infrared setting tool, thereby avoiding the time-consuming task of having to remove actuator covers.

Halogen Valve Systems' Hexacon control system closes Chlorine and SO2 cylinder and ton container valves in less than one second when activated by leak detectors, earthquake sensors, and local or remote "panic buttons." The controller is a battery operated computer-based system that handles up to six Eclipse Actuators. Operators need not enter a toxic atmosphere to shut off a chlorine leak. All Fire Codes recognize and approve the "automatic-closing fail-safe shutoff valve" system in lieu of a scrubber treatment system. When combined with a leak detection system, this shutoff system stands guard 24 hours a day.
