Valves and Valve Actuators Honeywell commercial HVAC valves control steam, water and water with glycol media in heating and cooling applications. Available in 2way and 3way configurations and sizes from 1/2quot; to 20quot;, precision valves ensure a correct fit for economic operation and long equipment life.
In the valve control loop, the actuator accepts a signal from the control system and in response, moves the valve to either a fully open or fully close position or an intermediate position depending on whether ON/OFF or continuous control is used. Types of Actuators for Control Valves.
An actuator is an implement that is built into the valve housing which dictates when the valve will open or close through the use of a controller system. As with valves, there are some different types of actuators to choose from, depending on the application in which it will be used.
Valves and valve actuators are assembled and tagged for direct delivery to any jobsite, free of charge. All you do is specify each valves location when placing your initial order and we will tag them before shipping to save you installation time and expense.
A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Poweroperated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves. Poweroperated valve actuators may be the final elements of an automatic control loop which automatically regulates some flow, level or other proc
In short, valve actuator designs are closely aligned with the design of the valve they are intended to operate. Actuators are also used in many linear motion applications where air power is not available to drive cylinders or where extra force is needed from compact designs.
Jan 18, 20200183;32;Valve actuators are a type of control valve, and there are many options available to meet plantwide and individual automation requirements. While simple in concept, consisting of a box with an input, output, and a mechanism to operate a valve,
