It can introduce motion as well as prevent it. An actuator typically runs on electric or pressure (such as hydraulic or pneumatic). BALL VALVE ball valve is a shut-off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. BUTTERFLY VALVE The Butterfly valve is used to regulate and control, throttle the flow. They are featured by a fast operation and low-pressure drop. To make an open position from the closed, it requires only a quarter turn. Wafer, lug, Single-Flange, Flange are the regular types of butterfly valves. CONTROL VALVE A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. MOTORIZED CONTROL VALVE Motorized Control Valves (MCV) for district heating and cooling, HVAC and central heating systems ensure stable and accurate control of water, glycol mixtures and steam. ....... PNEUMATIC VALVE a pneumatic valve is a device that is used to control or modulate the flow of air (or another inert gas) in a pneumatic system. They do so by controlling the air or gas at the source, regulating its passage as needed into tubing, pipes, or devices in an automated pneumatic system. PVG PROPORTIONAL VALVE The modular electrohydraulic valves provide an almost infinite number of configurations. Varying from simple load-sensing solutions to CAN bus communication - ensuring smooth machine control...... SAFETY VALVE Safety Valve is a type of valve that automatically actuates when the pressure of inlet side of the valve increases to a predetermined pressure, to open the valve disc and discharge the fluid (steam or gas ) ; and when the pressure decreases to the prescribed value, to close the valve disc again. SOLENOID VALVE A solenoid valve is an electromechanically operated valve. ... Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. THERMOSTATIC VALVE thermostatically operated valves are a simple and reliable control solution requiring neither electricity nor control air. The range of thermostatic valves includes a series of industrial products for both cooling and heating controls. The valves are self-acting, i.e. they operate without the supply of auxiliary energy such as electricity or compressed air.
