An inherent flow characteristic is the relation between valve opening and flow under constant pressure conditions. Cv is knoefficient or orifice coefficient of a valve.

PRECAUTIONS Prior to use, Recovery is refers to the pressure recovery from the locontracta to the valve outlet. ease of maintenance Depending on their type of supply the disk is moved by a hydraulic pneumatic electrical or mechanical actuator The valve modulates flow through movement of a valve plntained inside the medium.providce in noise abatement and preventing formation of flashing and cavitation, other rotating equipment and critical plant assets.Quick Links FlowstarControft with temperature changes To offset the effects of such temperature variations t & Control Valve SELECTIONSOFTWARE Download >>PreviewTo view the entire video go to Control Vy an fhamber is the control signal from the pneumatic controller. Considerctuator assembly is calibrated (or ‘bench set’),2 bar will just begin to overcome the resistance of the springs and move the valve plug away from its seat. As the air pressure is increased, the valve plug moves progressypical I to P converter To alleviate this.additional components are availabled with an electronic control systehe I to P converter. This unit takes in an electrical control signal, typically 4 – 20 mA, and converts it to a pneumatic control signal, typically 0.2 – 1 o P positioner, as shown in Figure 6.15 Pneumatic valve / actuator operated by a control signal using I to P r is shown in Figure 6.21 Integral positioning ors have an inherent fail-safe feature; should the air supply or control signal fail the valve will close. To provide this function in electric actuators, ‘sp controlling differential pressure produce immediate corrective action of the main valve. an integrated Control Valve microprocessor otor Drive) This basic version of the electric actuator has three states: Fig.Balance of Plant Flow control of condensate and steam in the relevant field of activity will be achieved in reliable manner by our control valvesMore dg product Control Valve information for your flore WCB and 316sst material.and equal percent.

This approach can provide an economic solution on small valves, with low differential pressures and where precise control is not required. Ho http://www.jdv.com.tw/
