I recommend using thecontrol valvemanufacturer has provided. However, to be considered under the verification e Cv easier we have a simple formula Cv value can be calculated following them. Table of Contents Cv value calculation A) Simple Cv Value Formula: Case of the Liquid QL:Flow rate (m3...
balancer includes a perforated element interposed between the inlet port and the intermediate chamber, allowing fluid passage only through at least one opening of the perforated element and an elastic element at one face of the perforated element facing the inlet port of the fluid into the valve ...
However, one can calculate the flow using the control valve opening if the following information are available. [ul] [li]Inlet and outlet pressure[/li] [li]Details of pipe between the pressure measurement points and the control valve[/li] [li]original control valve calculation[/li] [li]...

Furthermore, a special speed regulating valve was developed to improve the start-up steadiness of HVC. All the above mentioned studies on the stability of HVC are based on the valve control method. However, the pump control system is also widely used in various industrial applications for ...
high speed on/off valve; control strategy; performance regulation; intelligent maintenance; intelligent coding; function programmability1. Introduction Electro-hydraulic servo systems are widely used in robotics [1], flight simulators [2], aero-engines [3], and other fields due to several advantages,...
The calculation method estimates the amount of air intake based on the speed of engine rotation, air temperature, and the pressure detected at the air intake pipe by the intake air pressure sensor, i.e., the manifold absolute pressure sensor (MAPS). Nevertheless, this method can measure the ...
The device (114) has an error calculation device calculating an error of an intake air flow of a motor (101). An impact ratio calculating device is operated when the motor is in an intermediate operating range to calculate an impact ratio between impacts on mean phase changing mechanisms (112...
Relief rate calculation for control valve failure In natural gas processing, petroleum refineries, and petrochemical and chemical plants, automatic control systems are normally used to achieve smooth and safe operation as well as maximize production and minimize hazards for equipment an...

When the satellite signal is lost, the data calculated by the inertial navigation system can be used to locate the tractor through corresponding calculation. The inertial navigation system can also measure the tractor's attitude angle information. The navigation computer calculates the deviation value ...
