Control Valve Working Animation
Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially
PID Controller Action : Directing Acting & Reverse Acting
Air to open/close valves and direction of control action Control valves come in two sorts: air to open; and air to close.
Fundamentals of Valves and their Types
Valves are mechanical devices. They are basic elements with which the flow of fluids and pressure within a system can
Types of Valve Actuators
Valve actuators are devices used to position valves. They can be used to fully open and shut a valve, or
Types of Vortex Flow Meter Sensors
Types of Vortex Flow Meter Sensors are Thermal, Capacitive, Piezoelectric, Strain Gauge and Ultrasonic. It operates on the principle of Karman Vortex Street.
Valve Characteristics – Quick Opening, Linear & Equal Percentage
In essence a valve simply functions as a restriction in a flow line, with flow areas A1 and A2 and pressure
Short Notes on Different Valve Types
The essential function of a valve is to start, throttle and stop a fluid flow. Throttling, as shown in Below Figure,
What is a Segmental Wedge Flow Meter?
The segmental wedge flow meter element has a V-shaped restriction cast or welded into a flanged meter body that creates a differential pressure.
Ultrasonic Doppler Flow Meter Advantages and Disadvantages
Ultrasonic Doppler flow meter transmits an acoustic signal into the flow stream at a specific frequency to measure the flow rate.
Transit Time Flow Meter – Types, Advantages, Disadvantages
Transmit time flow meter sends and receives the ultrasonic waves between transducers in both the upstream and downstream directions in the pipe.
