I assume you’re using two valves because throttling a single variable speed pump or one control valve on the discharge of a constant-speed pump wouldn’t provide enough rangeability. If your ...

One such transformation is the integration of smart valves and actuators in industrial fluid management. These previously unimagined devices are reshaping how fluids are controlled, monitored and ...

Usually, the first step is determining the required valve characteristics, which describe the relationship between flow through the valve and the value of the control signal received by the valve ...

The valve stem, a cylindrical shaft, connects the handle (or actuator) with the inner mechanisms in gate valves, as well as other shutoff, flow control, and directional-control valves.

The fail-safe functions can be one of the following: close at no power, close at no control, open at no power and open at no control. When adding a fail position in a pneumatic or hydraulic actuator, ...

The dirty service trim valve (left) handles outgassing liquids with entrained solids common in HHPS applications. The turbine bypass valve (right) has an integrated desuperheater to control steam ...

The system uses two ED02 electropneumatic pressure-control valves and two PRA pneumatic ISO piston-rod cylinders for pressing, plus a third cylinder for clamping parts in place.

A well-designed J-T valve will provide consistently accurate positioning regardless of process changes over a long service life. Poorly designed J-T control valves are susceptible to excessive ...
