Process control valves function in a variety of ways to control manufacturing processes, but all process control valves require some sort of actuator -- either hydraulic, pneumatic or electric, etc.

Directional control valves are specified generally by the number of ports or ways (lines attached to thesymbol

At times, we have applications where a large control valve is required at high process pressure. This combination requires a pneumatic actuator with substantial area and displacement volume in order to operate the valve.

Angle float control valves controls the liquid height of the water pool or tower. There is a specially reinforced nylon diaphragm inside it, which separates the valve into upper and lowers two cavities.

You must select the most suitable control valve for your application, as control valves come in various categories according to their operation and construction.

The control valves discussed in this section are applicable to throttling control (i.e., where flow through the valve is regulated to any desired amount between maximum and minimum limits).

A self actuated pressure control valve can be used to control the pressure at either upstream or downstream of the control valve. If the pressure upstream to the valves is used to throttle the control valve, then the upstream pressure is maintained at a specified set point and such a valve is known

The function of the lift control valve is to regulate the oil flow to and from the lift rams according to the signals transmitted by the ELC calculator.
