The simple device of manifold heat control valve is essential for smooth engine operation, even in warm summer weather. The reason is simple physics; converting a liquid (gasoline) into a vapor (air/fuel mixture) requires the application of heat.

Control valve's performance directly affect system quality and environmental pollution, so to regulator must undertake often maintain and preventive maintenance, especially for poor using conditions and important occasions, we shouldpay more attention to the maintenance work.

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).
