Positional control or proportional valve positioning systems are available using either a pneumatic impulse signal (e.g. 0.2 to 1 Barg) or an electrical signal (normally 4 to 20 mA). These systems are designed either to have customer defined pre-set positions or to have full control of the valve between the open and closed positions. Valve positioning systems can be used in conjunction with on/off production or ESD controls and can be utilised for a partial test system e.g. using digital controllers. PLC controllers can also be incorporated to provide complete automatic valve positioning control via input from pressure transmitters.
