Positional Control Systems
Positional Control or proportional control systems are available using either pneumatic impulse signal (e.g. 0.2 to 1 Barg) or 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. Positional control 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 allowing complete automatic positional control via input from pressure transmitters.Visit the Paladon Systems Ltd website for more information on Positional Control Systems
