Valve actuators with Piezotronic pilot
valves
Compact Valve Actuator Control Monitors can now be fitted with a range of low powered Piezotronic pilot valves that interface with the latest remote I/O systems and significantly reduce installed cost
A pilot solenoid and the associated control valve are often mounted separately from the switchbox on an actuated valve assembly The 007C Control Monitor incorporates limit switches, Piezotronic pilot and the associated control valve in an integrated unit that is fitted to the top of a quarter turn valve actuator or to the yoke of a linear actuator

Valve position monitors reduce field wiring 50%
K Controls has obtained ATEX gas and dust certification for EExia intrinsically safe switchboxes, switch terminal boxes and switch solenoid control centres that can reduce field wiring by 50%
Compact integrated Control Monitors for actuators
The 007C Control Monitor incorporates the position monitoring switches and the pneumatic solenoid valves in a single enclosure that is fitted to the top of a quarter turn valve actuator
The 007C is available 3/2 single acting, 5/2 double acting or 5/2 double acting "stayput".
The connections are 0.25 inch BSP and the CV is 0.5.
Optional manual override is available.
This integrated approach protects all the electrical equipment within the IP66 enclosure, reduces the overall dimensions of the actuated valve and permits connection via a single multicore cable.
Remote I/O systems reduce the number of cables running between the control room and the valves.
Many of the latest remote I/O systems are designed to operate with Piezotronic pilot valves that require less power from the system than conventional solenoid valves.
This can result in an increased I/O count per rack and a reduction in the size or number of power supplies required.
The Piezotronic valves used in the 007C Control Monitor are manufactured by ASCO Joucomatic in Germany.
The following versions are available: 6volt (3mW), 8volt (22mW), 12volt (12mW), 12volt (32mW), 24volt (46mW) and 24volt (125mW).
The 007C is certified as a complete entity to ATEX II 2 GD EExia for use with both gas and dust hazards.
The 007C can be used with remote I/O systems from manufacturers such as ABB, CEAG, MTL, Pepperl and Fuchs, Stahl and Turck.
