007C for pneumatic actuators now available with Piezotronic pilot valves

The 007C Compact Valve Actuator Control Monitor from K Controls 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.

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 GmbH in Germany. The following versions are available:

6 volt (3 mW),8 volt (22 mW),12 volt (12 mW),12 volt (32 mW),24 volt (46 mW) and 24 volt (125 mW). 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.

K Controls products can be fitted to a wide range of linear valves

K Controls switchboxes and position transmitters can be fitted to a wide range of linear valves. We can also provide design assistance with mounting brackets.

In addition the 007C Control Monitor can be fitted to a wide range of linear valve actuators such as those used on control valves, globe valves, knife gate valves, or diaphragm valves. Linear actuators do not always conform to the standard mounting patterns defined in VDI/VDE 3845 and are not often supplied with a Namur solenoid interface. To bring all the benefits of the Compact 007C to linear actuators please send us your enquiry.
