Rotork Valvekits, the Rotork flow control group’s specialist valve mounting kit company, has been appointed as the UK stockist and distributor for the well established Centork range of valve positioners.

Centork pneumatic positioners are designed for the operation of quarter-turn or linear actuated valves in accordance with a proportional control signal. The design utilises a robust aluminium enclosure and stainless steel components for long-term reliability in harsh operating environments.

Standard features include simple, user-friendly zero and span settings and NAMUR interfaces for easy valve and accessory adaptation. Optional limit switches, position indicators, gauges for main and control signal pressure and electronic position transmitters can be fitted to meet the demands of most operating requirements, whilst a ‘smart’ positioner is also available, incorporating micro-processor based electronics for valve monitoring and diagnostics.

Excellent operating performance delivers repeatability of less than 0.3% of full range, hysteresis of less than 0.5% of full range and 99% full range linearity. All models are available with ATEX certification for operation in hazardous areas.

The Centork appointment, which will enable off-the-shelf delivery of many products to customers in the UK, is the second distributorship agreement that Valvekits has announced in recent weeks. In April the company also announced an exclusive stockist and distributor appointment for the industry-leading Pneumatrol Namur range of solenoid valves.
