PNEUMATIC CONTROLLERS

SIEMENS cylinders

The electric cylinder comprises a CASM linear unit supplied by SKF and a SIMOTICS S-1FK7 motor. The CASM linear unit converts the rotary motion of the SIMOTICS S-1FK7 motor into a highly dynamic linear movement and is a perfect substitute for pneumatic or hydraulic cylinders in many applications. By contrast with pneumatic and hydraulic cylinders, electric cylinders allow the driven machine to approach any position with extreme precision solely on the basis of setpoints transferred to an inverter from the SINAMICS S110 or SINAMICS S120 range.

 

SIEMENS Positioners

The positioner – a multi-talent which can optimally handle a wide spectrum of challenges: whether in a compact design for a wide range of standard applications or as a remote version. The digital positioner applies the state-of-the-art HART, PROFIBUS PA or Foundation Fieldbus protocol communication standard with additional diagnostics functions such as the valve performance test. The optional “Fail in Place” function causes the valve to remain in the last position – the all-rounder thus provides comprehensive flexibility.

NAKAKITA

Nakakita Seisakusho was founded in 1930 with Frontier Spirit  as its core company policy. Since then, our mission has always been to develop innovative valves and other fluid control systems to enable our customers to keep abreast of the challenges of their industries.

 

SMC cylinder

SMC offers a variety of hydraulic cylinders are available in compact, round body, JIS or tie-rod types. Nominal pressure ranges from 3.5MPa to 16MPa. Bore sizes are available, depending on the series, from 20 to 160. Auto switches are available on most models.

The air-hydro unit consists of a converter and a valve unit that are compactly integrated. It converts air pressure to an equivalent hydraulic pressure, and this hydraulic pressure is used for operating an actuator, thus solving the problem that is associated with the compression characteristics of air.

Hydraulic filters are designed for installation between the pump and reservoir tank.  Their main function is to protect the pump from contaminants.

YAMATAKI,AZBIL

Actuators are powered by an air supply and open or close control valves in response to signals.Positioners are attached to actuators and receive control signals from the controller.
