Positioners cylinders



ELECTROPNEUMATIC POSITIONER

A positioner for a control valve is used to adjust a valve's position based on a desired setpoint for a process variable, whether it be pressure, temperature, or flow. Types of valve positioners include pneumatic, electro-pneumatic, and digital.



LIMIT SWITCH BOX

A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection



PNEUMATIC ACTUATOR

A pneumatic control valve actuator converts energy (typically in the form of compressed air) into mechanical motion. The motion can be rotary or linear, depending on the type of actuator



PNEUMATIC CYLINDER

Pneumatic cylinder are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Like hydraulic cylinders, something forces a piston to move in the desired direction



POSITION TRANSMITTER

Position transmitter is the feedback device which gives the valve opening in percentage. ... The position transmitter can be on the shaft of a valve or on the louvers or a cooler, it will transmit the measured distance of movement



SMART POSITIONER

Smart valve positioners are digital valve controllers, microprocessor-based, current to pneumatic instruments with internal logic capability. They are designed to convert a current signal to a pressure signal to operate a valve.
