POSITIONERS & CYLINDERS

ELECTROPNEUMATIC-POSITIONER

ELECTROPNEUMATIC POSITIONER

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

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

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

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

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 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.
