Demonstration of NAMUR Mount Solenoid Valve with Manual Bypass Option on Kinetrol Actuator
This video demonstrates a very helpful solenoid valve option, the manual bypass feature. The technician uses a NAMUR mounted solenoid valve with built-in bypass on a Kinetrol vane actuator to show you exactly how the option works.
How to Install the Optional 4-20 mA Feedback Mechanism on the the Kinetrol AP Pneumatic Positioner
This video describes how to install the optional angle retransmit circuit (4-20 mA feedback mechanism) on the Kinetrol AP pneumatic positioner.
The angle retransmit circuit is an externally powered (8–30v DC) linear 4-20mA feedback module, rangeable down to 30 deg. for full 4-20mA span. The module's retransmit pot is a high quality conductive plastic servo–type with ball bearings, coupled with a zero-backlash feedback pot drive. The combination provides long life and high precision.
The Kinetrol AP positioner moves an actuator to a position set by a 3-15 psi control signal and holds it there. It is designed to drive a rotary or linear actuator to a position set by a 3-15 psi (0.2 to 1.0 bar) signal and hold it there until the signal changes.

How to Install the Kinetrol AP Pneumatic Positioner
This video describes how to install a Kinetrol AP pneumatic positioner on a Kinetrol vane actuator.
The Kinetrol AP positioner moves an actuator to a position set by a 3-15 psi control signal and holds it there. It is designed to drive a rotary or linear actuator to a position set by a 3-15 psi (0.2 to 1.0 bar) signal and hold it there until the signal changes.
When a signal pressure is applied to the diaphragm it moves the force balance lever clockwise against the tension of the feedback spring. This moves the spool valve, supplying air pressure to one side of the actuator while exhausting trapped air from the other side.
The feedback shaft follows the movement of the actuator and turns the cam counter clockwise, pushing the cam follower and increasing the tension on the feedback spring until it balances the forces on the diaphragm and moves the spool valve to its hold position.
The input signal and desired position is determined by the cam profile. A cam giving 0-90° output movement linearly proportional to a 3-15 psi (0.2-1.0 bar) signal is standard, and almost any desired characteristic can be supplied to order; if it cannot be found in the list of existing options contact Kinetrol.

Kinetrol Actuators Protect People and Property with Reliable Performance in Chemical Plant Fire

| The Kinetrol actuator is completely unrecognizable, having been melted in a fire. |
The building houses a $30 million dollar compressor that supplies process air to reactors to begin the PTA manufacturing process.
As part of the safety system, (2) two 6" class 150 high performance butterfly valves with Kinetrol 097-120 and open/closed limit switches were installed on process air lines of one production unit.
During the fire, the two Kinetrol actuated valve assemblies performed exactly as required, shutting the valves tightly and keeping them shut even after the heat of the fire completely melted the actuator housings.
