An Extremely Accurate and Precise Valve Positioner

The EL electropneumatic positioner combines the precision and adaptability of a digital electronic control circuit with the smoothness and efficiency of Kinetrol's proven proportional servo valve, to give the best available 4-20mA positioning performance from rotary pneumatic actuators. 

This unbeatable performance is combined with the easiest available setup procedure, easiest access to all functions and options, easy connectibility, and a truly compact all-metal enclosure, plus unique easy-set isolated angle retransmit and limit switch options inside the same enclosure.

Features

• Fast, smooth and precise control from a digital circuit and proportional servo valve 
• Simple time saving field set up
• Quick calibration via push buttons and LED feedback and easy reversal of rotation sense (clockwise/counter clockwise) without special tools or parts change. 
• Universal application
• The unit can be mounted in any orientation on to any quarter turn or linear application by connection via a NAMUR or Kinetrol square interface. 
• Loop powered
• No separate power needed, just a 4-20mA signal plus air supply. 
• Integral options - easily retrofitted modules include:
• Two wire 4-20mA isolated angle retransmit 
• Mechanical or inductive position indicator switches (general or hazardous areas) 
• Clear Cone high visibility indicator 
• Threaded conduit entries or DIN plugs for external connection.
• Intrinsically safe approved options 
• Weatherproof, compact and robust metal housing 
• Zero backlash coupling with easily adjustable switch strikers 
• Vibration and shock resistant to 4G 
• Built in gauge ports/external connections

Use Vane Actuators on the Toughest Applications

Use vane actuators on
tough applications.

The "vane type" pneumatic valve actuator is well regarded for its simplicity in design and extremely long life, even in the toughest valve actuation applications.

The heart of this simple design, and the primary reason for such long life, is the "single moving part" - a one-piece shaft and vane that moves in response to the air pressure differential on either side of the vane. A rotary vane actuator has no gears or yokes which will wear and cause problems over time. Wear, movement slop, and internal corrosion are the most typical modes of failure for rack and pinion and scotch yoke actuators.

The video below illustrate the elegance and simplicity of the rotary vane actuator and its "single moving part".

Louver and Damper Control with Vane Actuators

Besides pneumatic valve actuation, Kinetrol vane actuators are used widely on controlling industrial and commercial louvers and dampers.

The video below gives you a short visual demo of a louver being opened, closed and positioned with a Kinetrol vane actuator and electro-pneumatic positioner.

Louvers and dampers are used to stop or regulate the flow of air inside a duct, chimney, air handler, or other air handling equipment.

Some varieties of dampers are:

• Louvered Inlet Box Dampers
• Radial Inlet Dampers
• Variable Inlet Vane (VIV) Dampers
• Vortex Dampers
• Discharge Dampers

Industries that use dampers include:

• Petrochemical
• Oil & gas
• Power generation
• Construction industries

Operation of the Kinetrol Model 20 Vane Actuator with Limit Switch

The following video demonstrates the Kinetrol Model 20, double acting, pneumatic vane actuator as it closes a large butterfly valve.

The Model 20 actuator is capable of delivering 89,000 inch pounds of torque at 80 PSI. The unit you see below is equipped with a dual coil, 4-way solenoid valve to control air flow to either side of the actuator, as well as control the opening / closing time. The actuator below also is equipped with a Kinetrol Universal Limit Switch with visual indication and internal electrical contacts.

Actuators for Sludge Blowdown Valves in Municipal and Industrial Water and Wastewater Treatment Plants

Large, bulky and unreliable old sludge
blow-down valve actuator packages.

Sludge blowdown valves are used in water and wastewater treatment systems that separate solids prior to filtration. They are typically plug valves with double acting pneumatic actuators that operate on a controlled time frequency. The frequency depends on the amount of solids in the media and cycle times of every 20 minutes are common.

The pneumatic actuators that are supplied with the original equipment have been known, in some cases, to have a short performance life due to the cycle frequency and environment. Some end users have experienced the original actuators failing in 3 - 4 months. Customers who have upgraded to Kinetrol actuators have experienced performance lives of over 5 times this and still counting.
