Pneumatic Rack & Pinion Actuators
General Overview
Designed and manufactured for the ultimate in durability and reliability.
Pneumatic Rack & Pinion Actuators provide outstanding service life.

Compact Rack & Pinion Design utilizing the whole piston area develops output torque.

Quarter-Turn Operation

Designed for using on a variety of valve types: ball valves, butterfly valves, plug valves dampers etc.

Hard anodized aluminum body.

Chromate corrosion protection on all aluminum components.

Suitable for indoor and outdoor installation.

Adjustable travel double stops. 90 degrees +/- 5 degrees.

Double acting type torque outputs from 328 in-lbs. to 56552 in-lbs. with an 80psi air supply.

All moving parts are factory lubricated. No additional lubrication required.

Removable/replaceable drive inserts.

Pre-loaded spring assemblies.

ISO 5211 mounting.

NAMUR (VDI/VDE) accessory mounts.

Anti Blow-Out pinion design.

Maximum pressure rating: 116 psi.

Compatible media: clean, dry air, filtered noncorrosive gas or light hydraulic oil.

Mounting dimensions are Keystone standards and ISO standards for direct mounting capabilities.
Features

The hard-anodized actuator body along with the control modules is protected from corrosive
environments with a protective finish that has passed a 1,000 hour-salt spray test per ASTM B117.

Die cast aluminum end caps with polyester powder coat finish. Using the same end caps on both SR
and DA actuators allow customers to lower inventory costs and give quick interchangeability.
Allowing customers to convert SR units to DA units by adding springs only.

Die casting aluminum piston. The precision-machined rack is chrome plated for optimal performance.
It has a three point guiding system for moving stable and extended service life. High qualified
seamless O-rings for airtight sealing and long service life.

Anti Blow out pinion design.

Superior stability and field safety spring package (sizes 63 through 140). The EM pneumatic actuator
utilizes two embedded springs, an inner and outer springs allow five different spring torques. The
design also allows equal and evenly distributed force to each piston extending service life.


The encapsulated spring package with corrosion-protected can be easily disassembled with
a standard Allen wrench for conversion of double-acting to spring-return configuration on
sizes 52 through 140.
Anti-friction housing guide band ensures no metal-to-metal contact and provides wear
protection between housing and piston for extended service life. Ideal for modulating or
control applications.

Bi-directional travel stops

Adjustable stops on the center of the body provide the flexibility of accurate valve rotational positioning
at the end of the ‘open’ and ‘close’ stroke.

The total travel of 100 degrees allows for end of travel adjustment of 5 degrees at both open and close
positions.

Travel stops must not be used for manual override purposes.

Travel stops on actuators with reverse action require special build and must be specified at time of
ordering.

With reference to the above diagram it can be noted that the torque of a double acting actuator
remains constant throughout the complete action. The user can decide on which model to
choose according to his/her own specific requirements, using the following guidelines:
1.
Define the maximum torque of the valve to automate.
2.
To obtain a safety factor increase the torque value chosen by 25-50% (subject to the type of valve and working conditions).
3.
Once the torque value suggested is obtained consult the torque chart and in relation to the corresponding air pressure find a
torque value exact to or exceeding the one obtained.
4.
Once the torque value is determined move horizontally to the column “model” to find the actuator model required.

Rotation
With reference to the above diagram the torque of a spring return actuator is not constant, but decreasing.
This is due to the action of the springs that when compressed during air actuation counter act the piston movement and accumulate energy which
will be available in a decreasing way during the rotation in version. The torque given by the actuator is defined by four fundamental values.
Opening rotation (Press air working)
Torque output at closed position (0o)=Actuator torque deducts unfolded springs torque
Torque output at opened position (90o)=Actuator torque deducts compressed springs torque
Closing rotation (Springs working)
Torque output at opened position (90o)= compressed springs torque.
Torque output at opened position (0o)= unfolded springs torque
The user can decide on which model to chose according to his/her own specific requirements, using the following guide lines:
1.
Define the maximum torque of the valve to automate.
2.
To obtain a safety factor increase the torque value chosen by 25-50% (subject to the type of valve and working conditions).
3.
Once the torque value suggested is obtained consult the torque chart and in relation to the corresponding air pressure find the torque
value exact to or exceeding the one obtained, taking account of the lower value between the opening and closing positiionvalues.
4.
Once the torque value is determined ,move horizontally to the column “model” to find the actuator model required.
