Section 1: Before You Start

This section explains:

•

Base safety procedures

•

Where to find detailed information relating safety.

•

Storage guidelines.

Installation, adjustment, putting into service, use, assembly, disassembly and

maintenance

of the pneumatic actuator must be performed by qualified personnel.

Failure to follow the above guidelines will void warranty.

Actuator must be isolated both pneumatically and electrically before any (dis)assembly

starts. Before mounting or (dis)assembly, the actuator consults the relevant sections of

this manual.

ϭϭ



Installation, Operation and

Maintenance Reference Documents

Before you start, read the following documents:

•

All chapters in this manual.

•

Safety Guide (Document No. TL.32.A210-SG.EN).

Failure to read the Safety Guide will void the warranty.

Not following the instructions of the Safety Guide can lead to failure of the product and

harm to personnel or equipment.

ϭϮ



Warehouse Storage

•

All actuators should be stored in a clean, dry warehouse, free from excessive

vibration and rapid temperature changes.

•

All actuators should not be stored directly to the floor surface - it must be placed

in racks/shelves or use a pallet.

Prevent moisture or dirt from entering the actuator. Plug or seal both

air

connection ports.

Failure to follow the above guidelines (Warehouse and On Site Storages) will void warranty.

Identification

The A210-211-212-213 Series Rack and Pinion actuators are available as double-acting or

spring-return versions. 15 models are available, ranging from 9 Nm to 3500 Nm (80 to

31000 lbf.in)

nominal torque output.

The A210-211-212-213 Series-Series uses standardized interfaces for solenoid, switchbox

or positioner

mounting (VDI/VDE3845; NAMUR). The valve interface is equipped with

an insert in the pinion bottom that allows both ISO5211 or DIN3337 mounting.

The springs in the spring-return version allow a fail action in case of loss of air supply

pressure (Fail-to-Close or Fail-to-Open).

As from size PA032 and PA040 double-acting versions have flat end caps to reduce

actuator length and internal air volume.

Intended Use

The A210-211-212-213 Series Rack and Pinion actuators are intended for the automation

and operation of quarter-turn valves like Butterfly, Ball and Plug valves.

Rack and Pinion actuators can also be used to operate dampers or any other quarter-turn

applications.



The Proval actuators typically operate counter clockwise to open and clockwise to close. The direction of pinion rotation

(CCW to CW) can be reversed changing the orientation of pistons as shown in the picture above.
