3 Use and operating principle

The PAMS08 pneumatic actuator facilitates the automatic operation of butterfly valves.

The stroke movement of a piston with internal thread that operates inside a housing is converted via a pinion into a rotary movement of the actuator shaft.

The length of the piston stroke is limited so that the actuator shaft rotates through 90° per stroke. This is precisely the angle of rotation that is required to open or close a flap in the flange-mounted butterfly valve (2).

The compressed air is admitted via a threaded connection G 1/8" (4) in the lid or on the base plate of the TOP control head. The compressed air flowing in above the piston causes the piston to move downwards and the butterfly valve flap to rotate.

LF1/FL2

The actuator is charged with compressed air above the piston. The air is discharged on the other side via a vent hole.

We reserve the right to make constructional and design changes as a result of technical developments.

4 Transportation and storage 4.1 Checking the delivery contents

When you receive the actuator, check the delivery against the order to make sure they correspond.

Check that the delivery is complete, and check its condition.

If there are visible signs of transit damage and/or packing units are missing notify the forwarding agent immediately in the consignment note. You (the recipient) should take recourse against the forwarding agent immediately in writing, and M&S Armaturen GmbH must be informed of this action.

Complaints regarding transit damage that is not immediately evident must be made to the forwarding agent within 6 days.

The recipient must carry the costs for claims made after this period.

4.2 Transport

The packing units/actuators must only be transported using suitable lifting equipment and slinging gear.

Pay attention to the graphic symbols on the packaging.

Transport the actuator carefully to prevent damage from sudden impacts; exercise due care when loading/unloading.

5 Assembly/Disassembly 5.1 Assembly

[see Fig. 1]

(a) The pneumatic actuator is initially equipped with a butterfly valve retaining bracket (3) whose dimensions match the nominal width of the butterfly valve/leak butterfly valve.

- Only use the special screws provided to fasten the bracket to the actuator, applying a tightening torque of 2.9 Nm.

(b) To perform the assembly, remove both blue clips on the butterfly valve base body.

(c) Push the retaining bracket mounted on the actuator over the butterfly valve until the outer square end of the butterfly valve flap fits precisely inside the inner square end of the actuator shaft. In doing so, check the flap position corresponds to the specifications in the table below.

(d) Then insert the screws provided (5) into the adjacent holes in the retaining bracket (3) and the butterfly valve; mount the nut (6) and tighten, applying a torque of 8Nm.

• When carrying out the assembly, make absolutely sure that the butterfly valve flaps are in the correct position!

• Mount the actuator in such a way that it cannot be damaged (e.g. by transport vehicles).

• Observe the relevant national guidelines and regulations.

5.2 Disassembly To disassemble, follow the above procedure in reverse.

5.3 Installation/Commissioning

• Pneumatic actuators may only be installed and brought into operation by specialist personnel who have received the necessary technical training, and are equipped with the experience and knowledge to carry out the tasks involved.

• Observe the following: - the actuator must be securely connected to the bracket

and butterfly valve; - lines, valves and actuators in pressurised systems

must not be detached;

- appropriate measures must be taken to prevent unintentional operation or unauthorised interference;

- only use clean, dry and oil-free compressed air;

- the pneumatic hoses must be cut at right angles using a hose cutter to ensure the necessary optimum fit in the plug connector.

6 Repairs/Maintenance

• The actuator must not be modified.

• The actuator must not be opened.

- Caution: tensioned springs!

• The actuator is maintenance free.

• M&S Armaturen GmbH cannot accept liability for claims made as a result of non-observance of these Operating Instructions or constructional changes to the actuator.

• Any other use or use outside the defined scope is considered to be improper use. M&S Armaturen GmbH will not accept liability for losses incurred as a result of improper use.

10 Certificates and testing

10.1 Resistance to cleaning agents

As the plastic surfaces are exposed to industrial cleaning processes and the environment, their resistance has been tested.

The resistance test was carried out using commercially-available industrial cleaners.

Table 2: Cleaners

Sample 1

Watery solution with

5% NOWA SR 760

(corrosive basic anorganic liquid [calcium hydroxide])

Sample 2 Watery solution with

5% NOWA ISR 700

(corrosive basic anorganic liquid [calcium hydroxide and active chlorine])

Sample 3

Watery solution with

4% APESIN RAPID

(corrosive liquid [containing ammonium compounds and tenside])

To simulate a long service life of the actuator, the plastic components (base plate and housing) were immersed in samples 1 to 3 for up to 168 hours.

The results of the tests are listed in the tables below.

As in-house tests could not cover every aspect, an independent institute has been instructed to carry out additional tests.

The plastic has been checked in accordance with the following table:
