3.0 Handling3.1 Storage- Storage temperature -20 to +65C dry, free of dirt

- The painting is only a primer, intending to guard against rust during stock or transportation. Dontdamage the paintwork.

- A desiccant or heating to prevent condensation is necessary in damp rooms.

3.2 Transport- Transport temperature -20 to +65C.

- Protect against external force (impact, vibration etc.).

- Dont damage the paintwork.

3.3 Handling Before Installation- If flange covers are fitted, remove shortly before maintenance!

- Protect against atmospheric conditions e.g. wetness (applicate a desiccant).

- Correct handling protects against damage.

4.0 Description4.1 Scope of ApplicationsThese control valves are suitable for controlling the flow of liquids, gases and vapours in chemical andother processing plants and for plant engineering.The materials have been selected and matched on the basis of current DIN, AD, TRD and UVV rules.The mechanical and flow characteristics conform to standard DIN EN 60534.The engineer planning a plant is responsible for selecting the correct valve for a given application. Thespecial features of the valve concerned must be taken into account.

- Valves for oxygen application (O2) have a fixed plate.

- Valves for Ammonia (NH3) acc. to TRD 451-452 must be free from nonferrous metalswith flanges DIN 2512 form N.

acc. to TRB 801 No.34 for ammonia storage tank systems, bodies withshoed ends must be stress-relief-annealed.

- ARI-Valves of GG-25 are not allowed in systems acc. to TRD 110.

- Valves for inflammable, aggressive or toxic media, must be off tensile material.

- With applications for media that demand special criteria, please consult.

- -marking for applications acc. to Pressure Equipment Directive.

4.2 Operating PrinciplesARI control valves are especially suitable for actuation by pneumatic or electrical actuators.

Three plug types are available to suit the various applications:parabolic plug (standard pattern)perforated plugV-port plug

The flow through control valves with parabolic and V-port plugs is always against the closing direction. Inthe case of control valves with perforated plugs, gases and vapours flow against the closing directions, butliquids flow through in the closing direction.

If a pneumatic actuator is to be used on a straight-way valve with a perforated plug with the fluid movingin the closing direction, a higher closing force will be needed. This is to prevent vibration as the plugapproaches the closed position.

Pressure-balanced plugs can be provided if the actuator force is inadequate.

Oil and grease freefor oxygen application

4.4 MarkingDetails of the CE-marking on the name plate of the valve:

5.0 Installation5.1 General Notes on InstallationThe following points should be taken into account besides the general principles governing installationwork:- Remove flange covers if present.- There must be no foreign bodies inside the valve or piping.- Pay attention to the direction of flow: see markings on the valve and refer to the operation and installation

instructions (point 4.2).- Centre sealings between the flanges.- Connection flanges must mate exactly.- If the valve is handling steam, the piping must be laid with a gradient to prevent water from accumulating

in pockets. Condensation traps are needed to prevent water-hammer.- All parts must be free from stress after installation.- The valve must not serve as a fixed point. It must be carried by the piping.- Protect the valve from dirt, especially during construction work. Strainers or filters shoud be installed

before the valves.- Install compensators to compensate for thermal expansion of the piping.- Keep the thread and shaft of the spindle free from paint.5.2 Requirements at the Place of InstallationThe place of installation should be easily accessible and provide ample space for maintenance andremoving the actuator. Stopvalves shoud be installed before and after the controlvalve to enablemaintenance working without draining the piping system. The valve should preferably installed verticallywith the actuator at the top. Inclined or horizontal installation without supports is permissible only withlight actuators.For this installallation position, the two distance columns (or joke) have to be above each other in theverical plane.

Permissible servo weights for valves with unsupported horizontal spindles:20 kg for DN 15 - 3225 kg for DN 40 - 6535 kg for DN 80 - 100

The pipes must be lagged to protect the actuators from excessive heat. Sufficient space must be left for themaintenance of the spindle packing.To ensure that the control valves function correctly, the pipe run should be straight for at least2 x DN upstream and 6 x DN downstream of the valve.

CE-marking According to the Pressure Equipment Directivepart 3, valves without safety function are onlyallowed to bear the CE-marking DN32 onwards.

Valves with safety function are:Type 440 DP-G / 441 DP-G andType 440 / 440-D with FR2.1 and -sign

5.3 Installation Instructions Concerning ActuatorsNormally, control valves are supplied complete with actuator fitted.It is not permitted to mantle / dismantle actuators with valves operating and service conditions(temperature and pressure) (see 2.3). The actuators must be assemble as describe in the operatinginstructions during conversion and maintenance.During assembly work, the plug is not be turned on its seating at closing pressure.

Caution!Care must be taken with the bellow type valves when actuators are mounted or removed. Hold the valve-spindle against turning with an open-end wrench.When retrofitting actuators, the maximum permissible force for valve actuation must be taken intoaccount.The maximum permissible actuation forces are:

6.0 Notes on Dangers During Installation, Operation and MaintenanceDANGER !Operation can be completely safe only if the valve is properly installed, put into operation and maintainedby trained personnel (cf. point 2.3 Qualified personnel) paying full attention to the warnings in theseoperating instructions. In addition, the general installation and safety rules for piping and plant installationmust be observed, and appropriate tools and safety equipment are to be used. Strict attention must be paidto the operating instructions during all work on the valve and when handling it. Injury or damage can becaused by ignoring them.

When used as an end-blockage, a safety precaution is recommended by maintenance works.

7.0 Putting the Valve into Operation- Before putting the valve into operation, check that the material, pressure, temperature and direction of

flow are as specified with the plans of the piping system.

- Regard the TRB 700.

- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.

DANGER !Before putting a new plant into operation or restarting a plant after repairs or modification, always makesure that:- All installation and assembly work has been completed!- Only qualfied personnel (see point 2.3) are employed to start the plant!- The valve is in the correct position for its function!- Existing guards have been attached and in good order.

4.0 Description

4.1 Scope of Applications

The pneumatic actuators are to be mounted on the top of valves and are necessary to operate thevalves (spindle movement) under service conditions.The units are suitable for being employed in control systems used in the chemical industry.The actuator units can achieve a high positioning force after only a short control time and fulfil allthe demands of the explosion safety regulations without additional measures needing to be taken.

4.2 Setup and Operating Mode

By means of the pneumatic actuator units, pneumatic control signals are converted into a translatorymotion. The necessary restoring force is generated by means of the compression springs on the bulkof the diaphragm plate.

In case of air fall-off, the actuator will be restored by means of the spring force in the startingposition.

The operating mode of the actuator is the following:Spindle moving out(on air failure) orSpindle moving in(on air failure)

This operation is obtained and dependent on the assembly of the springs.

By using a rolling diaphragm, linear rod forces during long lifts can be obtained.
