1 Warning

• The installation and the maintenance of pneumatic actuators must be assigned to trained and qualified personnel.

• The use of the actuators outside the allowed temperature and pressure ranges may cause damage to the internal and external components.

• Prior to any installation and maintenance of the actuator, shut-off and disconnect any kind of power or air supply.

• Disassembling spring return type actuators may cause severe injuries due to compressed springs inside. The maintenance must be performed by

qualified expert personnel in full observance of the instruction described at paragraph 6. Otherwise the actuator has to be returned to MARWIN.

2 Service conditions

• AIR SUPPLY: dehumidified or lubricated air (standard). Other non-corrosive gases or

luids are a

possib

le alternative option, if compatible to the

materials of the actuator components (internal parts and lubricant).

• WORKING PRESSURE: 40 psi minimum to 115 psi maximum (2,7 bar minimum to8 bar maximum

• TEMPERATURE:

- STANDARD: - 4°F to + 185°F (-20°C to + 85°C) - NBR gaskets, Kluber Tribostar 1 EP (Centoplex2 EP) Lithium / Mineral grease

- HIGH temperature option: - 4°F to +302°F (-20°C to +150°C) - FKM (Viton) gaskets, Kluber Petamo GHY 133N Polyurea / Mineral grease

- LOW temperature option: - 40°F to +185°F (-40°C to +85°C) - silicone gaskets, Kluber Isoflex Topas NB52 barium Complex / Synthetic grease

Notes:

1. For high or low temperature options, special grease is used as the lubricant and may alter the torque generated by the actuator. For

further information please refer to MARWIN.

2. Mixing grease types is not recommended.

• ROTATION: 0°- 90°, adjustable ±5° in both end positions (double adjustment).

• LUBRICATION: The actuators are equipped with filled-for-life lubrication for normal service conditions.

• OPERATING TIME: Refer to the technical documentation. The operating time depends on various parameters such as air supply pressure,

capacity of the air supply installation (size of piping and control equipment), type of valve and fluid, selected safety factor, temperature etc.
