Type 2012 Operating instructions 1 OPERATING INSTRUCTIONS The operating instructions describe the entire life cycle of the device. Keep these instructions in a location which is easily accessible to every user and make them available to every new owner of the device. Warns of a potential danger. ▶▶ Failure to observe these instructions may result in moderate or minor injuries. NOTE! Important safety information! Failure to observe these instructions may result in hazardous situations.
Type 2012 Intended use 2 INTENDED USE Non-intended use of the device may be dangerous to people, nearby equipment and the environment. The Type 2012 device is designed to control the flow of liquid and gaseous media. ▶▶ In potentially explosive environments, the device must only be used in accordance with the specifications on the separate Ex-type label. The additional information and safety instructions relating to Ex areas enclosed with the device must be adhered to when deploying the device.
Type 2012 General notes Risk of burns. 4 GENERAL NOTES The device surface can become hot during continuous operation. ▶▶ Do not touch the device with your bare hands. 4.1 Contact addresses General hazardous situations. To prevent injuries, ensure that: ▶▶ The system cannot be activated unintentionally. ▶▶ Installation and maintenance may be performed by authorised technicians only and with the appropriate tools.
Type 2012 Product description 5 PRODUCT DESCRIPTION 6 STRUCTURE AND FUNCTION 5.1 General description 6.1 Structure The 2/2-way globe valve Type 2012 is suitable for liquid and gaseous media. Using neutral gases or air (control media), it controls the flow of water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic solvents and vapour (flow media). One special characteristic of the globe valves are screwed-in seats, which can be replaced when needed. 5.1.
Type 2012 Structure and function 6.2 Function 6.2.2 Depending on the variant, the valve seat is closed in the direction of or against the medium flow. Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) generate the closing force on the swivel plate. A spindle connected to the actuator piston transmits the force. 6.2.
Type 2012 Technical data Flow direction above the seat The valve is closed with the medium flow via spring force (control function A, CFA). Because the medium pressure is above the swivel plate, it helps the valve close and also contributes to sealing the valve seat. The valve opens via pilot pressure. 7 TECHNICAL DATA 7.1 Conformity The Type 2012 globe valve conforms to the EU directives as per the EU Declaration of Conformity. 7.2 WARNING! Risk of injury from pressure surge.

Type 2012 Installation 8.2 Before installation 8.4 Installation position: any, preferably actuator on top. • Ensure that pipelines are in alignment. • Note flow direction. • Remove soiling from pipelines. 8.3 Remove actuator from the valve body (welded connection) Installing valve body WARNING! Risk of injury due to improper installation. ▶▶ Installation may only be performed by qualified and trained personnel. ▶▶ Use an open-end wrench for assembly. ▶▶ Observe tightening torques.

NOTE! Damage to the seat seal or seat contour. ▶▶ The valve must be open when installing the actuator.
Type 2012 Installation 8.7 Pneumatic connection For usage in an aggressive environment, we recommend using a pneumatic hose to drain all free pneumatic ports in a neutral atmosphere. WARNING! Risk of injury due to connecting unsuitable hoses. Hoses that cannot withstand the pressure and temperature range can cause hazardous situations. ▶▶ Only use hoses that are permitted for the specified pressure and temperature range. ▶▶ Note the data sheet information from the hose manufacturers.
Type 2012 Maintenance, cleaning 9 MAINTENANCE, CLEANING 9.1 Safety instructions DANGER! Risk of injury from high pressure in the system. ▶▶ Before loosening lines and valves, turn off the pressure and vent the lines. Risk of injury due to electric shock. ▶▶ Before reaching into the system, switch off the power supply and secure against reactivation. ▶▶ Observe the applicable accident prevention regulations and safety regulations for electrical devices.
Type 2012 Maintenance, cleaning 9.2.1 9.3 Cleaning Commercially available cleaning agents can be used to clean the outside. NOTE! Avoid causing damage with cleaning agents. ▶▶ Before cleaning, check that the cleaning agents are compatible with body materials and seals. Replacing the valve seat Removing actuator from the valve body →→Clamp valve body into a holding device. NOTE! Damage to the seat seal or seat contour. ▶▶ Valve must be open when uninstalling the actuator.
