Basic safety instructions
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not take into account any unforeseen circumstances and events which occur
during installation, operation and maintenance.
The operator is responsible for observing the location-specific safety regulations, also with reference to the
personnel.
DANGER!
Risk of injury from high pressure and discharge of medium.
▶ Before working on the device or system, switch off the pressure. Vent or drain lines.
DANGER!
Electric shock due to installed electrical component.
▶ Before working on the device or system, switch off the power supply. Secure against reactivation.
▶ Observe the applicable accident prevention and safety regulations for electrical devices.
WARNING!
Risk of injury when opening the actuator.
The actuator contains a spring under tension. When the actuator is opened, the spring will jump out and
may cause injuries.
▶ Do not open the actuator.
WARNING!
Risk of injury due to moving parts.
▶ Do not reach into openings in the device.
WARNING!
Danger of burns and risk of fire.
Quickly switching actuators or hot medium may cause the surface of the device to become hot.
▶ Only touch the device while wearing protective gloves.
▶ Keep the device away from highly flammable substances and media.
WARNING!
Danger due to loud noises.
Depending on the usage conditions, the device may generate loud noises. Detailed information on the
probability of loud noises is available from the respective sales department.
▶ Wear hearing protection when in the vicinity of the device.
WARNING!
Discharge of medium if packing gland worn.
▶ If media are hazardous, safeguard the environment around the discharge point.

Type 2000
Basic safety instructions
To prevent injuries, observe the following:
▶ Secure device or plant to prevent unintentional activation.
▶ Only trained technicians may perform installation and maintenance work.
▶ Perform installation and maintenance with suitable tools only.
▶ Heavy equipment must only be transported, assembled, installed or dismantled with the help of a
second person as appropriate and using suitable apparatus.
▶ Following interruption of the process, ensure that the process is restarted in a controlled manner.
Observe sequence:
1. Apply electrical or pneumatic supply.
2. Charge with medium.
▶ Do not make any changes to the device and do not subject it to mechanical stress.
▶ Feed only those media, which are listed in the chapter "Technical data", into the medium ports.
▶ Operate the device only in perfect state and in consideration of the operating instructions.
▶ For applications planning and operation of the device, observe the plant-specific safety regulations.
▶ Observe the general rules of technology.
▶ The plant owner is responsible for the safe operation and handling of the plant.
To protect the environment, observe the following:
▶ The pilot exhaust air of the device may be contaminated by lubricants.

Product description
5 PRODUCT DESCRIPTION
The device is specially optimised for decentralised process automation and meets all the relevant requirements, even under difficult usage conditions.
Its design enables the easy integration of automation modules in all extension stages, whether they are
electrical/optical position feedback, pneumatic control units, or even an integrated fieldbus interface. Long
service life and high tightness are achieved by the tried and tested self-adjusting packing gland. The system, consisting of valve and automation module is distinguished by a compact and sleek design, integrated
pilot air ducts, a high chemical resistance, the degrees of protection IP65 or IP67 as well as the NEMA protection class 4X.
The device uses neutral gases or air to control the flow rate of liquid or gaseous media, such as water, alcohol, oil, fuel, saline solution, hydraulic fluid, lye, organic solvent or vapour.
5.1 Features
▪ Actuator can be rotated steplessly by 360°
▪ Valve body made of stainless steel with threaded connection, clamp connection or welded connection
▪ Easy integration of automation modules
▪ High chemical resistance
▪ High tightness and long service life due to self-adjusting packing gland
▪ High flow values through flow rate-optimised valve body made of stainless steel
▪ High seat tightness by swivel plate
▪ Maintenance-free under normal conditions
5.2 Structure and function
The angle seat valve consists of a pneumatically actuated piston actuator and a 2-way valve body. The actuator is made of PA or PPS. The proven, self-adjusting packing gland guarantees a high degree of tightness. Valve bodies made of stainless steel or red bronze 1.
Depending on the variant, the valve seat is connected in the direction of or against the medium flow. Spring
force (SFA) or pneumatic pilot pressure (SFB and SFI) generate the closing force on the swivel plate. A
spindle connected to the actuator piston transmits the force.
