5 Function and operation
5.1 Description of function
L
The valve is opened in direction ’X’ by means of control air, and is closed from top to bottom by
means of spring power without any leakage. Different media fed from the tank or the piping system
ar separated in a leakage–free fashion by means of two, independently acting valve discs with
double seal function. Any leaks occurring due to damaged valve plate seals are drained to the exter-
ior without pressure via the leakage discharge (L).
5.2 Control system and position indicator
Feedback unit -optional-
Optionally, modular valve control head systems can be installed to the actuator for reading and ac-
tuating valve positions. The standard version is a closed system with SPS or ASI-bus switch-on
electronics, and integrated 3/2-way solenoid valves. For tough operating conditions we recommend
employing a high-grade steel cover.
Feedback unit with finger guard -optional-
For the acquisition of the valve positions over inductive initiators (Sensors), a feedback unit is
mounted on the actuation. The enquiry takes place over the position of the piston rod.

NOTICE
Checking the solenoid valves in the control head
Before using the valve for the first time, the function of the solenoid valves in the control head must
be checked.
– Remove the hood on control head.
– Connect the supply air to the control head
– Check the valve functions using the slide switches on the solenoid valve
ðPlease also read the documentation for control heads!
6.1.1 Installation instructions
Fitting position
The valve must be installed vertically with the actuator at the bottom. Liquid must be able to flow
freely from the valve housing and the leakage outlet (L).
6.1.2 General welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To
prevent damage, welding should be undertaken by certified personnel (EN ISO 9606-1). Use the TIG
(Tungsten Inert Gas) welding process.
CAUTION
Damage and injuries due to high temperature supply
To avoid a distortion of the components, all welding parts must be welded to stress-relieved.
Allow all components to cool before assembling.

RECOMMENDATION
Replacement of seals
To achieve optimal maintenance cycles, the following points must be observed!
– When replacement of seals, all product-contacting seals should be replaced.
– Only original spare parts may be installed.
Maintenance interval
The maintenance intervals depend on the operating conditions "temperature, temperature-intervals,
medium, cleaning medium, pressure and opening frequency". We recommend replacing the seals1-
year cycle. The user, however should establish appropriate maintenance intervals according to the
condition of the seals.

6.3 Cleaning
Cleaning
The valve housing is cleaned with the pipe cleaning system when the valve is closed. At the same
time, the leakage chamber with the valve shaft is cleaned by cycling the valve disk V2. When clean-
ing the tank, it is possible to clean the leakage chamber when the valve is closed and the valve disk
V1 is cycled. When the valve is open, the valve housing is cleaned via the CIP return line.
