General Description
Functional Description and Hydraulic Symbol
Technical Specification
Temperature Compensating Block for indication of end positions
(VPI-V or VPI-E). The TC-Block allows the expansion/contraction
of the oil in the system caused by major temperature and
pressure variations without influencing the end stops and the
switch functions of the indicator.
The Block is provided with Cetop-3 connection for mounting
of pilot valve. The combination of the VPI indicator and the TC-
Block can be used for all DKMS-actuators and is used at on/off
controls .
The function of the TC-Block is to allow the oil only to flow through
the VPI in the required direction (locks and acknowledges the el.
on/off signal). The undesired contra-flow is bypassing the VPI,
thus avoiding an electrical signal failure with resulting “alarm
signal”. This undesired oil flow is caused by the temperature
expansion/contraction of the oil and also by a fluctuating
pressure in the system at an on/off-operated actuator.
Note!
The TC-Block is always to be used together with a 4/2-way
control valve.
