Delta-Elektrogas PCS Position Indicator Switch: The PCS is a mechanically activated switch for monitoring the position of the valve plate. This device can be fitted to the Elektrogas aluminum valves series VMR, VML, VMM, VMH, EVRM-NA, EVRM-6NA, EVRM-NC, and EVRM-6NC to check the closed position of the plate. It can be fitted to the N.O. vent valve VMRNA to check the open position of the plate. It can be also fitted to solenoid actuators (SR – SL – ST) to check the open/closed position of the butterfly valve (VF – VFH).
It is designed in accordance with norm EN161 to detect the closed status. The compact, robust and functional design permits a simple and quick installation even on the field. It is essentially maintenance-free. Available in ATEX ex-proof version.
Features
The PCS is a mechanically activated switch for monitoring the position of the valve plate.
This device can be fitted to the Elektrogas aluminum valves series VMR, VML, VMM, VMH,
EVRM-NA, EVRM-6NA, EVRM-NC, EVRM-6NC to check the closed position of the plate.
It can be fitted to the N.O. vent valve VMRNA to check the open position of the plate.
It can be also fitted to solenoid actuators (SR – SL – ST) to check the open/closed position of the
butterfly valve (VF – VFH).
Applications
PCS is available with working pressure 500 mbar or 6 bar.
An adapting rod is necessary to fit the switch to an Elektrogas valve or actuator. The switch is
supplied with the rod already mounted, to make installation easier.
The switch can be rotated at 360° on the rod axis.
Electrical connection with ISO4400 plug.
It is suitable for air and non-aggressive gases (families 1-2-3 EN437). Special versions are
available for use with aggressive gases.
The compact, robust and functional design permits a simple and quick installation, and it is
essentially maintenance-free.
All components are designed to withstand mechanical, thermal, and chemical stresses present
in a typical installation.
The device can be provided in Ex-proof execution, for use in Zones 2 and 22, according to
2014/34/UE Directive (ATEX).
Switches are 100% tested for seal and functioning.
