Delta-Elektrogas PCS Position Indicator Switch

In high-risk industrial combustion environments, knowing the exact state of a safety valve is vital. The PCS series is a mechanical limit switch that mounts directly onto the bottom of Elektrogas solenoid valves. It works by utilizing a micro-switch triggered by the movement of the valve stem. When the valve is fully closed, the switch is activated, sending an electrical signal to the control panel or PLC.

The Delta-Elektrogas PCS Position Indicator Switch is built with a rugged die-cast aluminum housing to withstand the vibrations and thermal stresses common in boiler rooms and industrial furnaces. Its competitive edge lies in its “Proof of Closure” capability, which is a requirement in many international safety standards (such as NFPA or EN). Unlike indirect sensors, the PCS provides direct mechanical confirmation, ensuring that if the valve is stuck open even slightly, the system will detect the discrepancy immediately. This prevents accidental gas leaks during startup or shutdown sequences, significantly reducing the risk of combustion accidents.

Description

The Delta-Elektrogas PCS Position Indicator Switch is a specialized industrial device designed to provide accurate visual and electrical feedback on the operational status of safety solenoid valves. By detecting the closed position of the valve plate, this switch ensures that your gas control system operates with the highest level of safety and monitoring precision.
