PPVIECEX 3/2-way, Piezo-pilot, superposed, normally closed (NC) poppet valve

By Dini Argeo

The PPVIECEX is an ATEX and IECEx certified 3/2-way, normally closed piezo-pilot poppet valve with superposed actuation, for Zone 1 gas and Zone 21 dust hazardous areas. Directly compatible with Dini Argeo DFWIECEX digital outputs, it carries intrinsic safety (Ex ia) certification for gas (II 1G Ex ia IIC T6 or T4 Ga) and dust (II 1D Ex ia IIIC T135 °C), covering the most stringent IIC gas and IIIC dust groups.

Product Information

PPVIECEX — ATEX & IECEx Certified 3/2-Way Piezo-Pilot Poppet Valve for Gas & Dust Hazardous Areas

The PPVIECEX is an intrinsically safe, 3/2-way piezo-pilot operated poppet valve with superposed actuation, designed for use in both gas (Zone 1) and dust (Zone 21) hazardous environments. Normally closed (NC) in its default state, it is directly compatible with the digital outputs of Dini Argeo DFWIECEX ATEX weighing indicators, enabling precise pneumatic control from an intrinsically safe weighing system without additional safety interfaces. Carrying both ATEX and IECEx certification, the PPVIECEX is suited to international hazardous area installations.

Key Features

  • 3/2-way, normally closed (NC) poppet valve — safe-state closed for reliable process control in hazardous areas.
