PPVEX 3/2-way, Piezo-pilot, overlapping, normally closed (NC) poppet valve

By Dini Argeo

The PPVEX is an ATEX-certified 3/2-way, normally closed piezo-pilot poppet valve for Zone 1 gas hazardous areas. It is directly compatible with the digital outputs of Dini Argeo DFWIECEX ATEX weighing indicators and carries intrinsic safety (Ex ia) certification to II 1G Ex ia IIC T4/T5/T6 Ga, covering IIC gas group and EPL Ga — the highest equipment protection level for gas environments.

PPVEX — ATEX-Certified 3/2-Way Piezo-Pilot Poppet Valve for Hazardous Areas

The PPVEX is an intrinsically safe, 3/2-way piezo-pilot operated poppet valve designed for use in ATEX Zone 1 gas hazardous environments. Normally closed (NC) in its default state, it is specifically engineered for compatibility with the digital outputs of Dini Argeo DFWIECEX ATEX weighing indicators, enabling precise pneumatic control directly from an intrinsically safe weighing system without the need for additional safety interfaces.

Key Features

  • 3/2-way, normally closed (NC) poppet valve — safe-state closed for reliable process control in hazardous areas.
  • Piezo-pilot actuation with overlapping design for smooth, reliable switching.
  • Directly compatible with DFWIECEX digital outputs — no additional safety barriers required.
  • ATEX certified for Zone 1 gas environments: II 1G Ex ia IIC T4/T5/T6 Ga.
  • Intrinsic safety (Ex ia) protection mode — suitable for the most demanding Zone 1 gas applications.
  • Temperature class options: T4, T5, or T6 to suit process requirements.
  • Conforms to the ATEX Directive.
