Neles™ Capping Valves enhance process reliability and safety.

Neles™ Capping Valves enhance process reliability, safety, and efficiency. The Neles Series PZ Capping Valve provides an automated solution for opening and closing batch digesters for chip fill. This capping valve significantly improves the efficiency of the chip fill process and enhances operator safety.

The Neles PZ Capping Valve enhances plant efficiency by reducing filling time through automated valve open and close operations. These valves ensure secure operation and full automation of the digester chip fill process, leading to increased productivity and improved safety for process operators. Additionally, the valve offers a fast return on investment due to its boost in productivity and minimal need for modifications to existing digesters.

Metal-to-Metal Seating: Provides long-lasting tightness and reduces maintenance costs. Compact Safety Interlocks: The PZ capping valve incorporates safety interlocks using two pressure sensors mounted on the valve body to prevent unintentional operation when the digester is pressurized. Custom-Made Flange: The valve’s lower flange is custom-designed to match the digester's top flange, ensuring easy installation on existing digester vessels.
