Valmet Oyj’s trade press release July 9, 2025, at 9:30 a.m. EEST

Valmet launches Pulp Filtrate Extractor for more precision in pH measurement. It provides the highest availability and most accurate process temperature and measurement conditions on the market, ensuring pH and residual chemical accuracy.

The Pulp Filtrate Extractor is a natural upgrade from previous generations, including Valmet Piston and Valmet Screen Extractor. The new extractor enables pulp makers to achieve precise measurements in pulp filtrate by improving measurement conditions and increasing uptime. It offers up to 70 percent greater flow than competing solutions, ensuring higher filtrate temperatures and better conditions for exact pH measurements.

In addition, due to its self-cleaning benefits, maintenance requirements are significantly reduced, while wearing parts are purposely designed to be easily replaced without special tools.

“Our long experience with pulp filtrate sampling has led to a breakthrough in sampling technology. Valmet Pulp Filtrate Extractor provides a solid basis for advanced process controls in the fiberline,” says Matti Selkälä, Business Manager, Pulp and Energy Analyzers, Automation Solutions, Valmet.
