Torkval P-12 Adjustable Resistance Valve

Linear threshold mechanism with internal elastomer diaphragm
The Torkval P-12 valve functions as an adjustable flow restrictor requiring a specific differential pressure to allow airflow. It is engineered for integration into exercise breathing circuits where a known, consistent opening threshold is required. Its external micrometric thread allows you to set internal spring tension with millimeter accuracy. The precision elastomer base ensures complete airtightness at rest, preventing any leakage before reaching the designated operating value.

Reliability of the elastic seal

Issues with common rigid-disc valves

Many conventional components use hard gaskets that develop microscopic leaks or vibration noise. This causes erratic readings and continuous pressure drops.

Sealing via calibrated flexible membrane

The combination of precision elastomer and 304 stainless steel ensures instant, silent contact. The threshold is maintained consistently across each cycle without unwanted flutter.

Buyer feedback

★★★★★

"The thread allows adjusting the level quite accurately. The inner disc seals without letting air through before the set point."

Martín G. Customer
★★★★★

"The quality of the materials is noticeable, with no play or squeaking. It fits my usual flexible tubing perfectly."

Beatriz S. Customer
This product is sold as a mechanical resistance accessory for general breathing activities. It is not intended for the diagnosis or therapeutic treatment of medical conditions.
