How they work
A spring closes the valve when pressure equalises or rises on the spring side. The medium flows in one direction only.
Two models
RUF3
Marked profile seals, intermediate flange — easy removal from the line. Vertical or horizontal installation.
DN 25 – DN 150 · ISO 1″ – 4″
VPN
Simple design with few parts — a cost-effective alternative to RUF3. EPDM or Viton seals.
DN 25 – DN 100 · ISO 1″ – 4″
