Tormene Gas Pressure Regulators


It is designed for use in transmission and distribution networks, as well as commercial and industrial supplies.


The ALPHARD P/AP is a pilot-operated regulator, type FTC (fail to close), or FTO (fail to open) available with or without an integrated safety shut-off device. The pilot and feeder system supplies constant outlet pressure when the inlet pressure varies and/or the flow rate varies.

  • Accurate control
  • Easy maintenance
  • Monitor application
  • DVGW approval
  • CE approval
