The ADCA RP45TW series pressure reducing station consists of two standard RP45 valves installed in parallel. This system is particularly recommended for installations where a single valve cannot reach the maximum required flow rate or when the consumption variation is significant, being prudent to install two smaller valves instead of a single one in order to avoid oversizing. This system is also recommended when it is vital that the steam supply is not interrupted.
