Electric pneumatic relays are available in wall- or panel-mount configurations with a range of 24 to 50/60V AC.

RP418 and RP818 electric/pneumatic relays are solenoid valves which open and close the air supply to pneumatic controls. The control input is an on-off line voltage signal to the RP418A-C and 24V AC signal to the RP818A and B.

RP913 diaphragm logic pressure selectors are used in pneumatic control applications to select the highest and/or lowest pressure input from zone thermostats.
