  • Pilot control relay valve apparatus
    Patent number: 4559970
    Abstract: An improved pilot control relay valve is disclosed to monitor pressure conditions in a pressurized system and to cause the system to shut down in response to detection of operating pressures excessive of an acceptable pressure range. Accurate monitoring is provided for by dual-piston action, with one of the pistons actuating a visual indicator mounted on the slide valve of the control relay valve, and with the second piston coaxially mounted within the first piston.
