STEAM PRESSURE CONTROL; PRESSURE CONTROL STEAM OR WATER; SPST; 50/240#; MANUAL RESET

P47 steam pressure controls are designed for high limit or operating control applications. A typical use is as a limit control on steam heating systems. Models that close on a pressure increase are used on steam unit heaters to avoid blower operation when steam pressure is below the point required for adequate heating. The P47 can be used with steam, water, air, or noncombustible gases that do not harm iron or copper.
