Description
P47 Series Steam Pressure Limit Control - sight-set steam pressure control for high limit or operating control applications.
The P47 Controls are available with single-pole, single-throw (SPST), double-pole, single-throw (DPST), or four-wire, two-circuit contacts for line voltage or low voltage. The pressure connector is 1/4 in. external NPT (0 to 15 psi only) or 1/4 in. internal NPT (for all other ranges).
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.
Features
* Long-life contact structure with high contact force
* Easy-to-adjust single sight set scales show both cut-in and cut-out settings
Applications
* High limit control on steam heating systems
* Operating control on steam, water, air or noncombustible gas systems that do not harm iron or copper
* Blower interlock on steam unit heaters (close-on-rise models)
Accessory (OEM): The Part No. TBG16A-600 Siphon is supplied with all controls except models with 0 to 15 psi range.
