0 to 15 psig Steam Pressure Limit Control Diff: 2 to 8 psig (Johnson Controls)


The P47 controls are available with SPST, DPST, or 4-wire, two-circuit contacts for line voltage or low voltage. The pressure connector is 1/4 in. male NPT (0-15 psig only) or 1/4 in. female NPT (for all other ranges).


• Long-life contact structure with high contact force

• Easy-to-adjust single sight set scales show both cut-in and cut-out settings


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.


The Part No. TBG16A-600R Siphon is supplied with all controls except models with 0 to 15 psig range.
