The Style ‘R’ valve is intended for installation in low-pressure steam systems such as preheaters, laundry equipment and galley equipment. The inlet pressure rating of the Style ‘R’ valve is 150 PSIG, and the outlet set pressure is adjustable from 15 to 135 PSIG. The valve requires at least a 15 PSI pressure difference between steam supply pressure and maximum regulated pressure. It can be adjusted to limit maximum output pressure to any value from 15 PSI below supply pressure down to 5 PSI gauge pressure.
