The SR Series provides an economical means of flame staging where infinite modulation is not required. Turn down on low fire is from 25% to 75% of high fire — flow rates to 1,000 CFH.

When vented to the outdoors the 325 Series is suitable for multi-poise mounting. When using the vent limiting device, the regulator (325-3, 325-5A) must be mounted in a horizontal upright position.

The R & RS regulators are for main burner and pilot load applications. Ideal for use with infrared heaters and pilot lines on large industrial heaters and bakers. May also be used in residential applications.

The 220 Series, utilizing a servo-operated design rather than the more conventional spring-loaded design, delivers higher outlet pressure than spring loaded models.

The poppet model RV Series is designed primarily for main burner and pilot load applications. They are available from 1/8" to 3/4" pipe size and rated for up to 1/2 psi (35 mbar).
