Application:<\/strong>
\nDesigned to reduce first stage pressure of 5 to 20 PSIG down to burner pressure, normally 11\u201d w.c. Ideal for medium commercial installations, multiple cylinder installations and normal domestic loads.<\/p>\n

Features:<\/strong>
\n\u2022 Large vent helps prevent blockage and has \u00be” F.NPT for vent piping.
\n\u2022 With 15 PSIG inlet pressure, regulator is designed to not pass more than 2 PSIG with the seat disc removed.
\n\u2022 Incorporates integral relief valves.
\n\u2022 Replaceable valve orifice and valve seat disc.
\n\u2022 Straight line valve closure reduces wear on seat disc.
\n\u2022 Unique bonnet vent profile minimizes vent freeze over when properly installed.
\n\u2022 Large molded diaphragm is extra sensitive to pressure changes.
\n\u2022 Built in pressure tap has plugged 1\u20448″ F.NPT outlet. Plug can be removed with a 3\u204416″ hex allen wrench.
