Gas Pressure Regulator Venting – Vent Limiting Devices

When using a vent limiting device, the regulator must be mounted in an upright horizontal position only.

Any orien­tation other than an upright horizontal position will roll the ball check into the closed/limiting position. With the ball check in the closed/limiting position, the regulator may experience high lock-up and a sluggish response time and will not operate as designed.

NOTE: A Maxitrol vent limiting device should only be installed in the Maxitrol regulator that it is certified with.

More infor­mation on Maxitrol’s gas pressure regulators can be found in the latest version of the Gas Pressure Regulator Catalog and Certified Line Pressure Regulator Guidebooks for 2 & 5 PSI natural gas and LP/propane piping systems.
