Introduction

The 67C Series high-pressure regulators meet a
variety of applications in liquid or vapor service.
The compact body design makes the 67C Series
particularly useful in installations with space limitations.

The basic 67C Series regulator comes equipped
with a wrench or handwheel adjustment (67CW or
67CH Series). The highly accurate 67CD Series
eliminates the need for a pressure gauge on portable
applications by using calibrated scales on the spring
case, allowing visual adjustment of outlet pressure.
The non-adjustable 67CN Series provides a tamper­resistant spring case and one of three xed setpoints:
10, 15, or 20 psi (0,69; 1,0; or 1,4 bar).

The 67C Series carries a UL listing as a high-pressure,
non-relief regulator. This series contains brass
materials that are not compatible with anhydrous
ammonia service.
