Pneumatic gauge and pressure control device and pneumatic system including same

A pneumatic gauge and pressure control device comprising a first body, a pneumatic gauge that is fixed to said first body, and a second body that is manually rotatable relative to said first body and said pneumatic gauge about an axis of rotation from a neutral position to either:

• (i) a fill position in which compressed air is communicated from an associated compressed air source into an associated destination system;
• (ii) a vent position in which compressed air is vented from the associated destination system,
• wherein said second body rotates in a first angular direction relative to said first body and said pneumatic gauge from said neutral position to said fill position and rotates in a second angular direction relative to said first body and said pneumatic gauge from said neutral position to said vent position, and
• wherein said second body activates a first switch when rotated in said first angular direction to initiate communication of compressed air into the associated destination system and activates a second switch when rotated in said second angular direction to initiate venting of compressed air from said destination system.
