Mark 96 Series - Sanitary Pressure Regulator

Brand: Steriflow Valve

The Mark 96 Sanitary Pressure Regulator is designed to regulate pressure in systems requiring the maintenance of sanitary conditions.

The Mark 96 operates by sensing pressure under the diaphragm on the downstream side of the seat.

As the downstream pressure approaches the set point, the force caused by the pressure acting on the diaphragm overcomes the force of the range spring, and the plug begins to move up toward closed.

This reduces the downstream pressure and maintains the set point.

If the pressure underneath the diaphragm begins to fall, the spring forces the plug to move down towards open, to allow the set point to be maintained.
Features
  • No guiding surfaces in the fluid – minimizes particulate generation
  • 100% 316L barstock body – no wetted parts made from castings
  • Best accuracy (least droop – set point offset) in the industry
  • Jorlon diaphragm – lifetime warranty
  • Tri-clamp gauge port
  • Manual CIP pin allows user to look the regulator in full open position during Rinse/CIP/Rinse cycle
