Mark 96 Series
Sanitary Pressure Regulators
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.

Sanitary Valves Mark 96 Sanitary Pressure Regulators
Features
• New! Optional Gauge Port
• CRN Registration Number Available
• Soft seat capability for ANSI Class VI shutoff
• No guiding surfaces in the uid below the diaphragm
in the wetted area. ASME BPE compliant
• 100% 316L barstock body – no wetted parts made
from castings
• Self-draining
• Best Accuracy (least droop -set point offset) in the
industry. Ask your rep for a MK96 performance
calculator demonstration
• Clean-in-Place, Steam-in-Place – dome lock pin to
allow CIP/SIP
• Jorlon diaphragm: PTFE based material provides
excellent chemical resistance and extremely long life in
steam service. Far superior to other elastomer or metal
diaphragm materials. Ask your local Representative for
cycle testing information.
Documentation
The following documentation is shipped at no charge:
• Steriow Unicert: Certicate of Compliance for:
- Material, including MTR’s
- Surface Finish
- FDA/USP Class VI
• Traceability:

customer’s set point is P2 = 8 psi, then the actual Cv sizing
should not exceed 2.75Cv. If the customer’s intended set
