PMX - Maximum differential pressures for PF6 piston actuated valves
* Notes:
1. Maximum differential pressure for saturated steam service is 11.5 bar g and 14.5 bar g for high temperature valve versions.
2. Sanitary clamp connections are limited to PN10 pressure rating.
3. ASME flange connections are limited to ASME 150 pressure rating.
