The Prism


  The Prism Series, designed for corrosive process environments, attaches directly to
Sanitary Diaphragm and Angle Valves.  This rugged, feature-rich platform, offers a full
array of communication and switching options as well as discrete integral pneumatic
control for single-acting valve actuator operation.


1 The Prism may be washed down and temporarily
submersed with no adverse affects. It is rated
NEMA 4, 4x, and 6. It may be used in Div. 2/Zone
2 areas (Nonincendive) or Div.1/Zones 0 & 1
(Intrinsically Safe) hazardous applications.

2 Enclosure features high strength polycarbonate
with excellent corrosion resistance and exceptional temperature stability.

3 Visual electronic and mechanical position indication
confirm valve and switch status for added safety.

4 Solid state proximity sensors monitor Open/Closed
discrete valve position with precision and reliability.

5 Integral pneumatic valve is isolated from environmental contamination, offers high tolerance to dirty air and
enables rapid valve operation.

6 Solenoid options available for 120VAC and 24VDC. Select Piezo option for bus powered
FOUNDATION Fieldbus Applications.

7 Self Adjusting triggering system provides consistent Open and Closed indication even with
diaphragm compression. No resetting is required.

8 Manual override enables valve operation without electrically energizing.

9 Dual module system seals all position sensing, communication and control electronics in a
compact vibration proof package.

10 NPT port connections are stainless steel reinforced for long life sealing under high torque
stress conditions.

11 Water proof quick connectors, compression fittings or conduit connections are available for
convenient, reliable attachment to plant electrical systems.

12 Stainless steel adaptor system locks Prism securely to valve actuator and provides stability
for shaft interface.
