Page 9: Operating Parameters
Waukesha Cherry-Burrell Introduction Operating Parameters Temperature Range: Recommended operating temperature is determined by the material used for the seals. No special precautions are required for applications within a temperature range of 32°F to 180°F (0°C to 82°C). For applications above 190°F (88°C), clearances can be affected by excessive thermal expansion when the valve is installed in compact fabrications or manifolds. -
Page 10: Installation
Installation Waukesha Cherry-Burrell Installation CAUTION: When installing the valve, ensure that no foreign materials (e.g. tools, screws, welding wire, lubricants, cloths, etc.) are enclosed in the system. Location The valve must be in a vertical position to ensure that the vent/drain outlet system functions properly. -
Page 11: Pipeline Support
Waukesha Cherry-Burrell Installation Pipeline Support Install adequate supports to prevent strain on the fittings, valves, and equipment connections. Install supports at least every 10 feet (3 meters) on straight runs of piping (Figure 2, item C). Install supports on both sides of the valves as close as possible to the connections (Figure 2, item D). -
Page 12: Connecting Flush Supply Line (Optional)
Installation Waukesha Cherry-Burrell Connecting Flush Supply Connect the cavity cleaning supply to a suitable water supply to flush the vent/ Line (Optional) drain (Figure 4) during operation of the processing system. The flush supply line can be connected to a pipe system by 1/4" (6 mm) rigid or flexible poly tubing. -
Page 13: Operation
Waukesha Cherry-Burrell Operation Operation All functions of mix proof valves are pneumatically controlled using a 72 to 100 psi (4.9 to 6.9 bar) clean air supply. The valve contains a large and small spring in the valve actuator. The springs hold the valve seats in the closed position. -
Page 14: Automatic Fail-Safe System
W75RS PMO valves are spring-to-closed fail-safe into the blocked position. Waukesha Cherry-Burrell does not offer control systems, only the PMO double seat valve. To determine the integrity of fail-safe control interlocks, see “Positive Fail-Safe Detection Test”... -
