Waukesha Valves- W68 Pressure Overview
WAUKESHA VALVES – W68/W88 SERIES – PRESSURE CONTROL VALVE
“Pressure Control Valve- Operating Parameters”
The 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. Valve bodies have thicker cross-sections than tubing, but thermal expansion can affect clearances in interconnecting piping sections.
If operating below 32°F (0°C):
•Control air must have an appropriately low dew point.
•Valve stems must be protected from icing to ensure long working life for valve stem seals.
Solenoid valves may not be used in the control module in room environments below 32°F (0°C) and over 140°F (60°C), as function cannot be guaranteed.
