Water Temperature Max. 70°C

Construction Characteristics
• Casing of Brass.
• Interchangeable Stainless Steel Valve bodies.
• Connections for Manometer, Pressure Switch and Flow Switch.

Operation
The whole discharge must be guided through the valve. Should the actual operating pressure exceed the adjusted operating pressure, the valve then acts as a pressure regulator. The valve switches to pressure-free bypass operation when the spray gun shuts off and the spray pressure between gun and valve remains idle.
The valve can be operated together with several spray guns. It is also possible to connect several pumps to one common discharge line.

Safety Instructions
Observe direction of flow. The bypass must under no circumstances be closed or fitted with any shut- off device.
Continuous bypass operation without re- leasing the water can cause the liquid to heat up which in turn could damage the unit and endanger persons.
Possible preventive measures:
1.) Limit the bypass duration (max. temperature 70°C); the duration is to be calculated by the operator and in conjunction with the operating conditions.
2.) Use fittings (e.g. thermo valve on water inlet) to avoid heat increase.
