Valves

The By-Pass-Valve:
The by pass valve is attached to the end of the HP-pump delivery manifold. Its main function is to circulate water back to the inlet pipe system or out to the delivery system and spray nozzles.

The valve contains three valves: the by-pass valve, the over pressure valve and
the check valve. Each valve has a specific task. Inside the directional valve the
water is directed by the by-pass valve, it is controlled pneumatically and actuates
its function hydraulically.

As a relief precaution in situations of over-pressure, the relief valve can
automatically relieve the hydraulic force of the by-pass valve by reducing
the overpressure. As the delivery water exits the directional valve, it passes
through the check valve. The check valve keeps the water from recirculating
backwards into the system. The valve regulates the delivery of high-pressure
water at the pump and descaling equipment.

The Direction Valve:
Direction 2/2 or 3/2 way valves are on-off valves pilot operated in stainless steel.
