This valve assembly is of a design used by other manufactures too, though usually made of brass, such as in the Rocket and Scala equipment.
This Ascaso version is nickel-plated and includes an expansion valve, a fitting to connect to the water mains, out to the pump pressure gauge, a third for the connection to the flowmeter, another for a one-way valve and a flat flange that accepts a two-way solenoid (not included).
