BRASS BALL VALVES 2-WAY BALL VALVE The ball valve can be mounted in both flow directions, without distinction. OPEN valve CLOSED valve OPENING actuator CLOSING actuator 3 WAY DIVERTER/MIXER BALL VALVE The 3-way version of Diamant which is therefore always open. PRO is available with two different balls. In both cases, one of the holes is positioned on the common way, DIVERTER / MIXER - 3 HOLES • C = COMMON WAY MIXER/DIVERTER BALL VALVE (3-HOLE BALL) The MIXER/DIVERTER ball valve has a 3-hole sphere with one hole pointed towards the common way C (always open) and two more holes which are...

BRASS BALL VALVES 3-WAY DIVERTER BALL VALVES In Diamant PRO valves, the HORIZONTAL 3-way version is available with a T-ball or L-ball; in both cases, they are used to allow a DEVIATION. Both ball valves close one way and, at the same time, start opening of the other one:f or a short period of time, during the operating phase, all three ways are in communication with each other. Despite the condition described above, however, it is not possible to carry out a mixing adjustment by means of this type of valve because of the limited dimensions of the sections created.

BRASS BALL VALVES CONNECTION TO THE BALL VALVE DIRECT CONNECTION TO THE BALL VALVE The direct connection of the Diamant PRO with COMPARATO connection can only be made on the ball valve with COMPARATO connection. For the direct coupling to ISO 5211 connection ball valve see the PRO Range data sheet. Diamant PRO COMPARATO connection Diamant PRO with COMPARATO connection Ball valve CONNECTION TO THE BALL VALVE WITH A SPACER The ball valves fitted with a spacer (both with direct rod and manual opening) must be motorized with a Diamant nection, even if the ball valve has an ISO 5211 port....
