Masoneilan Model 78-80S & 08-80S Transfer Valves

1.Descreption

    The Model 78-80S is a transfer valve combining a pilot valve of the floating ball type and three-port valve into one unit and is a standard-capacity three-way transfer valve of a set pressure regulating type. The other model 08-80S, is the same as the 78-80S except that a pilot valve is not combined and is the so-called three-way transfer valve. If several 78-80S are needed, one 78-80S can be installed, connecting 08-80Ss to it by mating the pilot outlet pressure (“SIG.OUT”) on the 78-80S to “SIG” on the 08-80S to simplify piping and achieve transfer.
