Product Description:
Transfer Valve 78-80S & 08-80S | Masoneilan 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.
By plugging the side port of the Transfer Valve to make it as two way port, the model can be used as lockup valve. Lockup valve is used as a safety device to hold control valve at the actuated position when outage occurred in air supply, by closing air supply system of pneumatic control valve until supply air pressure returns to original pressure.
