Robertshaw 83939-D Series Manual

GENERAL DESCRIPTION
The 83939-D Series is a high capacity, two-position,
four-ported,
diaphragm-actuated relay. This relay will supply
pressure from Port S to Port C when the actuating
diaphragm is pressurized. When the relay is in the
closed position, it will vent downstream pressure.
These relays have no transient position which allows
Ports S, C, and V to all be connected; i.e., before Ports
S and C are connected, Port V will be closed, and
likewise, before Ports V and C are connected, Port S
will be closed.
