DESCRIPTION
The MO953 and MP953 Pneumatic
Valve
Actuators
(“Actuators”) are used with
V5011
and
V5013
Valves and
can control older steam and water valves via adapters. The
M0953A-D
Actuators are functionally identical to the
MP953A-D
Actuators. Therefore, most of this sheet is
directed to the MP953 Actuators.
MP953A
and B Actuators use a Gradutrol Relay for
positioning, and the
MP953E
and
MP953F
Actuators use a
positive positioner. The relay and the positioner function in
essentially the same way. Positivepositionerretrofitkitsare
available for
MP953A
and B Actuators (see
ACCESSORIES).
APPLICATION
These Actuators operate the
V5011
and
V5013
Valves
and certain other coil, line, and zone valves that
GENERAL
proportionally control steam or hot and cold liquids in
HVAC systems.
