BEFORE INSTALLATION
This normally-open, single-seated, straight-through,
pneumatic valve provides two-position or proportional control
of two-pipe hot water or steam systems.
The valve can be installed in any position. The direction of
flow must be in the same direction as the arrow cast on the
valve body.
Refer to Fig. 1 for dimensions to determine the space required
for proper installation. Be sure to allow enough clearance
around the actuator top for servicing after installation.
