Multiple fan coil unit installation
GLOBE
VALVE
** All three fan coil units to serve one area with a common
thermostat. When temperature has reached set point,
thermostat will send signal to 3-way valve to divert
water away.
GUIDELINES FOR VALVE AND FITTING INSTALLATION
a. Gate valves (shut-off) are installed in the entering and leaving
piping to the chiller and fan coil unit. This is to permit servicing
and replacement of the equipment without draining the
system. A globe valve may be used to serve as one of the
shut-off valve and in addition to balance the rate.
b. Valves and fittings using threaded or welded joints will require
unions to permit easy removal for servicing or replacement.
Unions are usually located between each gate valve and
the equipment. Unions are also place before and after the
control valve, and in the branch of the 3-way valve.
If flange joints are used, the need for unions is eliminated.
