Valve Installation
Threaded Valve bodies
Line up the pipes squarely with the valve at each end. If the
pipes are forced into the valve, the body may become twisted
and improper seating will result. Prevent pipe chips, scale,
and dirt from entering the piping since they may lodge in the
seat and prevent proper closing. Apply a vise or wrench to the
valve (see Fig. 9).

Fig. 8. Three-way mixing valve operation–coil bypass.
Three-way valves maintain constant flow in the piping.
As the temperature requirements change, the
volume of the fluid in the coil varies.

Flanged Valve Bodies
The valve flanges are flat faced with a smooth finish.
Companion flanges must be of the same specifications.
Mounting bolts must be long enough to allow nuts to utilize
the full length of the nut threads.
The bolts should be approximately 1/8 in. (3 mm) smaller than
the diameter of the bolt hole to allow clearance for installing.
To prevent leakage, use a gasket material recommended for
the medium to be handled.
