Overview of Primary Product
V5011N TWO-WAY THREADED GLOBE VALVE
63-2548—3 6
Mounting
The preferred valve mounting position is with the stem
vertical. For steam applications, mount with the stem at a 45
degree angle. Do not mount the valve with the stem more than
90 degrees from the vertical (pointing lower than horizontal).
Scale and foreign material can collect, scoring the stem and
causing packing leakage. Protect the stem from damage due
to bending or scratching.
IMPORTANT
1. Before installing linkage and actuator, make sure that
the valve stem operates freely. Impaired stem
operation can indicate that the body was twisted or
the stem was bent. Either of these conditions can
require valve replacement.
2. Align pipes squarely with valve at each end connection.
3. If the pipes are forced into the valve, the body can
become twisted and improper seating can result.
4. Apply pipe dope sparingly.
5. Be careful to prevent pipe debris, such as chips and
scale, from entering the piping because this material
can lodge in the seat and prevent proper closing.
NOTE: Threading on threaded bodies conform to NPT.
Refer to the table in Fig. 4 for valve pipe sizes and thread
lengths. Fig. 4 also shows two effective methods of holding
the valve and pipe when attaching it. Refer to installation
information furnished with the linkage and motor when
installing these controls.
