Flow Pattern
• Carbon Steel 150/300 ANSI Rated Bodies
• Equal Percentage Flow Characteristic
• Dual Body rating on 1”, 1½” & 2” (ANSI 150/300)
• ASME B16.10 Face to Face Dimensions
• ANSI Class IV Shut-off
• 250PSI 400 degree rated
• Field replaceable seat
• Maintenance free spring loaded packing
Ideal for replacing globe valves where high
close off is required.
NOTE: Industrial ball valves have serviceable components similar to globe
valves, proper maintenance of these parts will ensure longer in service
life for the valves. The seats of these valves will require replacement at
an interval consistent with the number of full cycles the valve has been
operated, or as field condition dictates.

Valve must be installed with the Ball in closed position
Piping/Mounting Orientation
Assembly can be mounted horizontally or vertically for water applications. For steam applications the valve can be mounted vertically but if mounted horizontally the
valve must be 90° off center of the pipe.
Do not install with actuator below pipe.

3.
4.
1. Remove valve from pipe
2. Remove 2 cap retaining washers (1)
3. Using 2 wrenches/flat-head screwdrivers, pry cap assembly (2) out of
valve
4. Rotate valve to fully open position
5. Using hands, pull seat (3) out of the valve
6. Replace seat and reverse procedure to reassemble
7. Reinstall valve per installation instructions
Valve must be in the closed position for installation.
Figure 1 illustrates a flanged valve installation.
Use hex bolts & nuts to secure valve to flange.
Ensure proper gaskets are used between the valve flange and pipe
flange.
5. Tighten bolts & nuts in alternating opposite sides until completely
tightened. Please see torque requirements below. Torque wrench is
required.
