The Series BV2 is the economical choice for quality, stainless steel ball
valves for use in chemical, petrochemical, pulp and paper, and general
applications. Providing excellent corrosion resistance, the Series BV2
body and tailpiece are constructed of CF8M grade investment cast stainless steel, while the ball and stem are manufactured from 316 SS.
Reinforced TFE seats and body seals provide broad chemical compatibility and bubble tight shutoff to 1000 psi.
The internally loaded blow-out proof stem provides for safety in the event

316 SS Ball and Stem;
304 SS Handle and Locknut.
Max. Pressure: 1000 psi (69 bar) WOG; 150 psi (10.3 bar) SWP.

of overpressure. Full port design allows maximum Cv with minimal pressure drop. Integral actuator mounting pad allows for ease of automation.
Optional locking handle prevents accidental operation. The Series BV2
is available in sizes ranging from 1/4” to 3” NPT.
INSTALLATION
Prior to installation, inspect valve and pipe ends to make sure they are
free from debris. Material trapped inside the valve can cause damage to
the seats and result in leakage. Clean pipe ends and check for proper
threading to prevent damage to valve internals.
Use a PTFE based thread sealant applied to the pipe threads. With valve
in the OPEN position, install pipe. Use a smooth wrench on the hex portion of the valve, not the valve body, to tighten. Use pipe wrenches on
pipe and pipe fittings only.

OPERATION
These valves are bi-directional and can be installed with flow in either
direction. Rotate the handle 90 degrees counterclockwise to open and
90 degrees clockwise to close. Check to make sure the process media
is compatible with the valve materials. See “Physical Data”. Do not
exceed pressure or temperature maximum ratings.
MAINTENANCE
The Series BV2 is a non-repairable valve. The only maintenance
required is the occasional tightening of the packing gland nut. Over time
some leakage may occur through the stem orifice. If this occurs tighten
the packing gland nut approximately 1/4 turn.
