The Series BV2MB is an economical hand lever ball valve for commercial and general industrial use. The Series BV2MB is perfect for water
shutoff applications. Valve body, body cap, and ball are made of quality
brass. Seats and stem packing are constructed of TFE for long lasting
service. Blowout-proof stem provides safety in the event of overpressure.
Full port design allows for maximum Cv and minimal pressure drop.
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.

MAINTENANCE
The Series BV2MB is a non-repairable valve. The only maintenance
required is the occasional tightening of the packing gland nut.
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 “Specifications”. Do not
exceed pressure or temperature maximum ratings.
