General Information
The Model BVL, lever type bleeder valve, is for use as a test valve for
pressure operated devices on wet pipe sprinkler systems that have excess
pressure, or dry pipe sprinkler systems.
The BVL should be installed in-line with the pressure device. It provides
a convenient means for removal or testing the pressure actuated device
without affecting the pressure in the system. Closing the valve (moving
the valve handle perpendicular to the 1/2" pipeline) shuts off the water
or air from the supply and opens a small orifice (pin-hole) to exhaust the
pressure between the valve and the pressure device. This should provide
a low pressure actuation of the pressure device, testing its operation.
Installation
The BVL should be installed in-line to the alarm or supervisory device
with the “PD” (Potter Device) stamp, or with the arrow pointing toward
the alarm or supervisory device that is to be tested.
