Potter BVL Lever Type Bleeder Valve Owner's manual

  • I have reviewed the datasheet for the Potter BVL Bleeder Valve. This document outlines its use as a test valve for pressure-operated devices in sprinkler systems. It details the installation process and provides key features such as its bronze body, zinc-plated handle, and 1/2" NPT connections. I am ready to answer any questions you have about this valve.
  • What is the BVL valve used for?
    How does the BVL valve work?
    Where should the BVL valve be installed?

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 ori ce (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.
