Quick-Disconnect Bleeder Valve attaches to 1/4 in. (6.35 mm) female National Pipe Thread (NPT) outlets, releasing trapped air or debris from water-based systems. Bleeder valves are an important part of a complete cap gauge for static pressure tests of fire hoses, fire hydrants, and other water-based systems. This bleeder includes two ball valves for complete control over the distribution of pressure.
This Quick-Disconnect Bleeder Valve directs water to one of two 1/4 in. female NPT (FNPT) outlets: the bleeder port or the gauge port. The durable brass quick-disconnect fitting at the gauge port facilitates quick and easy removal of the pressure gauge (sold separately) from the bleeder valve. Made by Parker Hannafin, a global manufacturer of high-quality couplings, this quick-disconnect fitting protects pressure gauges against unnecessary wear, promoting long life and long-lasting calibration.
To conduct static pressure tests using this Quick-Disconnect Bleeder Valve, connect it, along with an appropriate gauge and test cap, to the hydrant or another outlet. With the bleeder ball valve open, begin flowing water. After purging air and debris, close the bleeder ball valve and open the valve leading to the pressure gauge. When testing concludes, protect your gauge against over pressurization by re-opening the bleeder valve before shutting off the supply of water.
