<strong>Bleed</strong> <strong>Valves</strong><br />
RB Series<br />
Introduction<br />
<strong>Bleed</strong> valves can be used on instrument devices such as multi-valve manifolds<br />
or gauge valves to vent signal line pressure to atmosphere before removal of an<br />
instrument or to assist in calibration.<br />
Features<br />
◎ Compact design for easy installation<br />
◎ Hardened stem and tip to extend cycle life<br />
◎ Working pressure up to: 10000 psig (690 bar)<br />
◎ Working temperature: -65° F to 850° F (-54° C to 454°<br />
C)<br />
◎ Variety of end connections<br />
◎ Leak-tight performance testing with Nitrogen or<br />
compressed air for every valve at the rated pressure<br />
(not higher than 6000 psig) to meet the requirement of no visible leak<br />

Caution<br />
When installing a bleed valve, position the vent tube to direct system fluid away from operating personnel. Always open bleed<br />
valves slowly. These valves contain no packing, so some fluid weepage will occur when the valves are opened. Operating personnel<br />
must protect themselves from exposure to system fluids.
