Series LFBP30 Lead Free* Diaphragm Operated Bypass
Relief Valves regulate liquid pressure as supplied by a posi-
tive pressure pump. These relief valves protect equipment
by opening at desired setting and allowing excess volume to
be bypassed back to source. They feature Lead Free cast
copper silicon alloy body construction, sensitive rubber dia-
phragms, and Buna-N discs.
The tee handle facilitates pressure change. The spring and
adjustment handle are free from contact with liquid elements
being controlled. The maximum temperature for this series is
180°F (82°C). The LFBP30 features Lead Free* construction
to comply with Lead Free* installation requirements.
