9D BACKFLOW PREVENTER

A continuous pressure type with intermediate vent. Particularly recommended for boiler feed lines to prevent backflow should supply pressure fall below system pressure. Primary check valve features rubber-to-rubber seating for tight closure.

Leakage is vented to atmosphere should the downstream check fail. Brass body with stainless steel and durable rubber working parts. Female union connections. Maximum pressure, 175 psi; maximum temperature, 225°F

Provides On-Off or diverted control of hot or cold water, used primarily in zoned hydronic heating systems.

Consists of a valve assembly and long-life synchronous actuator motor which can be removed or replaced without draining the sys- tem. Manual opening lever for valve operation on power failure; valve returns to automatic position upon restoration of power.

V4043 - Straight-thru valve body configuration, normally closed when de-energized. Controlled by SPST line voltage power source.

V8043 - Straight-thru valve body configuration, normally closed when de-energized. Controlled by SPST 2-wire, 24 volt control includes end switch.

V8044 - 2-position 3-way diverting valve body configuration, port “A” normally closed when de-energized. Controlled by SPST 2-wire, 24 volt control.
