technicians should also inspect the collector box tubing and inducer port for blockages before replacement

When should the KS30331 be used instead of replacing the whole valve

Spartan Valves ME-4840B Actuator 323055-751 though it can be adaptedThe Spartan Valves ME 4840B Actuator is a critical component for technicians managing terminal unit and zone valve applications. This 24Vac spring return proportional actuator is engineered for precise modulation, utilizing a microprocessor based control system to drive 2, 3, or 4 port valves. Operating on a 0 10Vdc control signal, the unit features an internal AC hysteresis brushless motor that provides reliable 28lbs (120N) of output force. The
