Honeywell ML6420A3049 SPDT NSR Valve Actuator 135 LBF 60 Sec

The Honeywell ML6420A3049 NSR Valve Actuator SPDT 135Lbf 60Sec is a pneumatic spring-return actuator used on 2-way valves in multiple HVAC applications. This is a single-acting design with a spring return to a fail-safe position to enhance system safety in the event of power failure. The actuator runs on compressed air and delivers a force of 135 lbf with an operating cycle of 60 seconds. This strong actuator is ideal for the operation of dampers, valves and other pneumatic accessories in HVAC systems such as chillers, boilers, fan coil units and Variable Air Volume boxes. Some of the benefits include; it operates reliably, is easy to install and maintain, and can work with almost any control system.
