Description
The Mars 62461 is a two-way, normally closed zone valve assembly engineered for precise hydronic zone control in residential and light commercial heating and cooling systems. Featuring a spring-return, two-position actuator design, this valve automatically returns to its closed (fail-safe) position whenever power is removed — ensuring system protection and energy efficiency without manual intervention.
With a 1/2″ NPT connection and a 1.0 Cv flow coefficient, the Mars 62461 is ideally sized for standard zone circuits, delivering consistent and reliable flow regulation. The 120VAC operating voltage makes it compatible with the vast majority of residential and commercial hydronic control systems and zone panels.
