Description
The Reznor 101902 is a heavy-duty, two-way normally open actuated ball valve assembly engineered for demanding commercial and industrial HVAC and hydronic applications. Built around a forged brass body with stainless steel trim, this valve delivers reliable equal-percentage flow control with a 74 Cv flow coefficient through a full 3-inch port. The spring-return actuator ensures fail-safe normally open operation on a loss of power, while the 120VAC two-position electric actuator provides precise on/off control. Dual 2-SPDT auxiliary switches provide end-of-travel feedback for integration with building automation or control panels.
