Description
The Parker-Sporlan 101905 is a heavy-duty, two-way normally open actuated ball valve engineered for demanding HVAC and hydronic control applications. Built around a forged brass body with stainless steel trim, this 3-inch valve delivers reliable two-position flow control with a 74 Cv equal percentage flow characteristic — ideal for precise modulation in chilled water, hot water, and condenser water systems.
Powered by a spring-return actuator rated for both 24 VAC and 24 VDC operation, the valve automatically returns to its normally open (fail-safe open) position upon loss of power, protecting system integrity. The ASME Class 150 flanged end connections ensure compatibility with standard piping systems and simplify installation in commercial and industrial settings. Two built-in SPDT auxiliary switches provide end-of-travel position feedback for integration with building automation systems, DDC controllers, and safety interlock circuits.
