Description
The Parker-Sporlan 475434 is a high-performance Two-Way Pressure Independent Control Valve (PICV) engineered for precise hydronic flow control in commercial HVAC systems. Combining a brass body with stainless steel trim, this valve assembly delivers reliable equal percentage flow characteristics while eliminating the need for separate balancing valves — simplifying system design and commissioning.
The integrated spring-return, two-position SPST direct-coupled actuator operates across a wide voltage range of 120VAC to 250VAC, making it compatible with a broad range of building automation and control systems. The normally open (NO) fail-safe configuration ensures the valve opens upon loss of power, protecting the system under fault conditions.
