Description
Parker-Sporlan 101910 — 2-Way Normally Open Actuated Ball Valve Assembly
The Parker-Sporlan 101910 is a heavy-duty, 2-way normally open actuated ball valve assembly engineered for precise flow control in commercial and industrial HVAC and hydronic systems. Featuring a 3-inch connection with an ASME Class 150 flange, this valve delivers a high flow capacity of 211 Cv with an equal percentage flow characteristic — ideal for modulating applications that demand accurate, repeatable control across a wide range of operating conditions.
The forged brass body provides exceptional strength and corrosion resistance, while the stainless steel trim ensures long-term durability and reliability in demanding environments. The spring-return actuator guarantees a safe, normally open fail position in the event of power loss, protecting system integrity.
