Description
The Bray Commercial ST05-2-004 is a 1/2-inch, 2-way soft-seated ball valve engineered for precise flow control in commercial HVAC hydronic systems. With a flow coefficient (Cv) of 0.4, this compact valve excels in low-flow terminal unit applications — including fan coil units and zone control circuits — where accurate modulation and reliable, bubble-tight shutoff are critical to system performance.
The Soft Touch design delivers low-torque operation that reduces actuator wear and extends valve seat service life, making it an ideal long-term solution for demanding commercial installations. Its compact form factor fits easily into tight mechanical spaces, and full compatibility with a wide range of Bray Commercial actuators makes automated control integration straightforward.
