Description
The Belimo B215HT186 is a precision-engineered 2-way ball valve purpose-built for demanding hydronic and steam applications. Featuring a robust brass body paired with a stainless steel ball and stem, this valve is designed to withstand the rigors of high-temperature water service up to 266°F and low-pressure steam systems, making it an ideal choice for commercial and industrial HVAC installations.
With a 1/2″ NPT connection and a flow coefficient (Cv) of 1.86, the B215HT186 delivers accurate, repeatable flow control through its equal percentage flow characteristic — ensuring precise modulation across the full range of valve travel. The valve is also rated for use with glycol solutions up to 60%, providing added versatility for freeze-protection applications in hydronic systems.
Designed to pair seamlessly with Belimo actuators, this valve body is a trusted component in building automation and hydronic control systems where reliability and long service life are non-negotiable.
