Belimo B225HT1856 Valve
The Belimo B225HT1856 is a high-performance 1-inch NPT 2-way control valve engineered for demanding hydronic and steam applications. Featuring a 18.56 Cv rating and an equal percentage flow characteristic, this valve ensures precise modulation in heat exchangers and AHU coils. The construction utilizes a forged brass body with a 304 stainless steel ball and stem, specifically designed to withstand high temperature water up to 266°F and low pressure steam up to 15 psi. This model excels in systems with up to 60% glycol concentration, providing reliable shut-off and chemical resistance. Contractors typically pair this valve with non-spring return actuators or electronic fail-safe models for integrated building automation. Designed for HVAC zone control and commercial boiler loops, the B225HT1856 minimizes hunting and maintains stable loop pressure, reducing wear on downstream components while optimizing thermal transfer efficiency.
Key Benefits- Corrosion Resistance: The stainless steel ball and stem prevent pitting and scaling in harsh fluid environments.
- Thermal Versatility: Rated for low pressure steam applications and high-temp hydronics, providing a single-source solution for mixed-use plants.
- Leak Prevention: Features a blowout-proof stem design and PTFE seats for high-cycle reliability.
- Linear Control Logic: The specialized disc design creates an equal percentage flow, ideal for maintaining temperature setpoints.
What is the maximum differential pressure for the B225HT1856?
This valve is typically rated for a close-off pressure of 100 psi, though the specific differential for modulation depends on the torque of the attached Belimo actuator.
Can this valve be field-repaired?
While the valve body is robust, these units use a factory-sealed design to ensure zero-leakage performance; field replacement of the assembly is recommended over component repair.
Is the B225HT1856 compatible with my existing Belimo linkage?
This 1-inch ball valve is compatible with various LR, AR, and AK series actuators using the appropriate HVAC valve linkage kits.
