Belimo B238 Valve

For reliable hydronic system control, consider the Belimo B238 Valve, a robust 1 1/2" NPT 2-way ball valve engineered for precision. This characterized control valve delivers an equal percentage flow characteristic with a 19 Cv, ensuring stable modulation in demanding HVAC applications. Constructed with a nickel-plated forged brass body, a stainless steel ball, and a stainless steel stem, it's built to handle chilled or hot water, including solutions with up to 60% glycol, across a fluid temperature range of 0°F to 250°F (-18°C to 120°C). With a body pressure rating of 400 psi and a close-off pressure of 200 psi, this valve maintains a 0% leakage rate from port A to AB. It's a maintenance-free solution ideal for air handling units, fan coil units, unit ventilators, VAV box reheat coils, and bypass loops, providing consistent performance in variable flow hydronic systems.

• Key Benefits:
