Belimo B239 Valve

For your next hydronic system installation, consider the Belimo B239 2-way ball valve, engineered for precise flow control in demanding HVAC applications. This 1 1/2-inch NPT valve features an equal percentage flow characteristic, crucial for maintaining stable temperature regulation in heating and cooling coils. Constructed with a durable nickel-plated forged brass body and a stainless steel ball and stem, the B239 is built to handle chilled or hot water, including solutions with up to 60% glycol, across a temperature range of 0° to 250°F (-18° to 120°C). With a robust 400 psi body pressure rating and a 200 psi close-off pressure, this characterized control valve delivers reliable performance. Its 29 Cv rating ensures optimal flow capacity for air handling units, fan coil units, and variable air volume (VAV) box re-heat coils, making it a versatile component for efficient building automation systems.
