Description
The VB210R-20BS09 ball valve is a compact two-way regulating valve designed for hot and chilled water systems. With a DN20 (3/4”) Rp internal threaded connection and a kvs flow coefficient of 6.3 m³/h, it provides accurate and stable flow control with equal percentage characteristics.
Its forged brass body ensures durability and strength, while the stainless steel ball, stem, and trim deliver excellent resistance to wear and corrosion. The valve is engineered for high system pressures, with a PN40 class rating and maximum static pressure of 40 bar, making it suitable for demanding HVAC and building automation environments.
The VB210R-20BS09 is designed with a low-friction sealing system for smooth operation, ensuring compatibility with compact actuators. It supports proportional or on/off control with tight shut-off performance and minimal leakage (≤0.01% of Kvs), meeting Class IV standards. Its wide operating temperature range makes it adaptable for a variety of heating and cooling systems.
