SIEMENS VBF21.65 Three-Way Rotary Valve DN65 PN6

SIEMENS VBF21.65 THREE-WAY ROTARY VALVE DN65 PN6

Backed by ORFA Industrial – Precise Flow Control in HVAC Systems

Considered the heartbeat of heating, ventilation, and air conditioning (HVAC) systems, the three-way rotary valve automatically balances cold and hot water flows according to temperature changes, maximizing building comfort. The Siemens VBF21.65 model, as a professional three-way rotary valve body, with DN65 diameter, flanged connection and PN6 pressure rating, meets the requirements of medium and large-scale installations. Made of cast iron, this three-way rotary valve body provides stability within a temperature range of 1°C to 120°C and offers a service life of 25 years. Thanks to its high Kvs value of 63 m³/h, the three-way rotary valve maintains hydraulic balance and flow control even in large liquid volume industrial applications. Indispensable in industrial cooling towers, heat recovery systems, and mixing heating applications, this three-way rotary valve is designed for compatibility with Siemens SAX, SKD, and SKB series actuators. With a corrosion-resistant internal channel design, the three-way rotary valve maintains static tightness without requiring prolonged maintenance for many years. Available from ORFA Industrial stock, this three-way rotary valve is the standard choice for outdoor temperature compensated and mixing type heating systems. Each three-way rotary valve unit undergoes quality control testing, is ISO certified, and ensures full safety at a working pressure of 6 bar (PN6). Efficient use of a three-way rotary valve in your installation reduces energy consumption by up to 15%, directly lowering operating costs. Thanks to its flanged mounting system, the three-way rotary valve can be easily installed without special tools, and maintenance can be performed effortlessly. With a three-way rotary valve manufactured to Siemens quality standards, achieve smooth control in flow diversion or mixing applications.

Achieve perfect flow balance and energy efficiency in your HVAC systems with the SIEMENS three-way rotary valve body.
