Siemens Building Technology Mixing Valve Brass FxF Cv HVAC Control Valves & Actuators

Siemens Building Technology brass 3-way mixing valves (also called three-way globe valves or HVAC mixing valve bodies) give precise control of hot water, chilled water, and glycol solutions in hydronic heating and cooling systems. They have female x female (FxF) NPT end connections and brass trim. The line is part of the Siemens Powermite and Flowrite 599 Series. Each valve is rated by its flow coefficient (Cv).

Key Features:

• Three-way globe body for mixing applications, and also usable for throttling or bypass duty
• Female NPT end connections for threaded piping installation
• Brass trim in a durable brass valve body
• ANSI Class 250 construction
• ANSI Leakage Class IV (0.01% of Cv)
• Direct-coupled universal bonnet for simple actuator mounting
• Equal percentage flow characteristic on the normally closed port and linear flow on the normally open port
• Works with compatible Siemens pneumatic or electronic actuators, which are matched to the valve series

Typical Applications: These valves suit hot and chilled water control and water-glycol solutions up to 50%. Common uses include fan coil units, convectors, radiation, reheat coils, unit conditioners, and other terminal units. Choose a Cv rating that matches the flow your system needs. Siemens has a long record in building automation and HVAC controls. Its valves are made for dependable modulating control in commercial and institutional buildings.
