Siemens 3 Way NPT Globe Valve
The Flowrite VF 599 Series ANSI Class 250 3 way valves are designed to work with either a pneumatic or electronic actuator with a 3/4-inch (20 mm) stroke.
A typical application for the Flowrite 3 way valve is the mixing of two different temperatures of water supplies.
The valve can also be used for throttling or bypass coil control applications. A pump is recommended on the coil circuit to improve the heat transfer characteristics of the coil and for freeze protection.
Belimo Damper Actuators
Belimo damper actuators are easily mounted with VSI damper linkages.
These actuators are available in 24VAC, 120V or 220V, modulating or floating service as well as spring return or non-spring return.
Belimo offers a fail-safe version of larger damper actuators. Fail-safe actuators are a cost-effective alternative to mechanical spring return.
Please contact a VSI representative for additional options.
