- VBN/VBF Control ball valves control hot and chilled water in HVAC systems to provide two-position, floating, or modulating functions.
- Order them with or without factory-mounted non-spring return or spring return direct-coupled actuators.
- Flanged control ball valve offering available (VBF)
- Accurate flow control
- Simplified actuator selection with a large range of Cvs
- Built for safety and endurance with a blowout-proof stem to withstand high pressure and optional NEMA 3R enclosure for weatherproofing
- Field replaceable stem allows valve to be serviced and replaced on the pipe
- Threaded 2-Way models up to 3" and 3-Way models up to 2-1/2"
- Parabolic flow insert constructed into the ball provides high quality seals and precise control
- Multi-actuator mounting bracket allows the same bracket to be utilized on all valves
- Removable manual operating handle to control valve during installation or in an event of power failure
With line sizes ranging from ½” to 2” sizes (Cv ranging from 0.4 to 250), Siemens 599 Series Ball Valves can control hot or chilled water and up to 50% glycol solution in convectors, fan coil units, unit conditioners, radiation, and reheat coils.
| FEATURE | FUNCTION | BENEFIT |
| Universal mounting plate | Accommodates different actuator sizes | Allows use of any sized OpenAir actuator on same valve body with no additional linkage |
| Flow optimizer | Generates equal percentage flow characteristic for proper water coil application | Provides linear heating response from control coil – aids in proper loop control |
| Actuator mounting standoff and thermally isolated bracket | Provides a thermal barrier between actuator and valve | Allows actuator to be used in higher temperature applications |
| Manual override handle | Enables hand operation of valve | Allows operator to manually operate valve in event of a power failure |
| Higher close-off | 200 psi close-off for all line sizes | Less worry about close-off pressures; matches or exceeds competitors’ close-off pressure |
| Expanded Cv offering | Provides more options for perfect matching of valve with control loop | Better sizing of valves to the job requirements |
| Full port models available at each line size | Perfect for on/off applications | Allows use of a consistent product line through all applications |
| Stainless steel or chrome plated ball | Provides performance and cost choices | Able to meet stainless steel specifications where required, while offering cost effective chrome plated option across entire product line |
| GQD spring return actuators for ½ and ¾ inch valves | Lower torque, lower priced actuator for small valves | Competitive performance and pricing |
| Utilizes OpenAir Series of direct-coupled actuators | Provides quarter-turn (90°) rotation of valve stem and ball | Proven actuation for precision control of ball valves |
| Double O-ring blow-out proof stem seal | Provides redundant leakage protection and positively protects against blow-out | Ensures long life and consistent performance in the most demanding environments |
| Actuator may be indexed into four positions | Actuator may be mounted to valve in 90° increments | Provides flexibility in installation to adapt to space constraints |
