3-way zone valve BVQ-3100
0%
Presentation
The BVQ-3100 internally threaded zone ball valves are specially designed for use with Seltron AQD actuators. The valves have a quick and easy mounting connection for actuator.
- For domestic and commercial heating and cooling hydronic closed systems.
- For diverting and change over applications.
Features
- Quick assembly of the actuator.
- DN15 ÷ DN32.
- Blow-out proof stem.
- Low operating torque.
- Mistake-proofing assembly of the actuator.
Outlined functions
Quick assembly of the actuator
The actuator is assembled on the valve by hand, without tool use, by moving the
actuator vertically downwards (snap).
Mistake-proofing assembly of the actuator
Only one position of assembling the actuator to the valve is possible. Slots must match the ribs on the valve neck. To remove the actuator from the valve, the metal pin must be pulled out to the unlocking position.

Flow directions of the BVQ valve
Designed for Seltron AQD actuators
AQD actuators are designed for operating 3-way BVQ3100 zone ball valves.
Actuators controlled by 2-point signal are recommended for diverting applications.
Valves can also be used in combination with other actuators from the AQD family, controlled by 3-point or modulating control signal.
