Characterized control valves with actuators
Characterized control valves with actuators
Characterized ball valves have a v-notch in the ball or a v-notched disc which provides better flow control over a regular ball valve design. A characterized ball valve is used to control and modulate flow. It gives more stability compared with other kinds of valves. They can withstand higher pressure, are lighter and cheaper. We are offering different actuators for these valves. The valve with the actuator can function as an opening, closing and mixing valve for domestic hot water or heating and cooling the building. It can also be used as a room temperature controller. Water valves and actuators are used for automatic temperature maintenance and water flow regulation.
2 way and 3 way characterized ball valves
2-way and 3-way characterized disc ball valves NVCB are mainly used in the HVAC system to regulate the flow of water and steam in response to the demand of a controller. High close-off pressure actuator satisfies the demanding requirements of high-rise buildings and high-pressure pumping systems. These valves are recommended to control with Nenutec NABA or NABM actuators, or if you need an electronic spring return function with NEBA or NEBM actuators.

Ball valve spring return actuator
Ball valve spring return actuators NEBA and NEBM are specially designed and produced for general characterized ball valve control when a fail-safe function requires. During normal operation, the actuator motorizes the damper. When the power supply is off, the actuator springs back to its original position. Our wide range of spring return ball valve actuators has been developed to operate and position ball valves of different sizes.
Features
- Torque 5 – 10 Nm
- Power supply 230 VAC or 24 VAC / VDC
- Running time 50 – 70 sec
- Auxiliary switches optional, 1 x SPDT (adjustable)
