♦ Application
Series SRB electric control ball valve is widely used to
regulate the flow in center air-conditioning, heating, water
treatment and industry processing systems. It is driven by
the Series SACRB rotary actuator. After receiving a standard
regulation signal or a floating point signal, the actuator rotates
the ball in the valve body to the designated opening position.
♦ Features
- Accurate equal percentage flow control characteristic
achieved by its unique coned water inlet
- Concise structure of flow passage largely avoids blockage
- High flow capacity and low resistance loss
- No leakage by using double shaft seal
- Super silence design achieves quiet operation
- High shutoff pressure and high working pressure
- Equipped with manual lever and opening degree indicator
♦ Operating Principles
Series SRB electric control ball valve is driven by the
Series SACRB rotary actuator. After receiving a standard
regulation signal (0-10V or 4-20mA) or a floating point signal,
the actuator rotates the ball in the valve body to the designated
opening position. Because the flow area between the valve ball
and the valve seat is increased / decreased by this rotation,
the flow through the valve is regulated correspondingly. This is
the valve’s auto-control process.
