Cast iron electric regulating ball valve
application:
SRB series electric regulating ball valves are widely used in fluid control of central air conditioning, heating, water treatment, industrial processing industry and other systems. The matched actuator is SACRB series. The actuator receives the standard adjustment model or tri-state floating point signal, and rotates the ball to the specified position.
Features:
-Unique conical inlet design to achieve precise equal percentage flow control characteristics
-Simple flow channel design, not easy to block, more safe and reliable to use
-High circulation capacity, low resistance loss
-Double seal design, no leakage and double insurance
-Ultra-quiet flow channel design to ensure a quiet environment
-High shut-off pressure, high pressure rating
-Equipped with manual switch and opening indication
working principle:
SRB series electric regulating ball valve is driven by angular stroke actuator SACRB. The actuator drives the valve to change between the ball and the seat by receiving the regulating signal (0-10V or 4-20mA) or tri-state floating point signal of BA system. To control the flow through the valve and realize the automatic adjustment function.
