The micro-flow control valve is a small-size, lightweight micro-flow control valve. The major structural unit is comprised of a valve body, pneumatic actuator, and positioner. The valve body is comprised of a body and a bonnet. The port and seat are detachable as a unit from the valve body.
Features:
The minimum rated flow coefficient of Kv can reach 5x10-3, especially for conditions that require precise control of small flow, such as fine chemicals, food additives, medicine, electronics, and other industries.
Benefits:
Micro-flow Control Valve can precisely control the small flow.
