상품 소개

The Venturi airflow control valve uses a shaped throat and movable cone to create a repeatable relationship between cone position and airflow. A mechanical spring shifts the cone in response to duct-pressure change, while the actuator establishes the opening required by the control command. Because pressure compensation occurs inside the valve body, the controller can respond without continuously deriving airflow from a separate duct sensor. Stainless wetted components and an external actuator make the assembly suitable for supply, general exhaust and laboratory exhaust duties.

주요 기능

A calibrated Venturi throat and cone produce a stable position-to-airflow characteristic over the operating range.

Mechanical spring compensation reacts directly to static-pressure variation before the room-pressure loop drifts.

A fast external actuator supports fume-hood tracking and rapid room supply-to-exhaust balance changes.

Smooth stainless internal surfaces and external drive components reduce residue traps in demanding exhaust service.

고객 제품 관심사

Critical-room airflow control must remain repeatable through duct-pressure swings, react quickly to demand and tolerate contaminants without a drifting measurement element.

A fan-speed change alters several branch flows before the room pressure loop can recover.The spring-loaded cone compensates mechanically for the duct-pressure change at each valve.

Fume-hood sash movement requires a large exhaust change within seconds.A characterized cone and fast actuator move directly to the airflow position commanded by the hood controller.

Dust or chemical residue blocks small pressure-sensor ports in an exhaust branch.The pressure-independent cone mechanism controls flow without small in-stream averaging taps.

Mismatched supply and exhaust response reverses the intended room pressure direction.Coordinated valve commands and known flow-position curves maintain the scheduled offset between room air paths.
