Adjustable differential pressure control valve is a flow control device used in heating and air conditioning duct systems. It can manually or automatically adjust the opening of the valve according to needs to control the flow and maintain a set differential pressure.
Main Features of Adjustable Differential Pressure Control Valve
Flow Adjustment: The adjustable differential pressure control valve can manually or automatically adjust the valve opening according to requirements to control the flow in the duct system.
Differential Pressure Control: This type of valve can maintain a set differential pressure by adjusting the valve opening, ensuring the pressure within the duct system is within a reasonable range.
Precision: The adjustable differential pressure control valve has a relatively high degree of control precision, capable of meeting the requirements for applications with higher demands for flow and differential pressure control precision.
Multiple Control Methods: The adjustable differential pressure control valve can be adjusted manually via a handwheel, or controlled automatically by an electric actuator or other means to achieve flexible and diverse flow and differential pressure adjustments.
