Micro electric regulating valveIt is usually composed of micro electric actuators and regulating valves (such as needle valves, single seat valves, etc.). By receiving signals from industrial automation control systems (such as 4-20mA current signals), the valve is driven to change the cross-sectional area between the valve core and seat, thereby accurately controlling process parameters such as flow rate, temperature, and pressure of the pipeline medium.
Micro electric regulating valveThe technical parameters vary depending on the model and specifications, but typically include the following key parameters:
Nominal diameter: Refers to the nominal diameter of a valve, with common specifications including 3/8 inch, 1/2 inch, 3/4 inch, 1 inch, etc.
Seat diameter: affects the flow capacity and flow characteristics of the valve.
Rated flow coefficient: Refers to the flow capacity of a valve under specific conditions, usually measured in KV (flow coefficient).
Allowable pressure difference: Refers to the maximum pressure difference that the valve can withstand under normal operating conditions.
Nominal pressure: Refers to the nominal pressure rating of the valve, with common specifications including 1.6MPa, 2.5MPa, 4.0MPa, etc.
Rated stroke: Refers to the distance that the valve moves from fully closed to fully open.
Valve cover form: Depending on the working temperature, it can be divided into standard type, high temperature type, low temperature type, etc.
Cover form: usually adopts bolt compression type to ensure the sealing of the valve.
Sealing packing: V-shaped polytetrafluoroethylene packing or V-shaped flexible graphite packing is used, which has good sealing performance and corrosion resistance.
Valve core form: Needle type valve core is suitable for small flow regulation and has the characteristics of high flow capacity and low flow resistance loss.
Flow characteristics: usually linear, representing the relationship between valve opening and flow rate.
Configure actuator categories: such as PSL series, 3810L series, and other electric actuators, which can be branded according to customer needs.
Executive parameters: including power supply voltage, input signal, output signal, protection level, explosion-proof sign, etc.
