Electric And Pneumatic Operated Straight Travel Three-Way Control Valve
Product introduction:
L202302 straight travel three-way combination / splitting control valve adopts double valvecore and valve seat guide structure. it regulates and controls the concentration and separationof several flow channels. Two channels enter and one channel exit is called three-way merge.One flow channel in, two flow channels out is called diversion. The standard closing /splittingcircuit is designed as an unbalanced two-seat trim structure. At the same time, the form ofbalanced internal parts can be used to effectively reduce the unbalanced force caused bythe medium pressure difference. Change the area of the throttling surface to control theadjustment or cut-off function of the equalized flow composed of the merging or splittingof any flow path. Special valve cage internals such as noise reduction and anti-cavitationcan be used according to the working conditions.

Product features:
1. The fluid of the three-way regulating valve is in a flow open state in the direction of action on the valve core, so it has good working stability.
2. The servo amplifier adopts deep dynamic negative feedback, which can improve the adjustment accuracy.
3. The thermal oil electric three-way regulating valve saves automation investment. Compared with single seat, double seat, or sleeve regulating valves, forming the same system can save one valve, simplify the system, and save investment.
4. Electric operators come in various forms and can be applied to 4-20mA. DC or 0-10mA. DC.
5. The electronic electric regulating valve can be directly controlled by the current signal to control the valve opening. No need for servo amplifier.
