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. |
