ZXP/ZDLP/ZAZP series pneumatic/motorized single seat control valve  structure is top guiding.The advantage as below:

1, using the balance plug, allowing large differential pressure, stable operation.

2, valve guide is large, the oscillation caused by the eddy current and impact can be improved,and reduce damage.

3, simple structure, easy assembly and disassembly and maintenance.

4, Sensitive action

5, S type Flow  channel, low pressure drop loss, large circulation capacity,flow characteristic  precise,easy maintenance.

The products are widely used in chemical, petrochemical, chemical,  electric power, metallurgy, environmental protection and other industrial  department of automatic control system
