Main Features
1.Equipped with pneumatic diaphragm actuator.compact size.large output;
2.Use one-piece guided structure ,large guided area;
3. Available to two-way fluid, can bear larger differential drop, large rangeability;
4.High accuracy of flow characteristic;
5. Cage guided structure makes for lower noise and minish the damage to plug caused by flash evaporation and cavitation.
