ZHM single level sleeve type control va e with high stability, easy maintenance and wide application. It can be designed as balance type for eliminate static unbalance, with damping effect, reduce va e vibration, can be applied in occasion with large pressure difference, can apply with multi-spring pneumatic diaphragm actuator or electric actuator, etc.
Nowadays with the development of the modernized industrial automatic controlling system progressing, the requirement to control va e increased. DATIAN with so many years research and development, developed ZH series direct travel control va e and ZR series angle travel control va e.
Compact structure, advanced operation actuator system. Applicable medium are Liquid, Gas and Steam. DATIAN control va e with high durability and stability, easy for type choosing. Structure simplified, reduced the spare parts in large quantity, more convenien for va e maintenance and reduced the maintenance cost.
