ZHM single level sleeve type control valve with high stability, easy maintenance and wide application. It can be designed as balance type for eliminate static unbalance, with damping effect, reduce valve 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 valve increased. DATIAN with so many years research and development, developed ZH series direct travel control valve and ZR series angle travel control valve.

Compact structure, advanced operation actuator system. Applicable medium are Liquid, Gas and Steam. DATIAN control valve with high durability and stability, easy for type choosing. Structure simplified, reduced the spare parts in large quantity, more convenien for valve maintenance and reduced the maintenance cost.
