Advantages
Why Choose Hearken Pneumatic Diaphragm Valves?
No Retention, Full Exhaust
Hearken pneumatic diaphragm valve uses a weir-type flow channel. The optimized channel design can form no medium retention area in the valve body channel, ensuring that there is no liquid accumulation in the internal channel after the pneumatic diaphragm valve is closed. At the same time, the fully enclosed diaphragm used in the pneumatic diaphragm valve can completely isolate the valve body cavity from the pneumatic actuator, and the medium will not come into direct contact with metal or mechanical parts, effectively reducing the risk of contamination.

Wide Temperature Adaptability
Hearken pneumatic diaphragm valve has a wide temperature range of -20℃+150℃. The tested valve body material is not easy to age or corrode after long-term operation, which will cause performance degradation, ensuring stable operation in outdoor environments with large temperature differences between day and night.
