ZJHS Pneumatic Diaphragm Low-Temperature Angle Control Valve

 

ZJHS pneumatic diaphragm low-temperature angle control valves are mainly used in industrial sectors such as air separation equipment and oxygen generators. They work with regulators and other instruments to control low-temperature gas and liquid media, and are suitable for occasions with strict sealing requirements.
