An overview of the vacuum valve
vacuum valve is a valve that its working pressure is less than the standard atmospheric pressure, applied to the vacuum system. Vacuum valve is not only with simple structure, small size, light weight, economized material consumption, small installation size, and driving torque is small, operation is simple, rapid, and also has a good flow conditioning functions and closed sealing characteristics, vacuum valves have a wide apllicable field in large and medium diameter, medium and low pressure.
Vacuum valves Category
Common types of vacuum valves are vacuum diaphragm valve, vacuum regulative valve, high vacuum butterfly valve, high vacuum diaphragm valves, solenoid vacuum valve with pneumatic, electro-magnetic high vacuum baffle valve, solenoid high vacuum pneumatic valve, high vacuum fine-tuning valve, high vacuum baffle valve, high vacuum flapper valve, ultra-high vacuum baffle valve, ultra-high vacuum flapper valve,etc.
Vacuum valve drive type
Vacuum valves have manual, pneumatic, electric and electromagnetic four types, namely by manual, compressed air, power supply and the electromagnetic force as a driving force, through the implement actuator to drive the disc (disc, spool) and makes the valve enable opened and closed.
