Vacuum pneumatic valve six major characteristics

the following vacuum pneumatic valve stop briefly introduced:
a, small pneumatic valve pneumatic high vacuum flapper valve body are precision castings
high-tech precision casting technology and equipment, made of stainless steel casting full dense tissue structure can be obtained. Complete without 'porosity, loose, sand inclusion' and other casting defects. Neat, beautiful shape. Pneumatic valve leak rate is better than that of - Pa. M/S。 Complete suitable for ultra high vacuum conditions.
2, GYC - JQ series electromagnetic high vacuum differential pressure type pneumatic pneumatic valve to avoid return oil performance improved greatly with the
on the structure of the high vacuum differential pressure type pneumatic pneumatic valve stop improvement, make product performance more stable, more appropriate mechanical vacuum pump operating mode request. There are three key can sex has improved: ( ） 。 Close the pneumatic valve time reduced to <. Second, more conducive to avoid return oil; （ ） 。 Pneumatic valve open time is a little delay, as long as the vacuum pneumatic valve talents open after reached a certain value, if no pressure difference when back to normally open state, （ ） 。 Vacuum leak rate of the products as well as get progress, from low vacuum to high vacuum values, complete can satisfy the high vacuum condition request, such as higher request to the peace of the rotary vane pump inlet pneumatic valve.
3, common one-piece high vacuum pneumatic ball valve throttle mouth regulate pumping speed more superior
the one-piece recuperated high vacuum pneumatic ball valve adopts the 'V' type throttle mouth makes regulate pumping speed more superior, the main path of the exhaust tube mounted on single crystal furnace is used to regulate the extraction rate of furnace body, changes the old 'butterfly pneumatic valve + baffle pneumatic valve' combinations.
4, GDC J high vacuum electromagnetic damper pneumatic valve and DDC JQ vacuum pneumatic electromagnetic valve coil electricity for a long time will not produce high temperature
scientific control circuit and electromagnetic road design makes the electromagnetic solenoid coil has been working in high efficient province work condition. At room temperature ℃ under the condition of continuous coil surface temperature ℃ or less work hours, product shell temperature is lower. And electronic components don't hot. This will never burn out the coil phenomenon appear.
5, high vacuum flashboard pneumatic valve driver installation can be placed on the side
usually board the height of the pneumatic valve is high, there are defects of equipment height space is large. In order to restrain the defect we will drive installation design on the side, greatly shorten the height of the pneumatic valve size, reduce the equipment space form in this system.
6, pneumatic high vacuum butterfly valve USES the high platform design
ordinary pneumatic, electric high vacuum butterfly valve USES a bracket/cohesive set of devices, scientific design of the device directly high platform, make the actuator device is simple.
