Vacuum Charge Angle Valves

Brief Introduction:

This series of valves are made up of pneumatic and electromagnetic charge valves. The design of this seriesstructure is reasonable, and the appearance is excellent. Besides, they have many advantages, such as stabilitysmall size, durabilty, great sealing, long service life and so on. Mainly installed at the air inlet of mechanical pump.power and motor of mechanical pump is tied to the same circuit. so the start and stop of the pump are with valvessynchronously. When the pump stops, valves can close vacuum system automatically, keeping the vacuum degreeand also fill air into pump chamber and pump air inlet, and then avoid counter flowing of pump oil and pollutingvacuum system. As a result, they are one of initial optional valves in automatic vacuum equipment. Valves takecompressed air or electromagnetic force as motivity to make valves start and stop. Valve plates will close automaticallydepending on spring force when losing air source. Applicable medium can be pure air and non-corrosive gas.

Features:

□ Design in a standard way and easy to change and maintain.

□ Easv to clean up.

□ Charaing port adopt taper sealing, only litle air is filled into the vacuum chamber when stop the valves

□ Electromagnetic valves are designed in an energy saving way and the size is small.
