GDQ-J(b)-A high vacuum damper valve(Angle Valve)
GDQ-J(b)-A pneumatic high vacuum damper valve(Angle Valve) is sealed by sylpho. Motivated by compressed air, it pushes the cylinder to up and down move with the valve rod by changing the direction of electromagnetism to transform the gas circuit direction, which drives the valve to open or close, in order to cut off or connect gas flow in the Vacuum system. Such valve is advantageous in operating steady and reliable with long life span, which can be the top choice within the automatic vacuum facilities. Applicable medium can be air and noncorrosive gases.
