GDQ-JA series normally closed pneumatic high vacuum baffle valve is turned by a solenoid valve to rely on air power as the opening and closing valve plate in the loss of power or compressed air when the valve diameter DN80 following spring force will rely on self-closing valve door, DN100 and above using one-way valve through the solenoid valve cylinder valve quickly closed the original gas supply pressure to automatically close the valve. Vacuum system to achieve the cut off the flow of the function.
GDQ-J model for the angle-pass type, GDQ-S model for the mouth of the links with pre-pumping type. Applicable to the work of the media to air and non-corrosive gases.
