Kuwait Normally closed pneumatic high vacuum baffle valve

GDQ-J-A series normally closed pneumatic high vacuum flapper valve relies on compressed air as the opening and closing power of the valve plate through the electromagnetic reversing valve. When the power supply or compressed air is lost, the valve with a diameter below DN80 will automatically close by spring force. Valves, the valves above DN100 use the one-way valve to quickly close the original air source pressure of the cylinder through the solenoid valve group to automatically close the valve. So as to achieve the function of quickly cutting off the air flow in the vacuum system. The shaft seal structure of pneumatic high vacuum baffle valve can be divided into GDQ-J-A type rubber seal and GDQ-J-A(b) type bellows seal. GDQ-J type is the angle through type, and GDQ-S type is the three-way type with pre-extraction. The applicable working medium is air and non-corrosive gas.
