All NW/KF style vacuum connections conform to the international ISO 2861/I standard. KF series quick release flanges also comply with Standard GB4982-85.
Other vacuum components, which may include three-way types, blind plates, metal flexible corrugated pipes, callipers and bolts, heel blocks and holders, comply with the ISO Standard 9000:2000.
They are widely used in the assorted vacuum systems and low-voltage pipe systems, such as electronic, food machinery, the petrochemical industry, and medicine machinery.
Our vacuum fittings come with plastic protective caps which help protect the NW/KF flanges from scratches and dust.
GD-J(b) manual high vacuum damper valve (Angle Valve) is one of the important components in the Vacuum system. The transmission component is in screw structure, depended on the hand power to revolve the wheel and open or close the valve. Applicable medium can be air and noncorrosive gases.
Manual high vacuum valve with KF16 ends at right angles special.
Applicable scope (Pa)
2x105 - 1.3x10-6
Valve leak rate (Pa.L/S)
≤1.3 x 10-7
Applicable temperature (°C)
-25 - 40

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.
