Vacuum actuators Vacuum actuators: optimal control of the valve position.These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. Also the adjustment of the throat section at the inlet to modify and optimize the air flow and air velocity inside a Turbo charger is controlled by… Read More »Vacuum Actuators

Vacuum Adapters Vacuum adapters are portable connectors to connect evacuated tube quickly, using for connecting some vacuum fittings such as KF flanges and fittings, CF flanges and fittings and ISO flanges and fittings, to guarantee vacuum welding and material to reach the standard. Especially material is more strict with connecting to soft… Read More »Vacuum Adapters

Center Ring Center ring belongs to a connecting part for a vacuum pipe fittings such as a pipe, a pump and a valve. When vacuum system applied, due to the difference of conditions, there is no uniform standard, so we must regulate what is the standard. The combination of the center ring… Read More »Center Ring

CF Flanges and Fittings

Kaysuns manufactures and provides a complete line of CF fittings and flanges. A different vacuum fittings type from KF fittings and flanges , ISO fittings and flanges. CF fittings are ideal for ultra-high vacuum environments and are ready to use as received. CF Components, CF Fittings and CF flanges are available in a variety of configurations.
