Valves work smoothly, never stick. Highly responsive vacuum provides strong suction power in the vacuum pads and enables the use of small vacuum pumps. Can work with a common filter even in very dusty environments. Excellent for use with devices which should not come in contact with oil. Compact design enables easy installation to a control panel.
