Spindle seal is made by an o-ring of perbunan. Needle regulating valves seal by means of a stainless steel cone, thus allowing continuous regulation between »on« and »off« (open and closed). Drain Valves Drain valves of brass, straight or elbow-type, originally served to let out the condensation at the lowest point of compression tank. Today they are generally used for air exhaust.
