Throttle Valve Sandwich Construction type ng6 with interface acc. To iso 4401-03. The throttle valve is available in two different variants, namely the standard and the precision throttle (fd). Version fd only available for sandwiches with restriction in a, b, or ab. The turning knob is made from aluminium, all other parts made of steel, have been phosphated.
Using the precision thread adjusting spindle, the restriction of the volume flow can be continuously adjusted. With the spindle fully screwed home, the volume flow is zero, and a metallic edge makes a leak-tight closure. The throttle effect is produced by an annular gap which can be varied in size, or by means of a triangular edge. Because of the nature of the design, there is only a small amount of leakage. applications and wich type throttle valves can be used anywhere where volume flows have to be infinitely controlled in both directions without taking pressure fluctuations into account. These sandwich valves are ideal for machine tools and also all types of handling operation.
The throttle spindle in case of ADRP, ADRT and adept is not secured against being unscrewed.
