The standard versions are listed in the type survey. When ordering any of the standard versions, please state type numbers as well as catalog number to preclude possible misinterpretations. When inquiring about or ordering units not listed in our type survey of this publication, the type number made up by you by means of the type key, however, will do. The corresponding catalog number will then be stated in our confirmation of order. Example of how to order Wanted: Throttle check valve size 10, threated connection G 3/8, manually actuated.

3 Construction The throttle check valve throttles the flow in one direction A to B while allowing free passage in the other direction via the incorporated check valve (B to A). The throttling is effected by a longitudinal notch worked into the adjusting spindle. The cross-sectional area of the restrictor is in a linear relation to the adjusting path. The last turn of the knob fully opens the passage. Actuation Adjust flow means of the rotary knob. The colored scale makes it easy to repeat the set values. The area of the colored triangle indicates the size of the crosssection of the passage. A set screw prevents inadvertent adjustment. Mounting The check valves are mounted inline or in switchboard.
