Industrial Applications
- The throttle/check valves type DRV serve to set an exact oil flow in one direction, and to allow free return flow in the opposite direction.
- Throttle/check valve DRV consist basically of a housing (1), adjustment knob (2) with locking device (3). By turning the adjustment knob (2) to the left, the spindle (4) with throttle pin (5) increases the flow section (6) to maximum. By turning the adjustment knob (2) to the right, the spindle (4)with throttle pin (5) decreases the flow section (6) until fully closed without leakage. For repeat setting, a colour scale (7) is provided on the top end of the spindle (4).The area of coloured triangle (8) showing indicates how far the valve is open (the larger the coloured triangle the greater the opening). The flow setting is locked by means of locking device (3).
