Regulation of flow control/throttling valves
Flow control valves can be used to adjust speed of actuators (if installed on its outlets – e. g. GRLA
type valve type - Fig. 17) or to adjust time delays (when installed on signal cables of control valves
– e. g. GR type valve - Fig. 18). Regulation of valves should always be conducted with air supply
turned on.

Fig. 18. Non-return flow control valve GR type (mounted on cables)
In case of one way flow control valve GRLA type with socket for screwdriver [Fig. 17.a] regulation is
conducted by turning regulation bolt (using flat screwdriver) in appropriate direction. To slow down
actuator movement speed or extend time delay, turn regulation bolt clockwise.
In case of valves with thumb bolt [Fig. 17.b and Fig. 18] regulation is carried out in the same manner
except the necessity to loosen blocking nut before regulation and to tighten it up after adjustment
is finished.
