2nd stage shut off / free flow control device 9/16"
Can be installed on any 2nd stage (which uses the standard 9/16 connection) and allows an immediate stop of the air flow
Enables complete protection against second stage leakage during the dive
Also ideal for stage controllers where it is necessary to avoid gas loss
Connection designation and dimension according to standard:
side to the regulator hose 9/16" 18 UNF MALE, approx. 14.288 mm / side to the 2nd stage 9/16" 18 UNF FEMALE, approx. 14.288 mm
Note when using a shut off / free flow control device:
The use of a pressure relief valve / OP valve on the 1st stage of the regulator is mandatory and protects the regulator. The overpressure valve is mounted in the 3/8" medium pressure outlet and opens when the pressure in the regulator exceeds a defined value.
We gladly recommend our compact overpressure valve at a reasonable price.
