This small safety device that can arrest the air flow in lines or systems (such as scuba filling whips) if that apparatus should fail (hose rupture, O-ring failure, etc.) The flow is reduced to approximately 10%, so personnel can shut down the system with minimal risk and air loss. Flow restriction is adjustable but comes factory preset to approx. 80 SCFM at 5,000 psi and 55 SCFM at 2,500 psi. 1/4 NPT female inlet with 1/4 NPT male outlet. 6,000 psi working pressure.

Repair kit for #46320 relief valve. Includes poppet and seat.

Prudent dive shops strive to maintain a low dew point in their scuba air and also achieve maximum life expectancy from expensive filter cartridges. However, air must be 99% dry before entering the chemical filters or neither objective will be met! To accomplish this, an after-separator and a priority valve are required. The latter unit is an adjustable check valve which holds about 1700 psi of back-pressure on the filter system at all times. This raises the density of the air, increases the...

Adjustable "pop-off" valve which can be calibrated from 300 to 5,500 psi. Anodized aluminum for 6,000 psi service. 1/4" NPTM inlet. Used to protect filters, separators, storage vessels or compressor interstages. Comes uncalibrated with instructions. Additional Info: These special valves are used to protect pressure-sensitive components or to relieve pressure at some prescribed level in compressed air systems. Standard relief valves are designed for sudden, intermittent, and sporadic service,...
