"VOF" Screw to Connect Under Pressure Coupling Series
Connection under residual pressure is allowed in one side
Inspection hole to control if the coupling is completely connected
Wrench flat on the bodies to facilitate the fitting assembly
The poppet valve with elastomer seal provides maximum sealing of the couplings when disconnected
Retainer in high resistance carbon steel
Shape of internal parts is designed to reduce turbulence and pressure drop
High resistance to pressure impulses
Compact design, Simple to use
Before coupling: clean the mating surface of the couplings to avoid dirt inclusion in the circuit
To connect insert the nipple in the coupler, screw the sleeve until positive stop (surface contact of two moving parts), do not push together the couplings, screw only
The use of tools for the second part of the connection can be necessary if there is high residual pressure in the circuit
Check inspection holes to ensure that the coupling is fully connected (no free space allowed)
To disconnect unscrew totally the sleeve from the nipple
