REFRIGERANT GASES
Filling Head
for Handwheel Valves
Semi-automatic Operated
MATERIALS AND STANDARDS
The Filling Head is made of corrosion-resistant materials such as stainless steel, brass, aluminium and special polymers. The rubber materials
used are developed and manufactured according to the requirements of EN 549.
FEATURES
1. Insignificant loss of product when the gas flow is cut off and the filling head is released from the cylinder valve.
2. Includes anti-filling device opener.
3. Balanced jig for easy suspension between filling operations.
4. Easy to manually connect and disconnect. Filling is initiated simultaneously with the connection to the valve.
5. Slim design makes it easy to handle and it fits easily inside any shroud.

Inlet connection: Freon: 1/4” NPT
Pneumatic air: 3/8” NPT.
Outlet connection: Connects to standard outlet male threads such as G1, G2, G4, G5, G6, G8, G11, G12 acc. to EN 12864. Valves with
and without SRV.
Supply pressures: The Filling Head is designed to operate within the normal supply pressures.
Pneumatic supply: 6-10 bar. Liquid filling product: 1-20 bar
Filling time approx. 2 sec./Kg liquid at 7 bar differential pressure.
Marking: The following information is marked on the Filling Head:

Packing: The Filling Heads are individually packed in cardboard boxes without instructions.
Function and The Filling Head is easy to operate. The clamping brace is placed around the neck of the cylinder valve.
Maintenance: Once the Filling Head outlet is aligned with the Cylinder valve inlet, the ball knob is pushed to allow the
compressed air to fill the pneumatic cylinder. This forces the Filling head outlet to attach the cylinder valve outlet
thereby obtaining a leaktight connection and simultaneously opening the gas seal initiating the FREON flow.
After completing the filling operation the handle on the side of the pneumatic cylinder is pushed and the air
pressure is released thereby stopping the flow of gas and the outlet disconnects from the cylinder valve. All rubber
seals inside the gas section as well as the complete pneumatic cylinder can be exchanged.
