The main parts of these valves are made with the following materials :

• Hot forged brass as per BS-218
• Steel with proper surface protection, for the spindle
• Neoprene rubber for the gland
• Engineering Plastics for the cap that covers the spindle

The three piece design makes the Series C-44 valve the most easily maintainable valve in its type. By removing three body connector bolts and loosening the fourth, the body can be swung away using the fourth bolt as a fulcrum, to carry, out any maintenance on the valve. This feature allows the valve to be online and considerably reduces down time.

The valves can be installed in any section of a refrigerating system, where it is necessary to avoid an inversion of the refrigerating flow. Before connecting the valve to the pipe it is important to make sure that the refrigerating system is clean. Infact the valves with PTFE seats are particularly sensitive to dirt and debris. Furthermore check that the flow direction in the pipe corresponds to the arrow stamped on the body of the valve.

The main parts of the valves are made with the following materials :

• Extruded brass as per BS-218.
• Stainless steel for the spring.
• Neoprene rubber for the gland.
• PTFE for seat.

The brazing of these valves with solder connections should be carried with care using a low melting point filler material. It is necessary to remove the bonnet assembly with spindle and cap prior to brazing the valve. Re-assemble the valve only once the valves has cooled completely and reached room temperature.

The brazing of these valves with solder connections should be carried with care using a low melting point filler material.

• Investment Cast Body – CF.8/S.S.304
• Spindle – Steel
• Seat – Steel
• Gland packing – 99% Graphite
• Springl – S.S.

Diaphragm valves don’t have gland seals. The external sealing is assured by thin metal discs (diaphragms), which hermetically divide the spindle chamber from the fluid flow area.

The main parts of the valves are made with the following materials

• Hot forged brass body as per BS-218
• Extruded brass for the spindle
• Special spring steel for the spring
• Engineering Plastics for seat sealing gaskets

• Can be used on all CFC’s and HCFC’s
• Seat of Engineering Plastics to give complete shut off with minimum torque
• Fitted with stainless steel diaphragms that prevent leakage
• Throughout the operating life of the valve
