Check Valves - Henry

Heldon manufacture a time proven range of check valves. Heldon offer a check valve range with optimum flow characteristics and superior checking ability with minimal leak rates. The Heldon range are specially engineered to offer a high Kv value therefore ensuring a low pressure drop.

The brass bodies are forged in the larger sizes with copper extensions on the smaller solder sizes. To optimise the sealing efficiency the 2001 and 2006 series have a soft neoprene seat while the larger valves seat is made from heat-stability Teflon. The larger valves have a reusable neoprene o-ring seal allowing them to be easily dismantled for installation servicing.

Suitable for liquid, Suction and Hot Gas lines with all fluorinated refrigerants these valves are dampened against chatter in low pressure drop situations.

Manufacturing Standards:

• Manufactured in accordance with NA / NZ 1677.2
• Safe Working Pressure: 4,200kPa

Please note that In-line Check Valves are not suitable for discharge lines of reciprocating compressors. This is due to the reciprocating compressors discharge pressure pulsations.

The Henry Technologies range includes both the Lift type and the In-line type Check Valves.

The Lift Check Valves are: 116, 205 & 2027 Series
(Note: 205 Series is replacing the old 2024 Series)

The In-line Check Valves are: 119 & 120 Series
(Note: 119 & 120 Series is replacing the old 2001 & 2006 Series)

Henry Technologies check valve are suitable for HCFC and HFC refrigerants, along with their associated oils.
Typically, Henry Technologies Check Valves will start to open at 3.4 kPa and be fully open at 34 kPa.
