Stop needle valves
Applicable to all common refrigerants including R 717 and R744 (CO2) and non corrosive gases/liquids.
No special flow direction is required. The valve is designed to withstand high internal pressures. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion. For further information refer to installation instruction for CSNV-ST
Housing and bonnet material is low temperature steel according to requirements of the Pressure Equipment Directive and other international classification authorities.
Valve safety is enhanced with the spindle being secured such that it cannot be unscrewed.
Suitable for “heavy duty” industrial applications having a very sturdy and safe design including high pressures and wide temperature range.
Compact and light valve for easy handling and installation.
No special flow direction required.
Provide high flow characteristics. Each valve type is clearly marked with type and size.
Temperature range: –60°C to +150°C
Max. operating pressure: 52 bar g ( 754 psig)
