The valves are available in two different versions - REG-SA and REG-SB designed for regulation purposes in liquid and expansion lines.

The valves are designed to meet the strict quality requirements on refrigerating installations specified by the international classification societies and are carefully designed to present favourable flow conditions and accurate linear characteristics.

REG-SA and REG-SB are equipped with vented cap and internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure.

Applicable to HCFC, HFC, R717 (Ammonia) and R744 (CO2). Can be used in chemical and petro-chemical applications.

Modular Concept: -Each valve housing is available with several different connection types and sizes. -Possible to convert REG-SA or REG-SB to any other product in the FlexlineTM SVL family (stop valve, stop check valve, check valve or strainer) just by replacing the complete top part.

Fast and easy valve overhaul service. It is easy to replace the top part and no welding is needed.

Designed to ensure perfect regulation

Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure.

Easy to disassemble for inspection and possible repair.

Long neck versions (DN 15 to DN 40) for insulated systems available from parts programme.

Max. operating pressure: 52 bar g (754 psi g)

Temperature range: -60/+150°C (-76/+302°F)

Acts as a normal stop valve in closed position.

Housing and bonnet material is low temperature steel according to requirements of the Pressure Equipment Directive and other international classification authorities.

Exact capacity and setting of the valve can be calculated for all refrigerants by means of "DIRcalc^™" (Danfoss Industrial Refrigeration calculation programme).
