Hand operated regulating valve

Type REG-SA and REG-SB 65

Designed for regulation purposes in liquid and expansion lines, suitable for MWP up to 65 bar

REG-SA and REG-SB are angleway and straightway hand regulating valves, which act as normal stop valves in closed position.

The valves are available in two di€erent 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/heat pump 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.

Hand operated regulating valve, type REG-SA and REG-SB 65

Features

•Modular Concept:

◦Each valve housing is available with DIN and ANSI butt weld connection and in several di€erent sizes.

◦Possible to convert REG-SA or REG-SB to any other product in the FlexlineTM SVL family (shut-o€ valve, check & stop 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.

•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 Coolselector™.

•Classification: DNV, CRN, BV, EAC etc. To get an updated list of certification on the products please contact your local Danfoss Sales Company.

•Equipped with 42CrMo5 bolts to withstand high pressure.

•Service kits with replacement O-rings for R717 Heat Pump and R1270 Propylene include separate ID-ring for ID of application

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specific refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Hand operated regulating valve, type REG-SA and REG-SB 65

The cone

The valves are available in two di€erent versions – REG-SA with an A cone and REGSB with a B cone. The A cone is designed for expansion lines, while the B cone is designed for regulating purposes e.g. liquid lines.

The valve cone is designed to ensure perfect regulation and provide an extensive regulating area. Irrespective of the refrigerant used, it is easy to obtain the correct capacity. A cone seal ring provides perfect sealing at a minimum closing momentum.

The valve cone can be turned on the spindle, thus there will be no friction between the cone and the seat when the valve is opened and closed.

Spindle

The spindle is made of polished stainless steel, which is ideal for O-ring sealing.

Packing gland - REG-SA and REG-SB

The “full temperature range” packing gland ensures perfect tightness in the whole range: -60 °C /+150 °C (-76 °F / +302 °F). The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice.

Installation

Install the valve with the spindle up or in horizontal position. The flow must be directed towards the cone.

The valve is designed to withstand high internal pressure. 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 product instruction for REG-SA and REG-SB.

ID ring for special application

After converting a REG-SA/SB (DN 10-40) valve for Heat Pump/Propylene applications (replacing O-ring) the color marked ID tag included in the service kit must be fixed to the valve as shown in figure to the right.

The ID tag indicates the special application and identifies the installed O-ring.
