Hand-operated regulating valves in stainless steel Types REG-SA SS and REG-SB SS Pr es su re
In certain specific areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion. Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection. REG-SA SS and REG-SB SS are angle-way and straight-way hand-operated regulating valves, which act as normal stop valves in closed position. 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. The valves are equipped with vented cap and have internal backseating enabling the spindle seal to be replaced with the valve still under pressure.

Frequently Asked Questions
What refrigerants and gases are these valves compatible with?
They are applicable to HCFC, HFC, R717 (Ammonia), R744 (CO), Propane, Butane, Iso-Butane, and Ethane.
How is internal backseating achieved on the valve?
The valves have an internal backseating feature that enables the spindle seal to be replaced even when the valve is still under pressure.
What are the operating temperature limits?
The valves can operate in a temperature range of –60°C to +150°C (–76°F to +302°F).
What types of flow mechanisms and connections are offered?
They come in Angleway (A) or Straightway (STR) versions and offer Butt-weld DIN (EN 10220) connections.
