The valves are especially designed for protection of components against excessive pressure and to meet the strict quality demands and safety requirements for industrial refrigeration installations, specified by international classification societies.

Product Ranges:
SFA safety relief valves, back pressure dependent
SFA 15 are safety relief valves - back pressure dependent - in angleway execution, specially designed for protection of vessels and other components against excessive pressure. The valve is designed to meet the strict quality demands and safety requirements for refrigeration installations, specified by the international classification societies.
The valve is recommended as an external and internal safety relief valve in refrigeration plants. The spring housing is closed tightly to avoid refrigerant leakage.
The valves can be delivered with set pressures between 10 and 40 bar g (145 and 580 psi g).
Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve, are also available.

SFV safety relief valves, back pressure dependent
SFV 20 - 25 are safety relief valves - back pressure dependent - in angleway execution, specially designed for protection of vessels and other components against excessive pressure.
The valve is designed to meet the strict quality demands and safety requirements for industrial refrigeration installations, specified by the international classification societies. The valve is recommended as an external and internal safety relief valve in refrigeration plants. The spring housing is closed tightly to avoid refrigerant leakage.
The inlet flow diameters of the valves are: - 18 mm (3/4 in.) for SFV 20, and - 23 mm (1 in.) for SFV 25.
The valves can be delivered with set pressures between 10 and 25 bar g (145 and 363 psi g).
Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve, are also available.

BSV safety relief valves, back pressure independent
BSV 8 is a safety relief valve - back pressure independent, designed for protection of small components against excessive pressure.
BSV 8 is an angleway valve that can operate with a very high back pressure. It is designed to meet the strict quality demands and safety requirements for refrigeration installations as specified by the international classification societies.
As the valve is back pressure independent, it is recommended for use as an internal safety relief valve. However, it can also be used as an external safety valve. The spring housing is tightly sealed to avoid refrigerant leakage.
The inlet flow diameter of the BSV 8 is 8.0 mm (5/16 in.).
BSV 8 is available with set pressures between 10 and 25 bar g (145-363 psi g), and also with individually assigned ”TÜV pressure setting Certificate”.

POV safey relief valve, pilot operated
POV safety relief valve is used in conjunction with the BSV back pressure independent safety valve and is specifically designed for protecting compressors against excessive pressure.

DSV change-over valve
DSV are 3-way valves designed specifically for use with double safety valve systems, but are also suitable for other purposes. The valves are equipped with threads for nipple/flange connection for easy inspection or replacement of safety valves.
DSV are designed to meet the strict quality demands on industrial refrigeration installations specified by the international classification societies.
DSV valves are carefully designed to establish favourable flow conditions. The valve cone is designed to ensure perfect closing. Even a light tightening of the valve will close the valve effectively. All valves are equipped with vented cap
