CHANGE IN ORDERING CODE FOR DAPRV PRESSURE REDUCING AND RELIEF VALVES

As of July, the code designations of the DAPRV series pressure reducing and relief valves have been changed. The technical parameters remain unchanged. The original ordering code DAPRV-RET-DN15-PN25 is supplemented with additional characters for more detailed specification. Example of the new marking: DAPRV-REF-N-DN15-PN16-1-6. Detailed information is included in the datasheet. Another new feature of these valves is the EC1935/2004 certification. This is a European regulation for materials and valves intended for the food industry.

NEW FLAMESAF EMERGENCY PRESSURE RELIEF VALVE - 942-MW

A new product from BS&B - the FlameSaf® emergency pressure relief valve model 942-MW for preventing overpressure caused by flammable gases and vapours inside the tank. Pressure relief valves use fluoropolymer or elastomer diaphragms to provide a seal between the lid and seat. Combined with a 10 percent full stroke, the results are reliable and accurate even with minimal pressure changes. Another advantage is the optimized operating parameters, which are close to the Maximum Allowable Working Pressure (MAWP). The 942-MW pressure relief valve has been tested by a notified body and is certified according to 2014/34/EU (ATEX). The valve also meets the requirements of API 2000 and ISO EN 28300 standards.

REALIZED PROJECTS

KNIFE GATE VALVES WITH AUMA ELECTRIC ACTUATORS

An interesting project with a customer in the building materials industry was carried out in several phases at the turn of 2020 and 2021. In June, we added another set of valves for a wastewater treatment plant. After a successful exit inspection and test, we shipped the L20 stainless steel knife gate valve assemblies with AUMA SA07 electric actuators.
