FRS40-1,6 FRS - 2-way valves, DN15-65
This product is discontinued
Flanged valves for heating, district heating and air handling systems. The valves are intended for use together with Regin’s RVAN actuators. Adapters are also available for adaptation to actuators of other brands. The valves are mainly intended for district heating and were primarily developed to replace the TAC valve STL. The valves (DN20…DN40 with kvs 0.6-4.0) are available in DIN-standard lengths as well and are then called FRSD…, for instance FRSD32-1,6. Standard FRS valve DN15 is already in DIN-standard.
