Series 451bHF

Universal high performance safety valve made of extremely corrosion resistant stainless steel with stainless-steel-bellows, to meet the highest demands. Suitable and approved for heating plants and cooling- and chilling plants. The sizing of the valve is based on the heating output of the boiler. In the case of indirectly heated heating generators and closed chilling circuits this is based on the flow volume of the expansion water.
