Spec: DSV are 3-way valves designed specifically for use with double safety valve systems, but which are also suitable for other purposes. The valves are equipped with threads for nipple/flange connection, which permit easy inspection or replacement of safety valves. DSV are designed to meet the strict quality demands on refrigeration installations specified by the international classification societies. In systems where the pressure drop over the double stop valve is restricted to max. 3% (incl. upstream line) according to prEN13136, it is necessary to install the DSV 32 in conjunction with two SFV 15 or two SFV 20. DSV are carefully selected to establish favorable 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
