DSV 1 / DSV 2 / DSV 10
DSV 10, DSV 1 and DSV 2 are change-over valves, which are designed to meet all industrial refrigeration application requirements. DSV valves are designed specifically for use with double safety valve systems. The valves are designed to give favorable flow characteristics and are easy to dismantle for servicing. The valve cone is designed to ensure perfect closing, even with minimum torque the valve will close effectively. All valves are equipped with vented cap and nipple/flange connections, which permit easy inspection or replacement of safety valves.
