Single-seated 2-way valves for modulating control of hot/chilled water in heating, ventilating and air conditioning systems. These valves are designed especially for flow control in hydraulic systems with high temperatures and pressures, such as district heating systems. It can also be used in combination with 300 N actuators M6410/M7410 as well as with 400 N actuators ML7430/35 and ML6435. Because of the pressure-balanced plug, the close-off pressure is equal to the system pressure. In combination with dedicated actuators the VDE..C-SV safety linear valves are approved according DIN EN 14597 and marked with CE0035 e.g. for district heating application.
