L3S 3-way Control Valve

The Clorius L3S  3-way control valve is designed for regulating freshwater, cold and hot seawater and lubricating liquids. The compact L3S valve is used in conjunction with temperature regulators in control systems for cooling and heating of domestic premises, district heating, industrial processes or marine installations.

The valve components – valve body, seats and cone – are made of sea-water resistant gun metal RG 5. The valves are single seated. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Note: The design of the sizes DN 15 (½˝) and DN 20 (¾˝) is different from the bigger ones.

Without an actuator being connected, connection 2-1 is fully open and connection 3-1 completely closed by means of a spring. On increasing pressure on the spindle, the opening of the ports changes proportionally to the travel of the spindle, and when the spindle is pressed to the bottom, connection 3-1 is fully open and connection 2-1 completely closed.
