The Clorius Controls L1S 2-way control valve components spindle, seat and cone are made of stainless steel. The L1S valve body is made of gunmetal RG 5. The thread for the actuator connection is G1B ISO 228. The valve is single seated. The leakage rate is less than 0.05% of the full flow (according to VDI/VDE 2174). Without the actuator being connected, the Clorius L1S control valve is held in an open position using a spring. With pressure on the spindle, the valve will close. In connection with thermostats, pneumatic or electric actuators, the valve will close at rising temperatures. For cooling circuits, the valve can be used in conjunction with a reverse acting electric actuator. Alternatively, a reverse acting valve can be used with our self-acting thermostats. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.
