L1S 2-way Control Valve

L1S 2-way Control Valve

7389

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.

VTM 25 Turbine Flow Sensor

VTM 25 Turbine Flow Sensor

7807

The SIKA VTM 25 turbine flow sensor is made for flow measurement or dosing applications for liquids. Because of the very compact design, the extensive measuring range and the convincing precision of measurements, almost unlimited applications are possible. The sturdy bearing materials – sapphire and tungsten carbide – also guarantee an exceptionally long endurance. The liquid flowing into the SIKA VTM 25 turbine flow sensor is split into individual jets by the guiding blade. These jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets and a Hall effect sensor detects the rotation of the rotor. A flow-proportional frequency signal (square-wave signal) is made available. The construction of the guiding blade and rotor enables to realize the very low start-up flow values.
