The Clorius L1SBR (reversed acting) 2-way control valve is mainly designed for the regulation of cooling water and lubricating liquids. The L1SBR balanced valve is used in installations where the system pressure necessitates a closing force greater than available in the actuator programme for a standard single-seated valve, and where the leakage rate for a double-seated valve is unacceptable. The valves are installed combined with Clorius self-acting thermostats, pressure differential regulators or electric actuators for regulation in industrial plants, industrial processes or marine installations – especially in control systems for cooling. Design The valve components – spindle, seats and cone – are made of stainless steel. The valve body is made of gunmetal RG 5. The thread for the actuator connection is G1B ISO 228. The valve is single-seated, balanced. The leakage rate is less than 0.05% of the full flow (according to VDI/VDE 2174). Function Without the actuator being connected, the valve is held in a closed position by means of a spring. With pressure on the spindle, the valve opens. In connection with our thermostats, the valves will open at rising temperatures. In connection with our electric actuators, the valves will either close or open, depending on the application. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.

The Clorius G3FA 3-way control valve is designed for regulating freshwater, lubricating oil and other liquid media. The G3FA 3-way control valve is designed for use in conjunction with large industrial processes, district heating and marine installations, e.g. cooling of main and auxiliary engines. Is used in conjunction with Clorius valve motor type AVM/AVF 234 or Clorius pneumatic actuators. Design The valve components (seats and cone) are made of alubronze, the spindle of stainless steel. The valve body is made of nodular cast iron and the valve flanges are drilled according to EN 1092-2 (JIS B 2210 option). Tight between port 1(AB) og 3(B) is optional. Function The valve cone is firmly connected with the motor spindle. When the valve cone is in the one extreme position by draw on the spindle, connection A-AB is kept fully open and connection B-AB is fully closed. In the other extreme position connection A-AB is fully closed and connection B-AB is fully open. In the intermediate positions, the opening degrees change proportionally.
