Flow Control Valves

Flow valves with fixed screen or adjustable throttle valves influence the volume flow depending on temperature and pressure. With twin throttle check valves, the throttle valve is effective only in one direction of flow. Two parallel throttle valves operate in one flow direction as a flow divider valve and in the opposite direction as a flow combiner valve. The flow control valve, the throttle valve and the flow divider valve are valve cartridges, while the throttle check valves are plate valves. With the 2-way flow control valve or the 3-way flow control valve, load-compensated flow rates are infinitely adjustable. The 2-way flow control valve is available in combination with a check valve.
