XLC 330/430 PN 25

Flow control valve

The CSA model XLC 330/430 is a globe pattern hydraulically operated automatic control valve that limits the flow to a pre-set value, regardless of pressure variations. In case of flow rate lower than the required set point the valve will be fully opened. The valve is supplied with an orifice plate assembly, needed for the proper functioning and connected to the pilot.
