Technical parameters and characteristics of the FLECKER 3900 control valve

The FLECKER 3900 series twin-piston industrial control valve is particularly suitable for large twin-tank systems configured for operation with one tank in use and one in reserve, or for simultaneous operation with alternating regeneration. It can work in tandem with a 1600 mm diameter softener tank, providing a continuous water output (with a pressure drop of 0.1 MPa) of 56.81 m³/h. The outer diameter of the pipe is typically 3 inches. The FLECKER 3900 control valve is designed for twin-tank systems with horizontally positioned pistons, with two pistons - one controls the regeneration process, and the other controls the switching of incoming and outgoing water. The valve body is made of lead-free brass. It can be configured for systems with two or more tanks without the need for additional valves. Suitable for boiler water softeners and other large industrial water softeners.
