2.The FLECK 2750 control valve is a single-piston industrial control valve suitable for use in single-tank systems, filters, boiler water softeners, and other industrial water softening applications.
Performance Features:
a. Horizontally arranged piston
b. Valve body made of lead-free brass
c. Compatible with a hard water bypass piston, which automatically blocks hard water during regeneration, eliminating the need for additional valves
d. High backwash flow rate
e. Valve can be configured for manual operation
f. Can be paired with a dual-tank system (one in use, one standby), requiring additional valves to achieve this configuration.
