1. The FLECK2900 control valve is a double-piston industrial control valve suitable for use in dual-tank large systems, multi-tank systems, filters, boiler water softeners, and other industrial water softening applications.
1. Performance Features of the FLECK2900 Control Valve:
a. The piston is horizontally arranged
b. There are two pistons, one for controlling the regeneration process and the other for switching water inlet and outlet
c. The valve body material is lead-free brass
d. It can be equipped with a hard water bypass piston without the need for additional valves
e. It can be configured as a dual-tank system (one in use and one as backup) without the need for additional valves to achieve this
2. Product Features of the FLECK2900 Control Valve:
● Uses dual control hydraulically balanced pistons to achieve separate regulation of regeneration and water inlet/outlet switching
● Widely used in commercial/industrial systems with superior performance
● Can be used with a single tank or configured as a dual-tank system
● Can be configured for 36" diameter water softening systems
● Can be set for 7 or 12-day time-triggered or flow-triggered regeneration
● The valve body material is lead-free brass, which is strong and can withstand high pressure
● Can be equipped with a hard water bypass piston
3. Options for the FLECK2900 Control Valve:
● Can be used as a backwash filter valve
● Flow-triggered regeneration
● Can be equipped with a hard water bypass piston
● Electronic controller (NT, ET controller, Systemax controller)
● Operating valve controller
● Auxiliary switch
● Can be used in hot water systems with a temperature limit of ≤180°F (82°C) for time-based models and ≤150°F (65°C) for flow-based models
● Can be configured for manual regeneration control
● Environmentally friendly enclosure
● Can be used for counter-current regeneration
● Can be installed in a side-mounted configuration
