Clack 2572 WS1 Control Valve
High-performance control valve for water treatment systems with upflow/downflow regeneration, solid-state microprocessor, and reliable patented design for efficient softening and filtration.
Description
The Clack WS1 Control Valve is a durable and reliable valve system engineered for water treatment applications. Designed with a solid-state microprocessor, this valve provides easy programming and advanced functionality with three operational modes—meter immediate, meter delayed, or time clock delayed. It features double backwash for superior regeneration efficiency and optimal system cleaning.
This valve supports both downflow and upflow regeneration and is capable of up to 36 pre-programmed regeneration cycles. With its non-volatile memory, data and settings are preserved even during power interruptions. The system is built for high performance, using a patented piston design and one-piece expanding seal spacer stack assembly for consistent, leak-free operation.
Ideal for residential, commercial, and light industrial applications, the WS1 ensures efficient water treatment through precise flow control, consistent pressure management, and ease of maintenance.
