HD/HDL

DIGITAL PISTON VALVES

The next step forward in mechanical control design.

Fully adjustable ceramic valve for residential and light commercial use.

Our HD and HDL digital piston valves have improved construction and a lightweight design. These valves now come with added features to give you increase flexibility, higher performance, and easier operation and maintenance. HD and HDL valves offer an intelligent preset reference mode, 3-button programming, and adjustable cycle settings. These valves also feature a quick-connect drain with optional offset, and an automatic reset feature with battery backup. Both valves are available in metered (programmable to extended metered) and filtered versions.
