HDL Digital Piston Valves

NSF 44 Certification Logo

Hankscraft Runxin takes the next step forward in mechanical control design with our HDL digital piston valves. These valves have improved construction and a lightweight design, with added features to give you increased flexibility, higher performance, and easier operation and maintenance.

HDL valves offer an intelligent preset reference mode, 3-button programming with adjustable cycle settings, quick-connect drain with optional offset, and an automatic reset feature with battery backup. These valves combine the interfaces of our HL and HD valves, providing even more versatility during setup. HDL valves are available in metered (programmable to extended metered) and filter versions. They also feature an L bracket design for hassle-free operation and maintenance.
