Harken single and multifunction valve panels are used by larger cruisers to control systems like backstays, boom vangs, and outhauls. Available as kits, single-function panels are offered with 2-liter reservoirs, multifunction panels with 4-liter reservoirs. Both panels come with pumps, handles, gauge, pressure relief, and release functions. Panels come standard with a 1- or 2-speed pump.
Multifunction panels can operate up to four cylinders remotely, with a selector handle choosing 1 of 4 functions. Valve panels feature an easy-to-read gauge and a finger-controlled knob for pressure release.
