The Hy-Pro V4-40 G3/8 sectional valves are a standard in winch applications across the marine industry. It has control options for either rotary lever or by-pass flow control in conjunction with excellent spool metering to precisely control the winch speed. The valves feature environmental protection of external and internal components to withstand harsh on-deck conditions. The V4-40 valve is suitable for flows up to 40 L/min at 250 bar.
The Hy-Pro rotary lever has been developed specifically to enable the operator precise control of motors and cylinders. The lever moves through a 130° arc and works by means of a scroll which converts the rotary action of the lever into axial movement of the spool. The centring mechanism has a friction detent feature which positively holds the spool in neutral then maintains the selected position.
