REMOTE BY-PASS VALVES FOR FLUID-LINK CATAMARANS

For larger vessels where manual activation of the manual by-pass valves (CatN8, 330C etc) are difficult, a remotely activated 12 or 24VDC bypass valve can be fitted. This allows alignment by the simple flick of a switch, and is adjusted by using the steering wheel and rudder angle indicators.

Valves come with blank female ports, and fittings are an additional cost. Valves need to be correctly selected to fit the tubing used in the installation.

LINEAR DRIVE CYLINDERS

The same valve with a NORMALLY OPEN configuration can be used to allow hydraulic linear drive cylinders to float when not being used by an autopilot.

RUDDER ANGLE INDICATORS

Quality rudder angle indicators for single or dual station with combined 12/24vdc voltage are available. Bezel diameter is 80mm.

AUTOPILOT ISOLATION VALVES

The 2-WAY PILOT is used to isolate the pilot pump from the main steering lines, and the 1-WAY PILOT is used to isolate the balance line. These two valve types are essential to maintain manual steering in the event of pilot pump failure or service.

LOCK VALVES

The 331C lock valve is a single double acting lock valve designed to prevent load motoring the helm unit. This should be used where the autopilot has a lock valve of it’s own, or to eliminate feedback from a highly active rudder.
The 318C lock valve is a dual double acting lock valve and should be used on all dual station installations using 103-107 helm units, unless feedback is required (see feedback options below).

These valves are available with various fittings and kits to make dual station installations very simple.

EXPANSION TANK KIT

Where the combination of helm size, tubing size, and run length result in a large oil volume in the system, it may be necessary to fit an expansion tank - particularly in areas where there is a large variation in temperature. This tank can be fitted to any of the model 103-107 helm units, and is usually located behind the console, out of sight - either higher or lower than the helm unit - eliminating any problems due to oil expansion.

OTHER FITTINGS

HyDrive provides a wide range of fittings to help make your installation complete. The chrome brass bulkhead fittings are a perfect solution to pass through fibre glass transoms and engine wells.

Copper, steel, and stainless steel tubing, and matching fittings -
are also available.
