BS-13 Control Reservoir with Charging Valve - Replaces R-13

The BS13 control reservoir with charging valve is the replacement for the Hynautic R13 hydraulic engine control reservoir used to maintain extra fluid capacity and a constant pressure head for the system.

This vertical reservoir assembly is used in Hynautic hydraulic engine control systems where the charging valve regulates fluid flow at the bottom of the reservoir. The reservoir supports up to four stations, uses a visible sight glass and pressure gauge for routine checks, and helps compensate for fluid expansion and contraction as operating temperatures change.

Technical Specifications

The BS-13 follows the function of the original R-13 integrated reservoir by maintaining extra hydraulic fluid and a constant pressure head for the engine control system. Fluid flow to and from the reservoir is regulated by the charging valve below the tank, which helps keep the system under pressure while controlling expansion-related pressure changes.

System function Maintains extra hydraulic fluid and a constant pressure head for Hynautic engine control systems so the controls stay pressurized during operation.
Charging valve role The charging valve below the reservoir regulates fluid flow and helps prevent excessive pressure caused by fluid expansion as the system warms up.
Inspection features Uses a pressure gauge on top and a clear sight glass so fluid level and reservoir pressure can be checked quickly during service.
Installation orientation The reservoir should be mounted vertically with the pressure gauge on top and with easy access to the sight glass, air filler valve, fill port, and charging valve.
Fluid requirement Use HA5455 Hynautic shift and throttle control fluid only. Do not use steering fluid or stop-leak type antifreeze in the control system.
Build note Each BS-13 replacement reservoir is pressure tested before shipment to verify it meets factory specifications.

Direct R-13 Replacement Built as a new replacement reservoir for original Hynautic R-13 control reservoir installations.
Pressure-Regulated The charging valve and pressurized reservoir help stabilize the system as fluid expands and contracts with temperature.
Easy Routine Checks The top gauge and clear sight glass make it easier to monitor pressure and fluid level during normal maintenance.
Applications and Installation Notes

The BS-13 is used in Hynautic hydraulic engine control systems on pleasure craft, work boats, and commercial fishing boats where a pressurized control reservoir is required. It is intended for systems that originally used the R-13 style integrated reservoir with charging valve.

Install the reservoir in an accessible engine room location and keep it vertical with the pressure gauge on top. The sight glass should remain easy to read, and the operator should have access to the air filler valve, fill port, and charging valve. During routine checks, the fluid level should generally remain around one-half to two-thirds of the sight glass and reservoir pressure should typically stay in the 70 to 90 PSI range.

Frequently Asked Questions

Does the BS-13 replace the original Hynautic R-13 reservoir?
Yes. The BS-13 is sold as the replacement for the Hynautic R-13 control reservoir with charging valve.
What does the charging valve do?
The charging valve regulates fluid flow to and from the reservoir, keeps the system under pressure, and helps control pressure changes caused by fluid expansion as the system warms up.
What fluid should be used in this reservoir?
Use HA5455 Hynautic shift and throttle control fluid only. Do not use standard steering fluid or stop-leak type antifreeze in the engine control system.
How should the reservoir be mounted?
Mount it vertically with the pressure gauge on top. The sight glass, fill port, air filler valve, and charging valve should all remain accessible for inspection and service.
What pressure and fluid level should I look for during maintenance?
Reservoir pressure typically operates in the 70 to 90 PSI range, with the system normally charged around 80 PSI. Fluid level should usually stay about one-half to two-thirds of the sight glass.
