Safties in steering gear

1. Shock Relief Valve: Opens 15 ~ 20 % higher than working pressure
2. By-pass Valve        : Opens 20 ~ 30 % higher than working pressure
3. Line Relief Valve   : Opens 40 ~ 50 % higher than working pressure
4. Emergency power supplies to one motor.
5. Steering gear room bilge alarm.

6. Steering gear compartment drain valve spring loaded non-return.
7. Alarms: Alarms should be audible and visible in the both control stations (WH & ECR)
a) Single phasing alarm - SOLAS.
b) Motor overloading 100% - SOLAS.
c) Power failure.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
