The main system is connected with the power transfer unit (PTU) through the
PTU manifold (1013GM). The PTU manifold also has outputs to other consumers.
The connections are:
- one inlet/outlet from/to the PTU,
- one inlet from the HP manifold,
- one outlet to the HP manifold,
- one outlet to consumers (downstream of the priority valve 1064GM),
- one outlet to the normal brake system (Ref. 32-00-00).

A solenoid valve (1012GL) installed on the PTU manifold controls (together with the equivalent Yellow system valve) the flow of fluid to/from the PTU. A single pushbutton (P/B) switch in the flight compartment controls the operation of the two solenoid valves. When the P/B switch is operated, both solenoid valves are energized and the supply of fluid to/from the PTU is stopped.
The system priority valve (1064GM) is installed on the PTU manifold. It stops the supply of fluid to non-essential consumers if the system pressure is too low. The priority valve closes at 127 bar (1841.9787 psi) to 130 bar (1885.4901 psi) and opens at 135 bar (1958.0089 psi) to 140 bar (2030.5278 psi).
Two check valves (1093GM and 1094GM) are installed on the PTU mainfold. They control the flow of fluid in the manifold. Also installed on the PTU manifold is a solenoid valve which controls the flow of fluid to the normal brake system (Ref. 32-00-00).

A solenoid valve on the HP manifold controls the flow of fluid to the LMS manifold. The solenoid valve is operated from the maintenance panel in the flight compartment. The LMS manifold (1146GM) makes it possible to measure the internal leakage of groups of consumers. The HP supply is divided into three separate outputs, one to each of the following:
-
flight controls in the LH wing,
-
flight controls in the RH wing,
-
flight controls in the tail section.
Measurement of internal leakage is done with a ground hydraulic supply and a
flowmeter (Ref. 29-19-00).
