The BSTU provides a controllable pressure between 7 and 210bar to be applied via the pressure out connection. The pressure developed is monitored by a transducer which may
be connected to the subsea control unit if required, and also an analogue subsea gauge. The applied pressure may be switched off / locked in by means of the ram operated ball valve.

All the components are mounted on an aluminium base plate which should be secured to the host vehicle structure in an accessible location. There are no specific spatial orientation requirements. Hydraulic connections are ¼” Swagelok male thread. The ram is operated by an ROV spare bi-directional function (210bar max). The supply pressure may be acquired anywhere suitable from the host vehicle circuit (210bar max). The drain line should be connected as directly as possible to the ROV return circuit to minimise return line losses.
