Optional pressure gauge to monitor hydraulic supply and identify positive isolation
Anodes protect against corrosion in extended deployments
Proven robust design
Designed for ROV placement and operation
Simple to use
The 4-Valve Block & Bleed Panel is designed to direct pressure to a designated hot stab port and provide isolation for testing operations. The panel allows pressure to be directed to both TMT ISO13628-8 2-Port Type A or Type B hot stabs. Both ports can then be vented to sea or back to tank, depending on client requirements.

The panel is typically mounted on an ROV’s left-side manipulator arm to allow easy valve operation by a right-side 7function manipulator arm. A hot stab receptacle with blanking plugs can also be integrated, allowing subsea circuit pressure testing.
Pressure readings can be achieved by adding an analogue subsea pressure gauge or a digital Keller Pressure Transmitter for surface read out.
The panel is frequently used with the following TMT tooling products:
• TMT ISO Type-A 2-Port Hot Stab: TMT-NSS-012
• TMT ISO Type-B 2-Port Hot Stab: TMT-NSS-180
• TMT Backpack Fluid Skid: TMT-NSS-183
• TMT IOX Junction Box: TMT-NSS-519
