Product Overview SS691

INTRODUCING THE SS691...
The SS691 is a piston-sensed low-flow subsea pressure regulator with ceramic seating for water-based hydraulic oil applications and systems. With the balanced main valve option it can provide stable control under varying inlet pressures and cope with higher flow rates.

Operating at depths of up to 3,000 metres (10,000ft), the SS690 uses either the external seawater pressure as a reference or works within a sealed chamber to remain completely unaffected by outside conditions.

SS691 Features

Suitable for deep waters down to depths of up to 3,000m (10,000ft)
Anti-tamper locking cap prevents unwanted pressure adjustments
Very high strength Elgiloy® spring offers excellent corrosion resistance
Remote control options available
