INTRODUCING THE SS231...
The SS231 is a piston-sensed medium-flow subsea pressure regulator. With a balanced main valve as standard it provides stable control under varying inlet pressures.

Operating at depths of up to 3,000 metres (10,000ft), the SS231 uses either the external seawater pressure as a reference or works within a sealed chamber to remain completely unaffected by atmospheric conditions.

APPLICATIONS:

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 MP35N spring offers excellent corrosion resistance
Remote control options available
