XS Scuba Over Pressure Valve is designed to help you prevent the rupture of your lift bag or BCD in case they get over-inflated. The valve works by automatically compressing the valve spring and relieving the pressure.
The durable construction and the use of non-corrosive plastic ensure that the OPV will withstand a lot of wear and tear. The valve also includes a pull cord with plastic knob for easy use.
