Bifold have successfully designed and manufactured subsea valves maintaining safety factors and reliable operation across the pressure range to over 15,000 psi / 1035 bar with an operating temperature range of -50°C to +140°C.
Designed to operate reliably on fluids with contamination levels greater than NAS 1638 Class 12, these true failsafe valves provide the option for reducing the sub-sea control module weight and cost, providing the customer with superior products for their application.
With a focus on safety and reliability in subsea control, Bifold’s directional control valves maintain safety factors on pull in and drop out voltage as well as de latch pressure, throughout the pressure range, but also during long term cycling (in cycles) and long term static hold tests.
Bifold’s production facilities based in the UK carry out extensive test programmes, including ISO 13628-6 compliance, endurance and corrosion testing, shock and vibration testing, high and low temperature storage and function testing and contamination resistance testing.
The Bifold sub-sea range includes Shearseal directional control valves, shuttle valves, pilot operated valves (ball seated and slide), solenoid valves with a range of connector options, check valves, relief valves, pumps, intensifiers, special valve products and control pod products.
