SubSea Valves
Subsea Valves are used in sub-marine environments and forms an important part of a subsea flow infrastructure that can be installed in depths from shallow water usually down to a depth of 30 meters to deep water to a depth down to 4000 meters. Various industries use subsea valves with the oil, sea and gas sectors accounting for the majority of applications.
Subsea Isolation
Provides a range of Subsea Isolation valves and actuators to the oil and gas offshore industry, with a focus on subsea applications. Products include gate, ball, and check valves in sizes from 0.5-in. (1.3-cm) up to 48-in. (1.2 m) and larger, in pressure classes up to 15,000 psi and 20,000 psi (1,034/1,379 bar).
Key Considerations
Given the extreme external environmental factors that can be encountered at these depths, the consideration for subsea valves, over regular land based valves include:
- Waterproofing
- Increase in ambient pressure measured in decibars (dbar)
- Construction materials that are able to withstand long-term corrosion effects from high salt content seawater
