Subsea Ball Valves
Subsea Ball Valves are designed for reliable offshore operations in oil and gas exploration, production, and transmission, even at water depths of up to 1000 meters.
They are commonly used in subsea pipelines, risers, PLEM, PLET, and HIPPS applications, ensuring safe and efficient flow control under extreme conditions.
Subsea Slab Gate Valves
Subsea Slab Gate Valves are engineered in accordance with API 6DSS to deliver reliable isolation and long term performance in demanding offshore subsea environments.
Designed for oil and gas exploration, production, and transmission, these valves are suitable for water depths up to 1000 m and critical applications such as subsea pipelines, risers, PLEM, PLET, and HIPPS.
Frequently asked questions
Here are some common questions about Subsea Valves.
A Subsea Slab Gate Valve is a heavy duty isolation valve designed for offshore subsea oil and gas operations. It uses a slab style gate mechanism to provide tight shut off, even under high pressure, high load, and contaminated flow conditions.
These valves are designed and manufactured in accordance with API 6DSS, ensuring compliance with stringent requirements for subsea safety, performance, reliability, and long term durability in harsh offshore environments.
Subsea Slab Gate Valves are typically available from NPS 2” to 30” in pressure classes 150 to 2500, while Subsea Ball Valves are commonly supplied in NPS 2” to 24” with similar pressure class ratings, depending on project requirements.
A Subsea Slab Gate Valve is primarily used for on/off isolation with a straight through bore, making it ideal for pigging operations and high pressure isolation. A Subsea Ball Valve, on the other hand, uses a spherical ball to control flow and offers quick operation, tight shut off, and compact design, making it suitable for both isolation and control in subsea systems.
Yes, both valve types are engineered for subsea service and are suitable for water depths up to 1000 meters, with designs capable of withstanding high external pressure, corrosive seawater, and extreme operating conditions.
They are manufactured using high strength carbon steel, stainless steel, duplex/super duplex stainless steel, and special alloys, with corrosion resistant coatings and overlays to ensure long service life in aggressive subsea environments.
