API 6A Valves
FET’s API 6A XL Gate valve was designed with simplicity in mind, both with bidirectional sealing capabilities and low pressure up-stream sealing capability below 300psi. The seat insert sealing design also reduces internal body/gate contamination and gates are standard with tungsten carbide hard facing.
Applications
FET XL Gate valve can be used in various applications, such as:
- Sweet/Sour Oil & Gas
- Wellheads
- Choke & Kill manifolds
- Emergency shutdown applications
- Fracturing
- Pipeline
