API 6A Wellhead Hydraulic Gate Valve For Well Flow Control Service
The Mud Gate Valves or Mud Valves are applied for rigorous requirements of abrasive and erosive service conditions in oilfield applications, such as mud, cement, fracturing and water service. The mud gate valves are manufactured according to API 6A Specification. The Mud Gate Valves are available with 4 types of end connections: the Butt Welded connection, the Threaded connection, the Hammer Union connection, and the Flanged connection.
The hammer union ends mud gate valves are mainly used for drilling mud circulating system in oil field, it is used to control the flowing and stopping of mud. The hammer union ends mud gate valve seat and gate are sealed by means of parallelled Metal to Metal Sealing. Mud Valves end connections vary by sizes and pressure ratings based on concrete oilfield application requirements.
The mud valve is of reliability, high prssure and corrosion resistance, and can be used in the following working condition
1. Drilling standpipe manifold
2. Pump manifold block valves
3. High pressure mud mixing lines
4. High pressure drilling system block valve
5. Wellheads
6. Well treatment and fracture service
7. Production manifolds
8. Product gathering systems
9. Product flow line
