• Independent gas injection and production channels formed by optimizing the wellhead structure 
• Monitoring wellhead pressure and temperature, and realizing automatic safety control through surface safety valve and underground safety valve Designed with the functions of connecting the well killing, blowout and testing pipelines
• Higher reliability and operability ensured through low torque of gate valve and metal-to-metal sealing 

• The all-metal sealed device is suitable for working in conditions of high pressure, corrosion and other harsh conditions Stable and reliable in long-term use, with a long service life
