In a 6A gate valve, the seat seal application is crucial for ensuring tight shutoff, particularly in high-pressure and high-temperature environments, such as in the oil and gas industry. API 6A valves are manufactured following standards for wellhead and Christmas tree equipment, where the gate valve provides on/off control with a straight-through flow. Here’s an overview of key considerations for seat seal applications in a 6A gate valve.

The gate valve uses a flat or slab gate that moves perpendicular to the flow to open and close.

The seat seal forms a tight connection between the gate and the valve body. Some gate valves feature a metal-to-metal or resilient (soft) seal for added sealing reliability.

JST main uses material such as PTFE, PEEK, Elgiloy spring, 316ss spring for seat sealing. They are good for different working condition.

Proper seat seal application in a 6A gate valve ensures optimal performance, reduced leakage risk, and reliable shutoff capability in demanding environments.
