Soft Seat Ball Valve
Soft seated ball valves share such characteristics with tight configuration, stable sealing, and convenient repairing. The sealing surface of soft seated ball valves maintains a closing position between ball’s surfaces without any flushes by the medium, employed in the working mediums of water, solvents, acids, gas, etc. as well as mediums under the tough working environment such as oxygen, methane, ethylene, etc.

Applications & Features:
Soft seats are typically composed of thermoplastic components like PTFE. These valves are appropriate for applications in which chemical compatibility is crucial, and in situations where having the tightest seal is essential for customers’ decisions confronted with the actual working environment.
In general application, the soft seated ball valves are suitable for a clean fluid and not recommended for a dirty fluid. This is reasonable since some particulate may damage the soft seat material and cause leakage. In terms of the required torque to operate the ball valves, the soft seated ball valve will have a lower torque rather than metal seated ball valves.
Soft Seated Valves vs. Metal Seated Valves
Deciding on the right seat material can be a difficult decision when it comes to ball valves because you’ll have several options. Determining factors you will need to consider include the materials used in construction, the appropriate size, and the type of design features including V-port, bleed, double bock, 1, 2, or 3 pieces, etc. An even more important consideration is the seat type.
Having a complete understanding of the process conditions should be the starting point when it comes to choosing seated valves.
