Features

Self-sealing check valves are designed according to standard BS1868 and ASME B16.34. Self-sealing check valves are mainly used in fossil fuel power plants at high temperatures and pressures. Compared to bolted valves, these valves provide bonnet joints. The absolute safety seal makes the self-sealing check valve provide closer service in valve maintenance in high temperature and high pressure environments.
