Cast basalt valve, cast basalt wear-resistant valve, cast basalt pipe valve, cast basalt plate manufacturer introduces that the sealing ring of cast basalt valve generally has two control modes: solenoid valve and mechanical valve. The working principle of the cast basalt valve determines that the sealing ring can be inflated only after the cast basalt valve is closed in place; The cast basalt valve can not be opened until the sealing ring is completely vented.
Because there is much dust in the service environment of cast basalt valve, it is easy to block the muffler on the fast exhaust valve, and the compressed gas in the sealing ring cannot be quickly eliminated, so it is cut by the moving valve core.
