Factory direct supply various types of high-quality brass drain valve drain valve tank truck

The drain valve is homegrown, may shelf various models of various specifications Threaded drain valve. Welcome to inquire: 18606751503 (Hui) release valve means valve functions as a drain valve can function, such valves can have a lot of, ah, shut-off valve can, ball can be, butterfly valves can, gate can. Shut-off valve, also known as stop-gates, is the most widely used of a valve, the reason it's popular is due to the process of opening and closing between the sealing surface friction is small, more durable, opening height is not easy to manufacture, repair convenient, not only for low-voltage, and suitable for high pressure. Its closure principle is to rely on the valve lever pressure on the valve sealing surface and the seat sealing surface snug fit to prevent the media circulation. Shut-off valve can only medium-way flow. Directional installation. Its structure is greater than the length of the valve, and fluid resistance, long-term operation, the sealing reliability is not strong.
