Product Description

Stainless steel self-sealing welded globe valve refers to a valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the disc, the change of the valve seat port is proportional to the stroke of the disc; the forged steel cut-off valve is It is widely used in water conservancy industry. As the basic control equipment of industrial piping system, its role is very important.

Product Structure Characteristics

The Stainless steel self-sealing welded globe valve must be visually inspected before installation. The nameplate of the valve should meet the requirements of the current national standard "General Valve Marking" GB 12220; for valves with a working pressure greater than 1.0 MPa and a cut-off function on the main pipe, they should be installed before installation. Carry out strength and rigorous performance test, and use it only after passing the test

Advantages

1.The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so the wear and scratches are not serious, the sealing performance is good, and the service life is long.

2.When opening and closing, the disc stroke is small, so the height of the Stainless steel self-sealing welded globe valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.

3.The opening and closing moment is large, and the opening and closing is more laborious. The headmaster of the opening and closing time.

4.The fluid resistance is large, because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
