Brief introduction of J61Y forged steel self sealing stop valve

Forged steel self sealing stop valve refers to the valve whose closing part (disc) moves along the center line of the valve seat. According to this moving form of the disc, the change of the valve seat opening is in direct proportion to the disc stroke. Because the valve stem of this kind of valve has a relatively short opening or closing stroke, and has a very reliable cut-off function.

Advantages of forged steel self sealing stop valve

1. The structure is simple, and the manufacturing and maintenance are convenient.

2. The working stroke is small and the opening and closing time is short.

3. Good sealing, small friction between sealing surfaces and long service life.

Disadvantages of J61Y forged steel self sealing stop valve

1. The fluid resistance is large, and the force required for opening and closing is large.

2. It is not suitable for media with particles, high viscosity and easy coking.

3. Poor regulation performance.
