Hard sealed forged steel ball valve

Hard sealed forged steel ball valve product features:

1. All components of this product are forged parts

2. Adopting a bottom mounted valve stem and an inverted sealing structure for the equipment

3. Adopting an embedded valve seat, with an O-ring installed behind the valve seat to ensure that the medium does not leak outside

4. The sealing surface is made of nylon 1010, which has a friction coefficient usually one-third of that of Babbitt alloy, making it a natural sliding material. But its bending strength, impact strength, and high ductility are comparable to those of metals.

One; wear-resisting; Due to the alloy steel spray welding of the valve core and alloy steel overlay welding of the sealing ring of the hard sealed ball valve, there will not be too much wear and tear during opening and closing. (Its hardness coefficient is 65-70):

Two; Good sealing performance; Due to the fact that the sealing of the hard sealed ball valve is manually ground until the valve core and sealing ring are completely aligned before use. So his sealing performance is reliable.

Three; Light switch; Due to the use of a spring at the bottom of the sealing ring of the hard sealed ball valve to tightly hold the sealing ring and valve core together, the switch is very light when external forces exceed the pre tightening force of the spring.

Four; Long service life: It has been widely used in various sectors such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, as well as in people's daily lives.
