Cast steel electric high-temperature ball valve for steam pipelines

Q941H-16 DN125Cast steel electric high-temperature ball valve for steam pipelinesIt is a new product developed by absorbing the advantages of different structures of ball valves, V-shaped valves, and track ball valves. The ball valve adopts a double eccentric sealing structure, which has low wear, low torque, good sealing performance, and long service life. The valve seat and hemisphere are treated with special hardening technology, which is particularly suitable for harsh working conditions and erosion resistance requirements.

Features:

1. Due to the fact that the valve core of the hard sealed electric ball valve is spray welded with alloy steel and the sealing ring is welded with alloy steel, the hard sealed electric ball valve will not experience significant wear during opening and closing. (Its hardness coefficient is 65-70):

2. Good sealing performance, as the sealing of the hard sealed electric ball valve is manually ground until the valve core matches the sealing ring before use. So his sealing performance is reliable.

3. The switch is light. Due to the use of a spring at the bottom of the sealing ring of the hard sealed electric 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.

4. Long service life, it has been applied in various sectors such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, and people's daily lives.

Q941H-16 DN125Cast steel electric high-temperature ball valve for steam pipelinesSelection principle:

1. For the main pipelines of oil and natural gas transportation, those that need to be cleaned and buried underground, full bore and fully welded ball valves should be selected; For ball valves buried on the ground, choose full bore welded connections or flange connections; Branch pipes shall be connected by flanges or welding, with full bore or reduced bore ball valves.

2. Flange connected ball valves are used for the transportation pipelines and storage equipment of finished oil products.

3. Floating ball valves with flange connections and internal thread connections are selected for the pipelines of urban gas and natural gas.

4. In the oxygen pipeline system of the metallurgical system, it is advisable to use fixed ball valves that have undergone strict degreasing treatment and are connected by flanges.

5. Low temperature ball valves with valve covers should be selected for pipeline systems and devices for low-temperature media.

6. On the pipeline system of the catalytic cracking unit in the refining unit, a lifting rod ball valve can be selected.

7. In the equipment and pipeline systems of corrosive media such as acid and alkali in chemical systems, it is advisable to use all stainless steel ball valves made of austenitic stainless steel with polytetrafluoroethylene as the valve seat sealing ring.

8. Cast steel electric high-temperature ball valves can be used on pipeline systems or devices for high-temperature media in metallurgical systems, power systems, petrochemical plants, and urban heating systems.

9. When flow regulation is required, a regulating ball valve with a V-shaped opening, driven by a worm gear, pneumatic or electric, can be selected.
