Hard seal eccentric semi-ball valve and flanged gate valve belongs to the same type valve. The difference is that its closure member of Hard seal eccentric semi-ball valve is a sphere, sphere around the center line of the body as a rotation to achieve a kind of open and close the valve.
The specifications of Hard seal eccentric semi-ball valve are:
1. Design and Manufacture: API6D/GB/T 12237
2. Face to face: API 608, API 598, API607/GB/T12221
3. Flange connection: ANSI B16.5/ JBT/79
4. Temperature: Not beyond 160oC
5. Nominal pressure: 0.6-16MPa
6. Size: 1"-80"
7. Medium: Liquid, oil, serous, particles of slag, air
8. Material: WCB
9. Metal sealing semi-ball valve, electric actuator ball valve, float valve, actuator ball valve
The structural features of Hard seal eccentric semi-ball valve are:
1. Zero friction when opening and closing. This function completely solves the traditional valve for sealing surface friction each other and affects the sealing problem.
2. The valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost.
3. Single valve seat design. It eliminates the influence due to abnormal pressure valve lumen medium use safety problems.
4. Low torque design. Special structure design valve rod equipped with a small handlebar to open and close valve.
5. Wedge-shape sealing structure. Valve adopts valve rod as mechanical force, ball wedge pressure into valve seat to seal and make the valve sealing is not affected by pipeline differential pressure change to ensure its reliable sealing in any working condition.
6. Sealing surface self cleanness structure. When sphere leaves valve seat, fluid along the sphere seal face into evenly through 360 ° In pipeline, not only remove the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the seal to ensure its cleanness.
