The following is an introduction to ball valves
1. Fully welded ball valve is a kind of on-off control valve, the valve body is in the form of full welding, the valve is not easy to produce deformation and aging resistance.
2.The machining precision of the sphere is high, and the machining process is tracked by an advanced computer detector. The fine grinding of carbon steel + ENP or stainless steel sphere can ensure the freedom of switching and reliable operation for many years.
3. The valve seat adopts the mixed design of metal and rubber, and is equipped with emergency sealing grease filling structure, the sealing is safe and reliable.
4. The utility model has the advantages of compact structure, light weight, easy heat preservation, easy installation, good sealing performance and long-life operation in the case of frequent operation and impurities. It is widely used in natural gas, petroleum, heating, chemical and thermoelectric pipe networks and other long-distance pipeline fields.
a) Unique, the metal seated ball valve with patented single-seat ball valve design. It has a flat spring set acting through a hard-faced bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low delta P.
b) Metal seated ball valve proven in qualification tests and field operation to be solids-proof, even for the toughest applications on slurry service with solids particles.
c) Tightness rates: Allowable leakage rate at full Delta P: ASME/ FCI 70-2 Class VI/V. Tighter shutoff available upon request.
The leakage rate also can be customization from end-user request
d) The metal seated ball valve with standard extension bonnet/stem, whose design base on the different temperature range.
e) Uni-directional or bi-directional sealing
The valve plate of the high-temperature sanitary ball valve and the sealing surface of the valve seat are oblique conical structures with temperature and corrosion-resistance alloy material welded on the inclined cone surface of the valve plate. These specialized alloys allow the valve plate and seat to withstand routine wear and tear caused by corrosive chemicals and abrasive mediums.
The spring fixed between regulating ring pressure plates is assembled together with the regulating bolt on the pressure plate. This structure effectively compensates for the tolerance zone between the sleeve and the valve body as well as the valve stem's elastic deformation from the system's high pressure. These components solve the valve's sealing problem in the process of two-way interchangeable medium transportation.
