1. A significant switch position indicator: ball valve body, spheres, and handles an assembly unit, handle pointing in the direction of pipeline valve to open, handle the vertical pipeline direction valve is closed; Even the worm gear head with on/off indicator. 2. Locking devices design: in order to prevent switch operating errors, adopts the flat head stem in the switch position setting locking hole, to ensure that the Industrial Valves is in the right place. 3. Blow-out proof oriented type valve stem. Stem from the valve body inversion or prevent structure, and the sealing ring seal, even if there is a fire, packing damage, the valve stem protuberant part can also be closely contact with the body on the seal face, can effectively prevent the leakage and valve stem, reduce accident loss. 4. Antistatic design: using chromium nickel stainless steel spring and small ball sphere, conduction between the stem and valve body, thereby the non-metallic seat and ball friction electrostatic released in full. 5. Fire prevention structure: one thousand fire or burning of the abnormal heat up to soften PTFE, seat bearing ring can fire prevention sealing surface and sphere contact, sealing effect and accord with API607 and API6FA specification requirements. Fire safety design, precision machining in seat bearing surface inside a fire sealing lip, when Industrial Valves burning fire, fire prevention is formed between the sealing lip and the sphere of the metal to metal seal, valve packing gasket adopts temperature resistance of graphite materials, to ensure the valve no leakage 6 when the fire broke out. Automatic pressure release: the valve lumen stagnant medium when the abnormal pressure due to temperature increase, the seat outlet has the function of automatic relief, at the same time, according to need the valve can be installed on the relief valve, to ensure the body has the function of automatic pressure relief, ensure the security of the pipeline. 7. Seal of emergency care: due to the impurities or fire seat seal fails unexpectedly, greasing valve provides a connection to a quick note grease gun, convenient and quick to sealing grease injection to the valve seat sealing parts, reduce leakage. 8. Two-way seal fixed ball valve: the company develop two-way sealing ball valve series, USES the import and export bidirectional sealing, make more reliable sealing, the valve in any single pressure, lumen closed pressure ( No matter what kind of testing method) All can achieve zero leakage. Pneumatic ball valve of the sphere. Use upper and lower two root stem fixed. Job, fluid pressure doesn't make the ball seat, the seat will not deformation under too much pressure. Stem section with self-lubricating bearings, reducing friction, the switching torque is small, two seat adopts spring preload. Sealing using ptfe inserted into the steel, steel ring at the back is equipped with spring, guarantee the seat close to the sphere. When the valve lumen abnormal pressure higher than spring tension force, the seat back out of the sphere, achieve automatic relief effect, pressure automatic reset after the seat. For fixed ball valve structure of advanced nature of the seal performance is stable, easy operation service life is long, very suitable for long distance pipeline and pipeline. General ball valve has a full size and reducing two kinds of structure forms. Used for conveying post even, easy slagging medium pipeline ball Industrial Valves should be used on the full size, convenience of paraffin purging through on a regular basis. Used for conveying gases or physical properties similar to water medium should be used on the pipeline of reducing ball valve, because of its weight is about 30% lighter than the full bore ball valve, is conducive to reducing load pipeline, reduce the cost. The rotation of the ball valve is a kind of Angle is 90 ° class valves, sealed performance is good, Full bore ball valve) Discharge coefficient of flow resistance coefficient is small, simple structure, long service life, easy maintenance. Products are widely used in chemical, petroleum, textile, electricity, food, pharmaceutical, refrigeration, control system in papermaking industry.
