Brand Innovation Model Smart Ball Material Stainless Steel Connection Type Thread Structure Fixed ball valve suitable for medium water pressure environment Pressure Standard GB-way valve flow direction characteristics: a; abrasion resistant; the seal valve spool is steel spray, sealed ring is steel welding, seal valve does not produce so much wear and tear at the switch. (Its hardness factor of 65-70): two; good sealing performance; due to seal valve seal is the use of artificial grinding until the spool and seal completely consistent to use. So he sealing performance is reliable. Three; light switch; the bottom seal valve seals and seal with the valve spring so tightly together, so when outside forces switch over spring preload very light. Four; long life: the departments have been widely used in petroleum, chemical, power generation, paper, nuclear, aviation, rockets, as well as people's daily life. Compact valve structure, reliable sealing, simple structure, easy maintenance, and spherical sealing surface often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas work in general media, mainly for cut off or connected line of medium, can also be used for regulation and control, pneumatic valve and other valve types of fluids, compared with a rotary output torque, turned quickly, stable and reliable, widely used, such as the following advantages. 1, the stem thrust bearing friction torque is reduced, long-term operation can smooth flexible stem. 2, anti-static function: Set between spring ball, stem, body, static electricity generated by the switching process can be exported. 3, due to Teflon and other materials have good self-lubricating, and friction loss of the sphere is small, so long life pneumatic valve. 4, fluid resistance: a pneumatic valve is the smallest of all valve categories fluid resistance, even reduced diameter pneumatic valve, the fluid resistance is quite small. 5, valve stem seals and reliable: As the stem only for rotational movement imitation without doing the lifting movement, easy to damage the stem packing and sealing ability increased with increasing pressure medium. 6, the valve seat sealing performance is good: use seals made of elastic material such as PTFE, the structure is easy to seal, and pneumatic ball valve sealing capability with the increase of the pressure of the medium increases. Advantages: 1. Fluid resistance, full bore valve basically no flow resistance. 2. Simple structure, small size and light weight. 3. Compact and reliable. It has two sealing surfaces, and valve sealing surface material widely used in a variety of plastics, sealing, and can be completely sealed. In the vacuum system has also been widely used. 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. 5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient. 6. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface. 7. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied. 8. Because there are wiping ball in opening and closing process, it can be used for media with suspended solid particles. Processing of high-precision, high cost, high temperature is not easy to use, as there are impurities in the pipe, easily clogging impurities, causing the valve to open.
