Brand Innovation Model Q41F-16P Stainless steel flange connection form in the form of fixed ball valve structure of various nominal diameter DN15-DN300 (mm) Medium highly corrosive chemical media pressure environment Pressure Operating temperature Room temperature Standard GB Flow direction Unidirectional Drive Manual parts and accessories hand wheel uses flow control type (channel position) straight-acting compact object water specifications DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250 valve structure, sealing reliable, 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 pipe the way the media can also be compared with the regulation and control, pneumatic valve and other types of valves for fluid, 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 for the rotation of the stem just do not do 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 the ball valve sealing ability with increasing pressure of the medium increases. [Product advantages: 1, fluid resistance, full bore ball basically no flow resistance. 2, simple structure, small size and light weight. 3, close 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. 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, in the 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, a 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, due to the opening and closing of the valve wiping process, it can be used for media with suspended solid particles. 9, 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.
