NEOTECHA NXR PFA LINED BALL VALVES

Transcription

1 These PFA lined ball valves are used in a wide variety of applications in many industries FEATURES GENERAL APPLICATION The valves are ideally suited for corrosive applications, requiring reliable performance, tight shutoff, constant torque and no maintenance. The valves successfully handle a multitude of corrosive applications in industries such as chemical, petro-chemical, pharmaceutical, pulp and paper, foundries and mining like chloric acid, etc. This unique design, together with the self adjusting stem seal (Patent pending) are two of the reasons behind the excellent performance and broad industry acceptance of this valve. TECHNICAL DATA Size range: DN (NPS ½ - ) Temperature ( C): -0 up to +200 Pressure range: vacuum 0.1 mbar to 1 bar (see diagram) Flange connections: DIN PN 1 ASME 150 JIS B K Face to face: DIN EN 55, row 1 ASME B 1.10 PFA lining offers highest corrosion resistance Bubble tight shut-off: precision machined ball and seats guarantees an absolute leak-free valve. Full bore acc. EN 193/EN17292 offers high K v -value equal to the pipe. One-piece ball/stem: no possibility of damaging PFA-lining on ball by the stem, no hysteresis, ideal for flow control applications. Specific anti blow-out shaft design, which can not be affected by the media, according API 09. Static electricity: build-up of static electricity is eliminated since the ball/stem and the housing are of the same potential. Constant torque: the unique two-piece body construction together with the spring loaded seats guarantee a constant torque even after months of operation. ISO15-1 approved. The self adjusting packing is maintenance free and provides a leak free stem seal. The handlever features a positive locked position in the open and closed position. The body has a thermally applied polyester powder coating (RAL 9002) which offers excellent protection against external corrosion and rust.

2 FEATURES One piece ball - stem design with body split out of the spindle sealing. 2. A set of Belleville disc springs exert uniform loading on the packing, resulting in a maintenance free operation. 3. Flexible and corrosion resistant TFM packing ensures a leak-free stem seal (ISO15-1 approved).. Full bore design * resulting in high K v -value, especially required when high viscosity liquids have to be controlled. 5. The PFA lining is min 3.0 mm thick and is spark tested at volts. This ensures a homogeneous PFA lining, void of any pinholes, giving protection against diffusion and corrosion.. The liner is locked to the casting by means of machined dovetails in the casting, permitting the valve to be used on high vacuum and elevated temperature without the danger of a liner collapse. 7. The one-piece mounted ball/stem ensures the best control of the ball without damaging any PFA lining.. The continuous energized spindle seal (using belleville washers) allows the seal is to expand at elevated temperatures, and shrink when cooling down. This maintenance free solution avoids the requirement of packing compression bolts. 9. Locked in energized seats ensure both up stream and down stream bubble tight sealing, constant and low operating torque, and extended service life. 10. Body and adapter part made from ductile iron having a metal to metal contact to insure a perfect sealing of the two bodies. The bodies are coated on the outside with a coating which offers excellent corrosion protection. 11. Full proof anti blow-out shaft design, located in the dry area of the valve and therefore unaffected by the media. * Excluded sizes are ANSI NPS 2, 3,,, these sizes are built in reduced bore design 2
