					PFA lined Ball Valves - Type NTB- and NTC

These PFA lined ball valves are used in a wide variety of applications in many industries.

Features
• PFA lining offers highest corrosion resistance • Bubble tight shut-off: precision machined ball and seats guarantees an absolute leak-free valve. • Full bore offers high Kv-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 609. • Static electricity: any build-up of static electricity on the ball is eliminated since the ball/stem and the housing are of same el. potential. • Constant torque: the unique two-piece body construction together with the spring loaded seats guarantee a constant torque even after months of operation. TA-Luft VDI 2440 approved. • The self adjusting packing needs no maintenance and provides a leak-free stem seal. • The handlever features a positive locked position in the open and closed position for type NTB, and 6 intermediate positions for type NTC. • The body is polyester coated (RAL 9002) which offers excellent protection against external corrosion and rust. • Direct mounting according to ISO 5211.

General application
The Neotecha ball valves are ideally suited for fluid flow applications, requiring reliable performance, tight shutoff, constant torque and no maintenance. The valves are handling successfully a multitude of corrosive applications in industries such as chemical, petrochemical, pharmaceutical, pulp and paper, foundries and mining such as sulphuric acid treatment plants. This unique design, together with the self adjusting stem seal (U.S. Patent 4.696.323) are two of the reasons behind the excellent performance and broad industry acceptance of this valve.

Every valve has a mounting flange according to ISO 5211 which simplifies the mounting of any actuator built to this standard. A set of Belleville disc springs exert uniform loading on the packing, resulting in a maintenance free operation. Flexible and corrosion resistant virgin PTFE packing ensures a leak-free stem seal (TA-Luft VDI 2440 approved). Full bore design resulting in high Kv-value, especially required when high viscosity liquids have to be controlled. The PFA lining is 3 mm thick and is spark tested at 30 000 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. The ball/stem with lower trunnion is molded in one piece ensuring uniform support of the ball, keeping the pressure on the seat constant under all operating conditions. Wear and tear on the seats is reduced, resulting in an increased operating life. The C-ball* reduces flow distortion and provides excellent regulating characteristics. An ideal control valve for highly corrosive or sterile products. C-ball stem with trunnion end, all molded in one piece ensures uniform support of the ball, keeping the pressure on the seat constant under all operating conditions, reducing wear and tear on the seat, which results in an increased operating life. Available in DIN and ANSI face to face dimensions, which allow an easy replacement of plug- and diaphragm valves. Energized ball seats are responsible for a constant operating torque over the entire service life of the valve and result in a bubble-tight seal.

Rugged symmetrical body halves made from ductile iron (GGG 40.3), coated on the outside with polyester paint, offer excellent corrosion protection. 11. The split body design allows the ‘dead spot’ between ball stem and housing to be kept to an absolute minimum. The C-ball version is dead-spot free. 11a. The C-ball valve is dead spot free and is ideally suited to shut-off and control poisonous, solidifying or high purity products where it is imperative that no product is entrapped in the ball and the surrounding cavity. 12. Full proof anti blow-out shaft design, located in the dry area of the valve and therefore unaffected by the media. * C-Ball® is a registered trademark

The C-ball lined valve is dead spot free and is ideally suited for shut-off and control of corrosive, poisonous, crystallizing or high purity products where it is imperative that no product is entrapped in the ball and surrounding cavity. The C-ball valve is based on a full port design resulting in high Kv values, especially required when high viscosity liquids have to be controlled or for those applications which require a large rangeability. The advantage of the C-ball is a reduced flow distortion and excellent control characteristic. The optimization of the control valve performance is achieved with a customer characterized seat or the linear characterized V port seats which are available for 15, 20, 30, 40, 60 and 90°.
