Teflon Kaplı Vanalar ve Numune Alma Vanaları
Teflon kaplı vanalar ve numune alma sistemleri genel olarak korozif akışkan uygulamalarında kullanılmaktadırlar. Özellikle kimya, petrokimya, kağıt ve madencilik uygulamarında HCl, HNO3, H2SO4, NaOH, HF gibi agresif akışkanların aç-kapa, oransal kontrol yada tek yönlü akışa müsade edilmesi gibi taleplerde ön plana çıkan teflon kaplı vanalar ve numune alma sistemleri birçok farklı standarda üretilmektedirler. Özellikle DIN & ANSI normunda üretilen teflon kaplı vanalarda birbirinden farklı birçok kaplama malzemesi de kullanılmaktadırlar. PED 97/23/EG Appendix III, Module H'ye göre imal edilen teflon kaplı vanalarımız birkaç farklı ve özel özelliği uhdesinde barındırmaktadırlar.
Örneğin:
* Gövde malzemesi: Minimum Döküm Çelik
* İç Aksam: Minimum 1.4462 duplex üzerine teflon kaplama
* Tek parçalı disk ve milö
* Geri dönüşümden imal edilmeyen teflon granül ki böylece mikro çatlak mümkün olmamaktadır
* 30.000 Voltluk spark test
Long-lasting coating materials of the highest quality, such as PFA, PFA-AS (anti-static), PVDF or ETFE are used for the lining of the bodies and ball encapsulations. One-piece ball-stem assemblies made of solid SS316L, Titanium Gr. 2, Hastelloy C are available as well as ceramic balls with interlocked SS stems. Standard configuration balls offer a full-port cylindrical passage of media. V-Port balls for control applications, Cs configuration and vented balls are also available. The notched stem with the rated breaking point outside the valve is an important additional safety feature for environmental protection.
Leak free requirements over the whole pressure and temperature range of 1mbar to 16 bar resp. -40°C to +200°C (0.01 psi to 232psi / -40°F to +392°F) per EN 12266-1 and API 598 are made possible by the metal-to-metal joint of the 2 body halves, and the maintenance-free dynamically-loaded stem, in accordance with TA Luft (VDI 2440 and DIN EN ISO 15848-1). The choice of body linings and ball encapsulations impact the referenced pressure and temperature ranges. Factory spare parts are easily replaced in the field
Highly corrosive media, hot liquids, steam, toxic gases, etc. in demanding process applications severely test the longevity, quality, functionality and safety of our valves. Kontrol Vanası Sliding Gate Kontrol Vanası Eckardt Pozisyoner, TEFLON KAPLI VANALAR

They are unique process valves that have proven themselves in the most demanding chemical and petrochemical applications, as well in such diverse areas as pharmaceutical, pulp and paper, mining, and related industries.
Numune Alma Vanaları
SSB / SIV / SSV
Swissfluid SIV Inline Sampling Valves are installed directly in the pipeline or in a bypass piping system. Collecting a liquid sample with our cavity-free design results in a representative sample taken directly from the media flowing through the pipeline.
Sampling is carried out without interrupting the process under pressure or vacuum. The samplers can optionally be installed horizontally or vertically.

SSP / SST
Sight Glasses are ideally suited for continuous monitoring of corrosive, abrasive, or toxic process media, in liquid or gaseous state. These substances could be of caustic, explosive or poisonous nature or even constitute a fire hazard.

SBP
They are used in such diverse industries as chemical, petrochemical, pharmaceutical, pulp and paper, mining, and associated fields.
Teflon Kaplı Dİyafram Vanalar
SDV
Its cavity-free and self-draining design make our SDV Diaphragm Valve the preferred choice for chemical and pharmaceutical applications.
Teflon Kaplı Çek Vanalar
SBC / SSC
Due to the solid PTFE ball residing in a high-volume chamber, pressure losses are minimal. The flexible sealing lips at the ball seat area enable positive shut-off with very low pressure differentials. Conversely, the ball allows media to flow freely during the entire opening operation.
