PFA lined Ball Valves - Type NTB- and NTC
Gachot Ball Valves Model NTB/NTC - 6278 These PFA lined ball valves are used in a wide variety of applications in many industries.
Features
•PFA lining offers highest corrosionresistance•Bubble tight shut-off: precisionmachining of ball and seats guarantees
an absolute leak-free valve.•Full bore offers high Kv-value equal tothe pipe•Metallic mating body halves: unaffectedperformance (torque and tightness) due
to axial and lateral forces caused by
piping installation.•One-piece ball-stem: no possibility ofdamaging PFA-lining on ball by the stem;
possibility of blow-out is eliminated.•Static electricity: any build-up of staticelectricity on the ball is eliminated sincethe ball stem and the housing are of
same potential.•Constant torque: the unique two-piecebody construction together with the
spring loaded seats guarantee a
constant torque even after months of
operation.•The self adjusting packing needs nomaintenance and guarantees a leak-free
stem seal.•The handlever features a positive lockedposition 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 againstexternal corrosion and rust.
Technical data General application
Size (mm): 15 - 150Temperature (°C): -40 up to +210Pressure range: vacuum 0,1 mbarto 16 bar (see diagram)Flange connections: DIN PN 16, ANSI 150, 300JIS B 2212 10 KFace to face: DIN 3202/T1/F1ANSI B 16.10 The Gachot ball valves are ideally suited forfluid flow applications, requiring assuredperformance, tight shutoff, constant torque
and no maintenance. The valves are
handling successfully a multitude of
corrosive applications in industries, such as
chemical, pharmaceutical, pulp and paper,
foundries and water treatment. 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.
