Model NTB/NTC Ball Valve
Brand: Emerson Electric Co.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 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. TA-Luft VDI 2440 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 for type NTB, and 6 intermediate positions for type NTC.
- The body has a thermally applied polyester powder coating (RAL 9002) which offers excellent protection against external corrosion and rust.
- Direct mounting according to ISO 5211.
