NTB/NTC PFA Lined ball valve

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.
