产品描述

The Neotecha NeoSeal is a PTFE lined bare stem butterfly valve according ISO 5752/5 short (EN 558-1/T5) with various corrosion resistant disc materials. These valves are ideally suited for corrosive applications, requiring reliable performance, tight shutoff, constant torque and no maintenance.

特点

The elastomer back-up pads behind the liner ensure a tight fit around the disc, for a bubble tight shut-off.
The liner provides a wide flange sealing surface.
A one piece thin disc stem lined with 3 mm molded PFA providing high Kv values.
The liner and disc are the only two valve parts in contact with the medium.
Primary shaft sealing by preloaded contact between disc and liner hub.
Secondary shaft seal by oversizing the shaft diameter in relation to the shaft hole in the liner.
The liner and disc are molded and machined to close tolerances to provide:
- low torque
- less stress and deformation during opening and closing
Vacuum tests with helium with pressures less than 20 Pa absolute (0.2 mbarA).
Optional TFM lining available for extremely demanding applications.
Integral body locating holes to ensure perfect centering of the valve.
Actuator flange and stem dimensions acc. ISO 5211.
