NAEGELEN^® lined ball valves provide excellent performance due to their outstanding corrosion resistance in various industries especially in the chemical, petrochemical and pharmaceutical industry. For decades lined ball valves have been successfully used in numerous applications thoughout various industries.

• Excellent diffusion and corrosion resistance due to virgin fluorocarbon resins
  The 3 mm thick ball valve liners consist of high-quality virgin FEP, PFA or PVDF. The lining of body, ball and stem guarantees that corrosive media never get in contact with metal valve components.

• Minimal cavities reduce the possibility of product contamination
  The design of NAEGELEN® lined ball valves minimizes the cavity space of the body and prevents retention of process media in the body cavity ensuring therefore the cleanliness of the media and a consistent product quality.

• Full bore design guarantees low pressure drop
  Compared with reduced bore valves, pressure loss is minimized and the flow capacity increased significantly in the full bore design.

• Modular concept of body and shaft sealing
  The different sealing systems are easily interchangeable.

• Long-term protection against external and internal leakage,
  less than 10-6 mbar l/s
  The multi-stage, high performance packing prevents external leakage. The excellent in-line tightness is achieved by the floating ball valve design and high quality components. We have successfully tested our stem packing for more than 200 000 operations.

• Low maintenance costs and long life-time
  The intrinsic valve design and the top quality components guarantee long service life and minimum maintenance costs.

• CIP - as well as GMP and FDA conformity

  PTFE - standard packing Maintenance-free life loaded packing Double packing for exceptional safety requirements

   

• Metal to metal body joint (Type R 201M)
  for controlled lining compression, especially for heavy duty applications with mechanical and thermal loads.

• NAEGELEN^® ball valves with ceramic ball
  for abrasive media and operation under high pressures & temperatures, e.g. in the chemical & pharmaceutical industry.

• Tank bottom valve
  The valve design can be used for discharging of vessels with a minimum of pressure loss.

• Heat jacketed ball valve
  for applications requiring precisely regulated temperatures e.g. for polymerizing media.

• Ball valves with grounding strap
  The grounding strap connects the two body parts to guarantee electrical conductivity.
