Description

PFA-lined flanged ball valve made of stainless steel
Two-piece body.
DN 15 – DN 50 : PN10/40

Face-to-face dimension EN 558-1, line 28 (DIN 3202 F1)

Due to the material combination of stainless steel (external) and PFA Fluorpolymere as media-touching lining, very good chemical resistance is achieved all-roand and external corrosive impacts are taken into account.

The interface acc. to DIN 3337 allows safe and economic automation due to direct assembly of actuators.    

 

Approvals

           

  • Meets the requirements of the pressure equipment directive PED 97/23/EC
  • Material certificate EN 10204
  • DIN material according to AD regulations
  • Production monitored by TÜV WO/TRD 100
  • GOST-R certificate for the Russian Federation

Product advantages

Reliable chemical resistance
The massive PFA-lining offfers reliable protection against corrosion of the components in contact with the medium.
The body is also corrosion-resistant to the outside since it is made of stainless steel.

Reliable stem sealing
due to resilient V-rings made of PTFE

High switching frequency
guaranteed by special primary seal design

Full bore
The full opening cross-section and smooth transition areas result in maximum flow coefficients.

Minimum contamination
thanks to optimized/reduced clearance
Anti-blowout proof stem inserted from the inside, completely PFA-lined

Tight shut-off
Leak-tight sealing due to the seats being prestressed to the ball
This design guarantees tight shut-off not only for the whole pressure range but also at lowest pressure.

Cost optimized automation
Actuators can be mounted quickly, safely and economically due to the interface acc. to DIN 3337.
