Description

 

 

Two-piece stainless steel flanged ball valve
DN 15 – DN 100 : PN 10/40

DIN 3202 F4 / F5
EN 558-1 line 27/15

DIN 3202 F1
EN 558-1 line 28

Made of stainless steel and prepared for cost optimized automation - direct assembly of control elements and actuators due to interface in compliance with DIN 3337. The body is made of stainless steel precision casting, then externel profile is precisily formed. The sturdy screw attachment of the middle flange absorbs pipe forces safely too.

Breakaway torques refer to ball valves in depressurized condition. They may vary acc. to medium, temperature, pressure and frequency of operation.

** based on water at ambient temperature; seats made of PTFE/Glass

Product advantages

Reliable connection
direct mounting of acctuators due to interface in compliance with DIN 3337. No interruption of stem towards the actuator

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

High switching frequency
guaranteed by special primary seal design

Precise assembly
due to fully centered screw guidance.

Anti-blowout stem
inserted from the inside, surface of ball super-polished and precisely formed.

Reliable tightness
to the outside through fully encapsulated body seal

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.

Firesafe approval and ANTI-STATIC device
are standard for the series.
