General valve features:

• DIN / ANSI dimensions

• DIN or ANSI materials

• PN 40 max rating

• Wafer or lugged body styles

• DN 50- 900 mm

• DIN K1 or K2 or API 609 face-to-face dimensions

• Neck length minimum according “Heizungs Anlagen Verordnung”

• Double eccentric disc design with RTFE or metal seat

Design: Body

• Integrated ISO top flange according to ISO 5211

• Open construction which allows easy stuffing box access and adjustments

• Extended neck allowing installation in insulated pipe lines (heating, cooling)

• Face to face according 3202 K1, optional K2, DIN EN 558-1, series 20/25 or MSS SP 67

Design: Body

• External end travel stop

• Integrated in the top flange:

• No obstruction to the media

• No build of solids on the travel stop

• Actuator doesn’t require adjustable end travel stops

Design: Body continued

• Uninterrupted seat retaining ring which
  allows the use of metal spiral wound gaskets
  and
  enables easy maintenance

• Wafer bodies have 4 locating lugs providing
  Easy valve installation
  and
  Correct valve positioning

Design: Disc to stem connection

NOT : Cylindrical and conical as

this offers small shear areas and therefore high material stresses, but is however cheap to manufacturer

Design: Disc to stem connection

By means of Radial pins

• 100% Tolerance free thus no flutter
  and
  Larger shear areas, thus lower material stresses and longer service life

Design: Stuffing box

• Easy accessible

• Easy maintenance due to gland bridge which is allowed to swivel

• Easy gland follower removal by means of pre-machined grove

Design: Axial disc positioning

• Axial bearing is shrunk on the valve shaft

Design: Radial shaft positioning

 

• 2 Bearings on the bottom shaft

• 2 bearings on the top shaft

• Bearings are carbon or stainless steel, PTFE lined (Glacier DU type)

So: Excellent disc positioning
and bi-directional tightness

Design: Seat construction

• RTFE seat

• Fire Safe seat (F/S)
   

Design: Seat construction

• Metal seat (Pulp & Paper version aimed at the paper industry):
  
  Leakage rate : ISO 5208, Rate D
  Maximum : 10 bar
  Sizes : DN 50- 400
  Maximum : 300°C
   

Valve performance

Pressure / Temperature

Valve performance parameters:

• PN 10 : DN 50- 400 for Metal seat (P&P version).

• PN 25 : DN 50- 700 for PTFE & Fire Safe Design

• PN 25 : DN 50- 400 for Metal seat (HT version)

• PN 40 : DN 50-150 with RTFE seat

• Maximum temperature : 300 Degrees Celsius metal seat (P&P version).

• Maximum temperature : 400 Degrees Celsius Metal seat (HT version)

• Maximum temperature : 260 Degrees Celsius RTFE & Fire Safe seat

• All lugged valves are unidirectional end of line. Lugged valves can only be mounted with the seat upstream.

Approvals and certificates:

• DIN 50.049.3.1.B foundry certificates on body and disc

• In compliance with TRB 801

• Fire Safe according API 607, BS 6755-2

• DNV approved for Marine Industry

• Lloyd’s registerer of shipping
