Butterfly Valves

Products: Butterfly Valves

Standard Design

The high performance butterfly valve range is a reliable option for more critical applications and longevity. We have worked with many end user specifications to include their requirements in our standard design. This means that we can manufacture high quality high performance butterfly valves rapidly.

NDT conducted on sample castings per batch to ensure high quality castings for right first time assembly and production.

Our Range

  • Concentric Rubber Lined
  • Double Offset
  • Triple Offset

Full rating on design pressure and bidirectional as standard.


Product design features

  • Increased corrosion allowance to meet end user specifications, where specified
  • Modular seat and seal design, including firesafe
  • Integral top bracket
  • One piece stem
  • Bidirectional for full ASME pressure rating

Production range

  • 2” to 24”
  • 150 and 300lb
  • Manual and Actuated

Material scope

Statoil approved QTR qualified to NORSOK M650 edition IV.

  • Carbon and Low Temperature Carbon Steel
  • Austenitic and Super Austenitic Stainless Steels
  • Duplex and Super Duplex
  • Nickel alloys and Super alloys eg 6Mo, Hastelloy, Inconel and Monel

All from high quality castings. Other material combinations available against specific requirements.

  • Seat options including PTFE, PCTFE, RPTFE, Firesafe, Inconel
  • Seal options including Graphite, PTFE, Chevron, O- Rings
  • Specific paint requirements including NORSOK systems

Features & benefits

  • Design and material changeability has the ability to meet all service conditions designed for offset butterfly valves
  • Integral top bracket which increases accuracy of sealing by removing any play in bolted brackets
  • Bidirectional flow which maintains positive sealing for more critical applications
  • One piece stem which maintains accuracy in disc travel, sealing and torque travel

Design features

Butterfly valves  meet the following standards as a minimum: API 609, ASME B 16.34, ASME B 16.5, 16.10,  API 607, NACE MR 01 75.

Seats

Choice of seats depending on application including metal seated and firesafe seated.

Replaceable in the field ensuring minimum downtime.

Stem Design

Thicker stem designed into valve from outset, creating a higher MAST, this eliminating most actuator safety factor issues associated with butterfly valves.

Stem Sealing Design

Different options with extra  sealing options for those more demanding applications.

Body Design

Built to cater for most customer specifications in terms of corrosion allowance requirements.

Testing

API 598/EN 12266-1
