Butterfly Valves

Inquip supply a comprehensive range of butterfly valves, designed to meet ISO standards.

Butterfly Valves are the ideal solution for the interception of gravity-fed or pneumatically conveyed dry powders or granules in a variety of bulk solids handling and processing plants.

Product Range

  • Butterfly Valves VW
  • Fit-Frame Butterfly Valves VFP-VFPX
  • Butterfly Valves VFS
  • Silo Closure Butterfly Valves VFF

Butterfly Valves VW

VW Butterfly Valves consist of a single block body manufactured from die-cast aluminium, a carbon steel or stainless steel disc including shafts, and an elastomer seal. An adjusting lever or pneumatic or electric actuator can be applied to the valve. The three WAM-type actuators are perfectly interchangeable. Interchangeability of the drive shaft (standard: DIN 5482; option: ISO 5211) and universal connection to different size flanges results in variety of configurations.

  • Differential pressure: max. 2.5 bar (36.3 PSI)
  • Operating pressure: max. 2.5 bar (36.3 PSI)

Fit-Frame Butterfly Valves

VFP Butterfly Valves consist of two high-pressure die-cast semi-bodies manufactured from aluminium alloy, a swivel disc in SINT engineering polymer, stainless steel or cast iron, and a pre-stressed elastomeric
seal.
For food applications a version with stainless steel disc and integral FDA-approved seal is available.
VFP Butterfly Valve can be used for any kind of powder or granular material stored in silos or containers.

Benefits of Fit-Frame Butterfly Valves VFP-VFPX

  • Certified EC 1935/2004
  • Quick maintenance thanks to the small number of components
  • Lightweight and easy to handle thanks to minimized height dimensions
  • Easy to fit thanks PN and ANSI flange compatibility
  • Low residue and contamination thanks to the new inlet dimensions and sizes available
  • Ex-stock delivery

Butterfly Valves VFS

VFS Butterfly Valves consist of two high-pressure aluminium alloy die-cast semi-bodies, a SINT polymer composite or cast iron swivel disc, and a pre-stressed elastomer seal.
For the food industry a version with stainless steel disc and an FDA/EN-approved, integral seal is available.
While V1FS has a top flange and beaded bottom section – suitable for the attachment of a flexible sleeve – V2FS comes with identical top and bottom flange.

Benefits of Butterfly Valves VFS

  • Highly abrasion-resistant
  • Easy to fit
  • Time-saving maintenance
  • Low operating and maintenance costs
  • Interchangeable discs
  • Ex-stock delivery

Silo Closure Butterfly Valves VFF

VFF-type Silo Closure Butterfly Valves are manufactured from a one-piece fabricated carbon steel body lined with SINT engineering polymer composite. Due to the four corner slots the integrated upper square flange can be adapted to different sizes of silo outlet flanges. The valve disc is manufactured from surface-treated carbon steel.

Benefits of Silo Closure Butterfly Valves VFF

  • Special dust-tight seal geometry
  • Abrasion-resistant
  • Easy-to-fit
  • Ex-stock delivery
