Diaphragm Valves for handling solid or powder

  
 

Catalogue#: 090351799

  
     
  Iris Diaphragm Valves (IDV's) are used in all bulk materials process industries, due to their high degree of material flow control, coupled with rugged design. Valves are available to suit a wide range of applications; from heavy-duty open discharge and in-line process systems to light duty valve operations on portable bins.

There are six types of IDV making up the Iris range: AD, BD, C, E, H & K. Nine bore sizes are available (not all available for each type), with a compliment of eleven diaphragm materials to suit almost any flow control application in the dry bulk solids industry.

Further information on the principles of the Iris Diaphragm Valve can be found here

Series AD
 The most popular valve in Iris' hand operated IDV range, the AD Valve offers many standard features :-
  • Double Diaphragm for in-line applications requiring no leakage to atmosphere.
  • Robust construction for medium to heavy duties of upto 1600 kg/m³ loading.
  • In-situ diaphragm adjustment reducing maintenance time.
  • Proven design suitable for frequent operation. Bore sizes from 80 mm to 450 mm.
  • Diaphragms selected to suit application.
Construction. Body parts are manufactured from aluminium, zinc and bronze alloys. Plastic triggers and 316 stainless steel screws all combat corrosion. ø450 model available with handwheel operation only.

Options include: -

  • 316 Part or Full construction.
  • Multi-notching to enhance flow control.
  • Coated standard construction.
  • Handwheel operation for sizes 150 mm to 380 mm.
  • TELEFLEX remote hand operation on sizes 100 mm to 300 mm (Standard aluminium construction only)

Series BD
 These valves offer a simplified construction compared to other in-line IDV's reducing cost, size and weight. Features include:-
  • Double diaphragm for in-line applications with no leakage to atmosphere.
  • Suitable for lighter duty, upto 560 kg/m³.
  • Simple design, suitable for applications requiring infrequent operation.
  • Bore sizes from 50 mm to 300 mm.
  • Diaphragms selected to suit application.
  • Standard available with thumbscrew locking for 50 mm to 80 mm bores, giving infinite flow control.
  • Trigger locking mechanism on other sizes.
Construction. Body parts are manufactured from aluminium, zinc and bronze alloys. Plastic triggers and 316 stainless steel fasteners help combat corrosion. Options include: -
  • Thumbscrew locking on all trigger operated valves.
  • A variety of coatings are available for corrosive environments

SERIES C

|| Series AD || Series BD || Series C || Series E || Series H || Series KD ||Back to the top

Series C
 The Series C Valve has been specifically designed to allow diaphragm removal without removal of the valve body from situ, dramatically reducing 'down time' when servicing and allows the use of different diaphragms for each batch, preventing cross contamination. Other benefits include: -
  • Single diaphragm, reducing spares costs.
  • Internally mounted felt seals prevent product leakage making the valve suitable for in-line applications.
  • Robust construction and diaphragm clamping make the valve suitable for medium duties upto 1120 kg/m³.
  • In-situ diaphragm adjustment.
  • Suitable for frequent operation.
  • Bore sizes ranging from 100 mm to 300 mm.
  • Diaphragms selected to suit application.
Construction. Body parts are manufactured from aluminium, zinc and bronze alloys. Plastic triggers and 316 stainless steel fasteners help combat corrosion. Options available: -
  • 316 stainless steel construction.
  • Nylon or PTFE seals.
  • A variety of surface coatings for corrosive applications.
  • TELEFLEX remote hand operation on all sizes with standard construction.
SERIES E || Series AD || Series BD || Series C || Series E || Series H || Series KD ||Back to the top
Series E
 The Series E Iris Diaphragm Valves have been the work-horses of the Iris powered valves for many years. Their extremely robust construction and reliable drive elements make them suitable for the most arduous duties. Standard Features:-
  • Double diaphragm for in-line applications requiring no leakage to atmosphere.
  • Strong construction making E Valves suitable for duties over 1600 kg/m³.
  • Electrical or pneumatic operation to suit available power supplies.
  • In-situ diaphragm adjustment.
  • Internal bearings and high quality materials make the E Valve suitable for frequent operation.
  • Bore sizes from 150 mm to 460 mm.
  • Diaphragm selected to suit application.
Construction. Body parts are manufactured from aluminium, zinc and bronze alloys. Plastic triggers and 316 stainless steel fasteners help combat corrosion. Options Available: -
  • 316 stainless steel contact parts.
  • Fully open, closed and intermediate electric or pneumatic limit switches.
  • Automatic closure system in case of air or electrical failure on pneumatic valves.
  • Special packages to suit hazardous locations.
  • A variety of surface coatings to suit corrosive environments.
SERIES H || Series AD || Series BD || Series C || Series E || Series H || Series KD ||Back to the top
Series H
 The Series H Valves have been designed specifically for use with Intermediate Bulk Containers (IBC's). This low cost, compact valve has been fitted to many thousands of IBC's the world over. It's popularity with operators owes to it's ease of operation, reliability and excellent regulation of discharge rates. Standard Features: -
  • Single diaphragm for dust tight closure.
  • Simple construction specifically designed for IBC'S, upto 720kg/m³.
  • In-situ diaphragm adjustment.
  • Bore sizes from 100 mm to 300 mm.
  • Hand operated, suitable for infrequent use.
  • Diaphragms to suit application.
Construction. Aluminium alloy, clear anodised for protection against environmental conditions. Trigger and bearings are moulded from Acetal plastic. Options Include: -
  • Coated standard construction.
  • Additional notches for enhanced flow regulation.
  • Quick release transit cover for extra security during transportation.
  • Quick release adapter for valve mounting

SERIES KD
