Flanged Pinch Valves
The flanged pinch valve is the mechanically-clamped, flanged-body execution of the pinch valve family: a rubber sleeve is the only wetted part, compressed by an external mechanism to close on the flowing medium. The benchmark execution covers DN25 to DN600 at PN10/16 with cast iron or ductile iron bodies, a wide seal-sleeve list (NBR, EPDM, VITON, PTFE-bonded ductile iron, WCB, CF8, CF8M) and stainless stem options, across a -20 to 300 C window depending on sleeve choice.

Application & selection guidance
Select this execution for abrasive, scaling or corrosion-prone water, oil and gas lines where the medium should only touch rubber - slurries, effluent and sludge service included - in DN25 to DN600 PN10/16 pipework. Pick the sleeve (NBR for oil resistance, EPDM for water and waste water, VITON for hot aggressive media, PTFE-bonded where chemical inertness dominates) against the medium, then confirm the -20 to 300 C window at the chosen sleeve and the DIN 2501/2532/2533 flange drilling.
Frequently asked questions
Why does a pinch valve suit abrasive and scaling media?
The rubber flow channel is the only part the medium touches. Its smooth wall resists scaling - each open and close cycle crushes accumulated scale off - and the full-bore opening leaves no cavities or turbulence when open, so abrasive slurry does not erode seats the way it would in a gate or butterfly valve.
How is the sleeve material chosen for this execution?
The source execution lists NBR, EPDM, VITON, PTFE plus ductile iron, WCB, CF8 and CF8M options. EPDM covers water and waste water, NBR covers oils, VITON extends to hotter aggressive media, and the PTFE-bonded sleeve serves where chemical inertness dominates - each with its own temperature ceiling inside the -20 to 300 C overall window.
What information is needed to quote a flanged pinch valve?
Nominal size within DN25 to DN600, PN10 or PN16 class, medium confirmation (water, oil or gas), the sleeve material against that medium and its temperature within -20 to 300 C, stem material (SS416, SS304 or SS316), and the DIN 2501/2532/2533 flange drilling.
Ordering & documentation
Documents
Ask for the documentation set you need with the inquiry β typical items for this execution (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
A quotation-ready inquiry states: nominal size and pressure rating, body and seat material preference, end connection, operation, and the service medium with temperature. Typical values on this page are benchmark reference ranges; the binding values are confirmed at quotation.
Sample & supply
Supply terms, order quantities and lead time are agreed per order β state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, keep end-face protectors on until installation, and for elastomer- or PTFE-seated executions avoid prolonged outdoor storage β seat compounds age fastest in direct sunlight and freezing conditions.
