The requirement
The buyer wants an insulated valve near a washdown zone. The handwheel must remain usable and the plant’s cleaning team needs a wipeable exterior.
How the design was approached
Collect the exact cleaning agents and concentrations, cycle temperatures and site zoning. Return a drawing showing the closure direction, overlaps and stem clearance for buyer and hygiene review.
Construction and fit
Compare smooth PTFE-faced fabric and an enclosed core. Agree a downward-facing overlap where practical and size thickness from the actual thermal target, available clearance and approved materials.
Acceptance checks
Review a sample for full handwheel travel, removal for inspection and compatibility with the agreed cleaning procedure.
