Sourcing FAQ

How do I confirm a Chinese supplier actually manufactures pinch valves (not just resells sleeves)?
Ask for factory photos, production capacity (monthly output), an OEM statement, or an official product page on the supplier's domain showing valve models and manufacturing details; several Chinese firms explicitly state they are 'manufacturers' on their product pages.
What typical minimum order quantities (MOQs) should I expect?
MOQs vary by supplier and whether you order whole valves or replacement sleeves; many manufacturers will accept small sample or trial orders but require higher MOQs for custom sizes—confirm with the factory when requesting a quote.
What certifications or tests matter for pinch valves with EPDM sleeves?
Request material certificates for the rubber (batch/compound data), valve body material certificates, and functional pressure/vacuum testing records; ask about ISO quality management if you need factory‑level assurance.
What drives lead time for EPDM sleeve pinch valves?
Lead time depends on actuation type, sleeve manufacturing (custom reinforcement or compound), order quantity, and whether parts are in stock; custom‑sized sleeves or large orders typically add production time.
