⚠️ The Real Cost of Cheap Lug Valves

❓ Frequently Asked Questions

Everything You Need to Know About Lug Type Butterfly Valves

What is the difference between a lug type and a wafer type butterfly valve?

A lug type valve has threaded inserts (lugs) on both flanges, allowing it to be installed with bolts and nuts. It can be used for dead-end service — meaning you can remove the downstream pipe without depressurizing the system. Wafer valves slide between flanges and cannot support dead-end service. For maintenance flexibility, lug type is the preferred choice.

Can you supply lug butterfly valves with pneumatic or electric actuators?

Yes, absolutely. We offer complete actuated valve packages — pneumatic (double acting / spring return) or electric (on/off, modulating, with positioner). Actuator bracket and coupling are ISO 5211 compliant. Tell us your control signal (4-20mA, 24V DC, etc.) and we’ll match it.

What certifications do your lug valves comply with?

All standard valves are ISO 9001, CE-PED, and RoHS certified. We also offer models with UL, WRAS, KTW, NACE MR0175, and FDA compliant linings. A full certification pack (material certificate, test report, declaration of conformity) is included with every shipment.

What is the typical lead time & shipping cost?

Standard stock sizes (DN50–DN300) ship in 7–15 working days. Larger sizes or custom orders take 20–30 days. Shipping cost depends on quantity and destination — we use FOB Tianjin / CIF to major ports. Request a quote for precise freight calculation.

Do you offer free samples or small trial orders?

Yes. We encourage pre-production samples for qualification. Generally, we provide 2–3 free samples for standard sizes (buyer covers shipping). After confirmation, we move to mass production with consistent quality.

What payment terms do you accept?

We accept T/T, L/C, Visa/Mastercard (via secure link), and for established customers, net 30/60 terms. Minimum order quantity is low — even 10 pieces for standard sizes.
