PRODUCT FAMILIES

Which valve family should buyers shortlist?

Compare ball valve support and seats or gate valve body and stem options for isolation duty. Review butterfly valve mounting and geometry or globe valve flow and sealing options when the specified duty includes shutoff or regulation, and check valve closing mechanisms for non-return duty. KEHUA's family pages separate construction choices; the offered model's operating envelope, installation details and acceptance requirements must still match the project.

01INDUSTRIAL VALVE

Ball Valves

For isolation, compare floating or trunnion support separately from soft or metal seats and body-access requirements.

NPS ½–48 · Class 150–2500

02INDUSTRIAL VALVE

Butterfly Valves

Compare wafer, lug or flanged mounting; review offset geometry, seats and the specified shutoff or regulating duty separately.

Wafer / Lug / Flanged · Metal or soft seated

03INDUSTRIAL VALVE

Gate Valves

For full-open isolation, compare body and bonnet construction, then check stem travel, installation space and service conditions.

API 600 / API 6D · NPS ½–48 · Class 150–2500

04INDUSTRIAL VALVE

Globe Valves

Specify shutoff or regulation duty; review body pattern, trim and stem sealing with model-specific flow data where required.

API 623 / ASME · Carbon, low-alloy & stainless steel

05INDUSTRIAL VALVE

Check Valves

For non-return duty, compare the closing mechanism against flow range, installation orientation and reversal conditions.

API 594 / API 6D · Carbon, alloy & stainless steel

06INDUSTRIAL VALVE

Plug Valves

Lubricated, sleeve-type and multi-way plug valve designs

API 599 / API 6D · Class 150–2500

REQUEST FOR QUOTATION

What should you send an industrial valve manufacturer for a quotation?

Send each line item's medium, size, operating and design pressure and temperature, materials, ends, actuation and quantity. Add destination, requested date and document requirements. Use the line-item RFQ checklist and qualification and document review to identify acceptance criteria and unresolved items. Leave unknown values open for technical confirmation rather than treating them as approved specifications.
