API · ASME · DIN · EN standard industrial valves
Industrial valves for isolation, regulation and check service
Ball, gate, globe, check, butterfly and specialty families — catalog specs tied to their governing standards, with a cross-reference for specification and quotation work.
Inside the Hefei factory
One site, end to end: casting and forging come in, CNC machining, assembly and calibration happen on 12 production lines, every valve passes hydrostatic and gas test bays, and finished valves ship from our own export docks.
Why source industrial valves here
Four things a procurement team can verify on the page in front of them — before the first inquiry.
Specs tied to standards
Every family page carries its design and testing standards — API 6D, API 600, ASME B16.34, EN counterparts — so a specification can be checked, not just read.
Collected benchmark data
Size ranges, pressure classes and material options are collected benchmark data from published manufacturer references, with per-field provenance kept internally — never invented.
Full family coverage
16 families and 92 type subtypes — isolation, regulation, check and specialty service — organized as a real catalog tree, three clicks to any page.
Quote-ready pages
Standard, pressure class and size are on every page, so an inquiry can state exactly what procurement needs — no back-and-forth to pin down the duty.
Product families
Each family page carries the type's spec fields, applicable design and testing standards, and selection limits.
Ball Valves
Quarter-turn valves with a rotating ball, fast to operate and tight-closing across isolation and control duties.
Explore Ball Valves →
Gate Valves
Linear-motion isolation valves that lift a gate clear of the bore — full-bore, low-resistance shut-off for lines that stay open or closed.
Explore Gate Valves →
Globe Valves
Linear-motion valves for regulation and throttling, with disc moving perpendicular to the seat.
Explore Globe Valves →
Check Valves
Self-acting valves preventing reverse flow, protecting pumps and piping from surge damage.
Explore Check Valves →
Butterfly Valves
Quarter-turn valves with a rotating disc, compact for large diameters in utility and process isolation.
Explore Butterfly Valves →
Diaphragm Valves
Valves sealing through a flexible diaphragm, built around sealing reliability in corrosive, slurry and utility service.
Explore Diaphragm Valves →
Needle Valves
Instrument-size valves with a needle-shaped stem for precise metering and fine flow adjustment.
Explore Needle Valves →
Plug Valves
Quarter-turn valves with a cylindrical or tapered plug for fast isolation, diverting and dirty-media duty.
