Ordering & documentation
Documents
Ask for the documentation set with the inquiry — typical items (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
Send the medium, temperature, pressure, size and connection for a quotation-ready inquiry. Lead time, MOQ and price are confirmed at quotation, together with the documents to be supplied with the order.
Sample & supply
Supply terms, order quantities and lead time are agreed per order — state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, and keep end-face protectors on until installation; storage limits and shipping arrangements for the selected materials are confirmed at quotation.

Floating Ball Valves
Floating ball valves close on a simple principle: line pressure pushes the bored ball against the downstream seat, so tight shutoff comes without trunnion hardw

Trunnion Mounted Ball Valves
Trunnion-mounted ball valves carry the ball on fixed upper and lower trunnions, so line pressure cannot push the seat and operating torque stays controlled as s

Fully Welded Ball Valves
Fully welded ball valves join the body halves by weld instead of bolted flanges, removing the body joints that leak or need re-tightening on buried, district-he

Top Entry Ball Valves
Top-entry ball valves are serviced through the top cover, so seats, seals and the ball can be inspected or replaced with the valve left in the line — the mainte

Jacketed Ball Valves
Jacketed ball valves wrap the body in a steam or thermal-oil jacket so wax, asphalt, sulfur, polymer and other media that solidify on cooling stay fluid through

Double Block and Bleed Ball Valves
Double block and bleed ball valves give two seating surfaces and a bleed port between them, so a single valve can isolate downstream and upstream pressure and v

Two-Piece Ball Valves
Two-piece ball valves swing a bored ball between open and closed inside a body split into a pressure-bearing main casing and a trim-carrying end piece — the bol

Three-Piece Ball Valves
Three-piece ball valves hold the ball and seats in a center section clamped between two end caps, so the whole trim lifts out for service without cutting the va

Wafer Ball Valves
Wafer ball valves clamp the short-cased body between pipeline flanges instead of carrying their own flanges, cutting face-to-face length, weight and cost on gen

V-Notch Segment Ball Valves
V-notch segment ball valves rotate a segmented ball with a shaped V notch through 90°, so the notch edge shears against the seat while the ball turns — good con
