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.

Bellow Seal Gate Valves
Bellow seal gate valves replace the stem packing as the primary seal with a welded metal bellow between bonnet and stem; the bellow stretches and compresses wit

Pressure Seal Gate Valves
Pressure seal gate valves use a bonnet seal that internal pressure itself tightens: above roughly Class 900 the push of the line media forces the pressure-seal

Forged Steel Gate Valves
Forged steel gate valves are the compact small-bore isolation valve of process piping: forging gives a denser grain structure than casting at DN50 and below, wh

Knife Gate Valves
Knife gate valves cut through pulp, slurry, chip and other media that would jam a wedge gate: a thin blade-style disc with a sharpened edge drops through the me

Rising Stem Gate Valves
Rising stem gate valves lift the stem visibly as the wedge travels, so the open/closed position reads from outside the valve — the standard choice where above-g

Non-Rising Stem Gate Valves
Non-rising stem gate valves rotate the stem in place so the wedge travels along the stem thread without the stem rising — the compact choice for buried service,

Wedge Gate Valves
Wedge gate valves close on a tapered solid or flexible wedge that wedges against the seat rings, so sealing force grows with hand torque — the general-purpose i

Parallel Slide Gate Valves
Parallel slide gate valves seal positionally: a spring presses two parallel closure members together for low-pressure seating, then rising line pressure pushes

Through Conduit Slab Gate Valves
Through conduit slab gate valves slide a single flat gate that, when open, leaves a smooth full bore — minimizing pressure drop and keeping slurries and solids

Expanding Gate Valves
Expanding gate valves seal mechanically: the gate assembly expands outward against both seats on closure, giving a bi-directional torque-based seal independent
