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…

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,…

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…

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…

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…

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…

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.

What sizes and pressure ratings are available for gate valves?
The published size range is 1/2" to 88" (DN15 to DN2200), depending on model, and the published pressure ratings are PN10 to PN450, Class 150 to Class 2500. Availability of a specific size and rating is confirmed at quotation.
What materials are gate valves available in?
The published specification lists body materials: Cast iron, Ductile iron, WCB, WCC, LCB, LCC, WC6, WC9, CF8, CF8M. Material availability for a specific size and rating is confirmed at quotation.
What working temperature range do gate valves cover?
The published working temperature range is -196°C to 570°C. For a medium at the edge of the range, confirm the suitability of the selected seat and body materials at quotation.
What end connections do gate valves support?
The published specification lists Flanged, Butt-weld, Socket-weld, Threaded, Wafer, Lug as the available end connections. The connection for a specific size is confirmed at quotation.
What should a quotation inquiry for gate valves include?
The governing standard and class, nominal size, body and seat materials, the service medium with temperature, and the destination — anything missing is confirmed during quotation.
