What Gate Valves suppliers provide

Suppliers in this category cover gate valves built for fully open or fully closed shut-off duty, using a sliding gate or wedge that lifts clear of the flow path when open, giving minimal pressure loss. The range includes resilient-seated and metal-seated designs, rising and non-rising stem types, in materials from cast iron and ductile iron to bronze and stainless steel. Core competence lies in matching pressure rating, connection type, and materials to the pipeline medium and application, whether that is drinking water, wastewater, or industrial process fluid. Many suppliers also offer actuation, extension spindles for buried installation, and maintenance parts. Unlike butterfly valves, which use a rotating disc and suit throttling as well as shut-off in a more compact, lighter design, gate valves are generally chosen for larger sizes and applications where a fully unobstructed bore is required. In the pre-selection phase, compare pressure classes and connection standards each supplier covers.

Relevant standards

Gate valves are commonly built to EN 1171 (cast iron gate valves) or EN 1074 (valves for water supply), with flange connections to EN 1092. Testing follows EN 12266 or API 598, and fire-safe designs may reference API 607.

Frequently asked questions

When should I choose a gate valve over a butterfly valve?
Gate valves suit applications needing a fully unobstructed bore and infrequent on/off operation, particularly in larger pipe sizes, while butterfly valves are more compact, lighter, and better suited to frequent operation or throttling.
