Steel wedge gate valves shut off liquid and gaseous media in pipelines. Selection takes account of nominal size DN, nominal pressure PN, body material, closure design, end connections and actuation.
The source catalogue describes full-bore and reduced-bore valves, rising and non-rising stems, and parallel and wedge closure designs. Wedge designs include solid-wedge and double-disc versions; a flexible solid cast wedge is specified as the catalogue default.
Technical values have been checked against the supplied Ufa Neftemash catalogue. They remain reference information rather than a confirmed current specification. Confirm every DN/PN combination, material, connection, applicable standard and available version against current manufacturer documentation before ordering.
The product table is an availability matrix: each pressure is not necessarily available for every size. Unlisted DN and PN values require manufacturer confirmation. PN 320–400 kgf/cm² requires additional agreement. The source catalogue mentions manufacture to API 6D upon customer request; applicability must be confirmed for the selected product.
Specify DN, PN, medium, temperature, steel grade or required material, end connections, face-to-face dimension and actuator type. For gaseous, flammable, explosive or toxic media, the source catalogue requires the designation “газ” (gas).
Product passports, technical documentation and price lists are available on request.
