Gate valves

Sort:

A gate valve is a type of pipe fitting with a locking element in the form of a flat plate. The plate made of stainless steel or cast iron is capable of cutting inclusions in the flow, which contributes to the expansion of the scope of application of gate type fittings. The standard knife gate valve is capable not only of completely blocking the flow, but also of regulating its power by reducing/increasing the through hole. The device creates minimal resistance to residual liquid (gas), which ensures a high level of tightness.

The design and principle of operation of gate valves

The affordable cost of gate valves is due to their simple design. A moving locking element is located inside the cast iron or stainless steel housing. Under the influence of force, the gate is activated and completely or partially blocks the flow. The surface of the gate is a sharpened guillotine (knife), which is easily cut by inclusions in the stream. Additionally, the knife gate valve is equipped with a connection: flanged or with an internal thread. Pipe fittings of this type are made of corrosion-resistant materials with a wide range of operating temperatures.

Criteria for the selection of gate valves

The catalog includes devices from European manufacturers: CMO (Austria), END and Festo (Germany), Zetkama (Poland). When choosing, you need to take into account the main technical characteristics:

  • diameter (DN) from 50 to 700 mm;
  • pressure (PH) from 3 to 16 bar;
  • housing material;
  • the type of connection.

The fittings are certified, supplied to the consumer with accompanying documentation and a manufacturer's warranty.

Scope of application of gate valves

Gate valves are used to block the flow of "dirty" liquids: fecal and household effluents, pulp liquids, oil and gas waste, discharges from pulp and paper mills and other production facilities. The devices are used in vacuum technology when a high level of tightness in pipelines is required.
