Что даёт трёхсоставная конструкция крана?

В трёхсоставном корпусе крайние части (концевые муфты) разбираются отдельно от центрального узла с шаром — это позволяет заменить или подтянуть уплотнения без демонтажа всего крана с трубопровода, что упрощает обслуживание.

До какой температуры можно использовать нержавеющий кран?

Обычно рабочий диапазон − от −20 до +180 °C, но точный предел определяется материалом уплотнения (чаще всего PTFE), а не самой сталью — при повышенных температурах уточняйте параметры конкретной модели.

Frequently asked questions

FAQ

AISI 304 or AISI 316 — which one to choose?

AISI 304 (an analog of the domestic 08Х18Н10) is suitable for most food and general industrial applications. AISI 316 contains molybdenum and is more resistant to chloride corrosion — it is a standard choice for seawater, chemically aggressive media and pharmaceuticals.

What does a three-part crane design do?

In a three—piece housing, the end parts (end couplings) are disassembled separately from the central assembly with the ball - this allows you to replace or tighten the seals without removing the entire crane from the pipeline, which simplifies maintenance.

Up to what temperature can a stainless steel faucet be used?

The operating range is usually -20 to +180 °C, but the exact limit is determined by the sealing material (most often PTFE), and not by the steel itself. At elevated temperatures, specify the parameters of a specific model.

We will select and supply stainless steel ball valves according to your parameters (design, DN, PN, material) with all the documents.
