Кто должен настраивать давление срабатывания?

Настройку и пломбировку предохранительного клапана должен выполнять аттестованный специалист в соответствии с проектным давлением защищаемой системы — самовольная перенастройка запрещена нормами промышленной безопасности.

Нужна ли поверка предохранительных клапанов?

Да, предохранительные клапаны подлежат периодическому техническому освидетельствованию согласно требованиям Ростехнадзора — обычно раз в год, точный интервал зависит от типа установки.

Frequently asked questions

FAQ

How does a full-lift valve differ from a low-lift one?

The full—lift opens completely when the setting pressure is slightly exceeded, providing maximum relief - it is used on steam and gas. The low lift opens in proportion to the excess pressure — it is more often used for liquids.

Who should adjust the actuation pressure?

The safety valve must be adjusted and sealed by a certified specialist in accordance with the design pressure of the protected system — unauthorized reconfiguration is prohibited by industrial safety standards.

Do I need to check the safety valves?

Yes, safety valves are subject to periodic technical inspection according to Rostechnadzor requirements — usually once a year, the exact interval depends on the type of installation.

We will select and install safety valves according to your parameters (model, DN, PN, material) with all the documents — a passport and a certificate of conformity.

Send a questionnaire or an enquiry and we will promptly prepare an offer with prices and lead times.
