By resistance to influence of ambient air temperature and humidity, the gate valves correspond to NF, climatic category - 3, according to GOST 15150.
The gate valve bears a marking:
on the front side of the body, in cast metal - working pressure, working temperature, nominal diameter, material of body parts;
on the reverse side of the body, in cast metal - trademark of the manufacturer, year of manufacture, frame for gluing a self-destructive plate containing the factory serial number and the Euro-Asian conformity sign.
When released from production, all products are subject to 100% final inspection and assigned an individual serial number.
