A translation issue regarding a valve
Thread Content
Hello, experts. A beginner is here to ask for advice again. The foreigner described the valve as follows: BALL VALVE 18” (450MM) SPLIT BODY, METALSEALING, FULL BORE, CONSTRUCTION TYPE A. The valve body includes an exhaust plug. Valve body material: ASTM A105. Seat material: A182-F316 with a STEELITE overlay. Ball material: A182-F316 with a chromium carbide coating. Is my translation correct? But there are still some issues I don’t understand, so I came here specifically to ask for help. A split body means a two-piece valve body, right? What does that \"construction A\" mean? What criteria determine Class A structures? The material of the valve seat and the valve core is already specified as F316; why are there then two additional words indicating other materials? Should overlay be understood as a sealing surface? I would be extremely grateful if my questions could be answered!
1 I understand it to be like this. 2 I don’t understand; waiting for an expert to explain. 3 The valve stem is made of 316 material, with a Stellite coating on its surface
Thank you to the sofa owner for their reply; I’m wondering if any experts can explain what construction A is
Sealing test: Class A leakage rate, equipped with a vent valve, that is, an exhaust and drain valve
Overlay should refer to surface welding. I’m waiting for experts to explain what construction A means; I guess it has something to do with the structural length of the valve: lol
Thank you to the people who replied above. Also, hello to the expert on floor 4. Do you mean that Construction A refers to a leakage level of A? "Does “BODYCOMPLETE WITH VENTAND PLUG” mean it comes with a vent valve? I translated it as ‘with an exhaust plug’: ’(It’s a purely literal English translation with no professional tone. . . Waiting for a reply from the 4th floor.

An exhaust valve is located at the upper part of the valve body, while a drain valve is located at the lower part. The main function of the exhaust valve is to prevent overpressure in the valve chamber, serving as a protection mechanism for venting. The drain valve is used for draining waste and cleaning. “\"Construction A\" – I was just thinking that maybe it’s part of the same sentence as what follows, \"BODY COMPLETE WITH VENTAND PLUG\" Additionally, I’d like to remind you that your first question is best translated in a separate clause. Because split-type also comes in two-piece and three-piece versions. A direct translation of “two-piece” is inaccurate.
Thank you to the expert above for clarifying this. I also once imagined that Construction A was part of a single sentence connected to the subsequent body.
