Overview

Application:

Pressure and Temperature Limitations: This is a low-pressure valve, typically used in PN10/16 level systems. It cannot be used in high-temperature, high-pressure main steam or fuel oil systems. System parameters must be confirmed to be within the valve's rated range during selection.

Media Compatibility: Although resistant to seawater, it is not suitable for strong acids, strong alkalis, or other special chemicals. When used with oily media, the compatibility of the sealing material must be confirmed.
