Overview
1、 YG41H/W Liquid Ammonia Flow Restriction Valve - Features: When the pipeline or accessories are damaged and leak directly to the outside, causing a rapid increase in flow rate and exceeding the set value of the valve, the valve will automatically close under the action of the medium and pressure difference, preventing the accident from further expanding. After the accident is eliminated, the valve will automatically resume operation. Suitable for installation at the inlet and outlet of tank area pipelines or loading and unloading pipelines. 2、 YG41H/W Liquid Ammonia Limiting Valve - Performance Specification: Nominal Pressure PN
