Description: CP 6D pipeline swing check valve

2、 Detailed information

Product Overview

The swing check valve adopts an internal hinge swing structure, and the opening and closing parts open or close by themselves based on medium flow and force. Featuring good sealing performance, low pressure sealing, low linear vibration, and low pressure drop, it is suitable for media such as water, steam, and oil. It is mainly used in pipelines such as petroleum, chemical, and natural gas, effectively preventing media backflow.

Design and inspection can comply with standards such as API 6D, GB/T 12236, BS 1868, API 598, GB/T 26480, etc. Fire safety design meets API 6FA requirements, and NACE anti-corrosion and acid resistance are optional.
