1、 Specifications and brief description
Specification: NPS 2-30 (DN 50-750), Class 150-900 (PN 16-150)
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.
main features
① Hinge built-in rotary design reduces valve body leakage points
② The sealing surfaces of the valve disc and valve seat are hard welded, with good wear resistance, high temperature resistance, corrosion resistance, and scratch resistance
③ Sensitive action and good low-pressure sealing performance
④ The valve disc closes quickly and the water hammer pressure is low
⑤ Long service life and reliable performance
