Swing check valve 18 inch delivered to USA

Jonloo has delivered swing check valves to a client in USA. These valves are made in A351 CF8 material, which is anti-corrosive.

The customer had quite high demands upon these valves and SGS (the third party) was sent to inspect before delivery. The inspection included the measure of dimensions, the identification of chemical components by spectrograph and pressure test. The results satisfied the requirements, all materials were qualified and all valves showed zero leakage.
