The stainless steel swing check valve utilizes an internal rocker-arm swing mechanism, with the valve's opening/closing component housed entirely within the valve body without penetration, eliminating any potential for external leakage.
This valve is designed for pipelines with nominal pressures (PN) ranging from 1.0 MPa to 42.0 MPa and nominal diameters (DN) from 15 mm to 1200 mm, serving to prevent medium backflow.
