For proper installation of the VOG Iran swing check valve, the flow direction must match the arrow marked on the valve body to ensure correct operation of the disc. Flange surfaces must be clean, flat, and free from rust to achieve proper sealing with NBR or EPDM gaskets. Flange bolts should be tightened gradually in a cross-pattern to prevent localized stress and leakage. The valve should be installed horizontally or vertically with upward flow to prevent the weight of the assembly from affecting disc closure. A minimum straight pipe length equal to one pipe diameter before and after the valve is recommended for stable flow conditions. After installation, a hydrostatic pressure test and functional check of disc movement are required to confirm proper sealing and free motion.
