Product Description

API 6A oilfield Pressure Seal Check ValveCheck Valves are installed in high pressure lines to stop reverse flow by the automatic close of flapper or dart. Flapper check valves include top-entry check valves and in-line flapper check valves, which allow fluids to flow towards the wellbore and prevent flowing backwards. For dart check valves, the flow will open the dart by overcoming the small spring force. When the flow runs in opposite direction, the spring will push the dart against the seat retainer to prevent reverse flow. We provides both standard and reverse-flow check valves. And we have also developed check valves for sour service in accordance with NACE MR0175.
