  • Types of Check Valves & Their Recommended Applications

    Types of Check Valves and Their Recommended Applications. Check valves are one of the most important valves for any system, whether for industrial equipment or a household item. They’re critical for ensuring the proper operation and to prevent reverse flow and damage. However, types of check valves are designed for a specific application.

  • Check valve Wikipedia

    A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of

  • Check Valves: Wafer Combination Swing Check Valves | Bray

    Compare the Bray/Rite to typical full-sized swing check valves-- Due in part to their oversized, heavier discs, these valves only fully open at an average flow rate of 11 ft/s. When activated at a lower flow rate, these valves loose true controllability and do not fully open. A partially open disc creates an obstruction that produces a higher pressure drop and fluttering of the valve disc
