This Check Valve is widely appreciated owing to its top-notch quality, sturdy construction and supreme functionality. It is a disc-based valve that allows the uninterrupted flow of fluids in open position, and completely blocks the flow when it is closed. To meet the variegated demands for the product, we have manufactured it in a variety of disc and seat designs. Apart from this, Check Valve can be availed from us in the budget-friendly price range.
UTVC make Cast Carbon Steel and Stainless Steel or Alloy steel swing type Check valve Bolted Cover BS 1868 A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid 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 applications. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. An important concept in check valves is the cracking pressure, which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
