YASH make offers check valve, which are ideal to reduce flow resistance and pressure drop to the minimum possible level. They are perfectly engineered, lapped and screwed in seat to ensure tight shut-off and long life. ACheck valveis a mechanical device that normally allows fluid (liquid or gas) to flow through it in only one direction & the other for fluid to leave. Its a two-port valves.
Function of Check Valve is to prevent the reverse flow of fluid/gas/air in case of failure or sudden brake-down occurs in Piping Systems. There are various types ofcheck valvesused in a wide variety of applications.Check valvesare often part of common household items. Although they are available in a wide range of sizes and costs, many check valves are very small, simple, and/or cheap. The bodies (external shells) of mostcheck valvesare made of plastic or metal.
CHECK VALVES ARE AVAILALE IN SINGLE / DUAL PLATE DESIGN/WAFER/SWING TYPES.

"YASHmakeSwing Check/Non-Return Valvesare designed and manufactured according toBS1868/ API/BS/DIN STANDARD. Check Valves as popularly known in the Piping System in all fields are considered very critical in its application.Valvesare provided with properly guided Swing Disc through a Hinge for High Temperature and Pressure, Soft Sealing for Pneumatic and Vacuum applications. The design ensures the Valves function smoothly with a very nominal differential pressure from either side. The disc is designed so compact and light weight to ensure minimum pressure drop across the Valve.
Available in varied materials like Cast Iron, Cast Carbon Steel, Cast Stainless Steel of all Grades, High Alloy Steels, Hastelloy etc. Manufacturing range commences in size from 50NB through 600NB; in Pressure Rating from ANSI 125# through 1500#.
We offer a range of precision check valves that are designed to be self cleaning, quick opening, and positive sealing. These can be customized on the basis of clients specifications. Therefore, they are available in various dimensions and designs. They are mainly used to make liquid or gas flow in only one direction. These check valves used in a wide variety of applications in many industries

"YASHmake Bleed valves are designed for use on products such as multi-valve manifolds, or gauge/root valves. Functionally, the valve vents line pressure either to atmosphere or to containment when used with optional barbed vent tube. Bleed valves are used whenever an instrument is removed from a system or to assist in the calibration of control devices.
Bleed Valves are also calledDouble Block & Bleed valvegenerally, as this valve is made up by two ball valve and one needle valve or twoball valveand aglobe valve.
Double Block and Bleed valveshave evolved to replace and add the process of bolting together individualvalvesto make the valves in one body. it saved a lot of space and material, it is the development tendency of the valve in the future. These new assembly of thedouble block & bleed valveprovides great savings in weight, space and installation times especially in cage isolation. Double Block and Bleed valves have evolved to replace the process of bolting together individual valves to provide dual isolation. This new assembly provides great savings in weight, space and installation times especially in instrument & can be seen in the reduction of leak paths to atmosphere
