Detail view of Relief Valve
Relief Valves are designed to control pressure in a system, most often in fluid or compressed air systems. These valves open in proportion to the increase in system pressure.
This means they don’t fly all the way open when the system is slightly overpressure. Instead, they open gradually, allowing the system to return to the preset pressure level. When that level is reached, the valve shuts again.
A relief valve works by providing an excessively pressurized fluid an open path to tank with the goal of reducing work port pressure.
As fluid pressure begins to rise, force from that pressure is applied to the bottom of the spool or poppet, similar to what occurs to the piston of a cylinder.
The relief valve opens modestly at first, bleeding as little fluid is as required to maintain pressure as is required downstream. If downstream pressure continues to rise, so too does the force upon the poppet or spool, pushing it further against the spring until the point spring force is equaled by hydraulic force.
The sight glass is a device used between any kind of non-transparent pipeline to observe the flow of liquid. This can be used both in horizontal as well as a vertical pipeline. The sight glass is constructed in such a way that it gives a complete view from every angle. We are the leading manufacturers and suppliers of Relief Valve from Faridabad, India.
