EXPERT make Forged Gate Valves are used when the need exist for a device that allows an interruption or cut off the flow of a fluid. Gate Valves are not to be used for flow modulation. The valve should remain either fully open or fully closed. Installation of a Gate Valve is independent of the flow direction.
The Globe Valves are primarily used to modulate or regulate the volume of the flow.A Globe Valve is not recommended when a continuous full flow of fluid is required due to the high pressure drop inherent to the design of a Globe Valve. This type of valve should always be installed such that flow intake enters through the base of the valve seat.
Check valves are generally used to protect pumps or similar equipment, allowing the flow only in one direction and preventing flow reversal due to back pressure. Metal seated check valves may not provide drop tight sealing when used in gas system or fluid system with low back flow pressure.
