For over six decades, L&T Valves has earned a stellar reputation at major refineries and petrochemical complexes across the globe. From the world's largest refinery, where over 500,000 L&T valves are in service, to critical installations on every continent, industry leaders trust L&T Valves to keep their operations running safely and efficiently.

A check valve is basically a one-way swing-type valve and bolted-cover construction, in which the flow can run freely one way, but if the flow turns, the valve will close to protect the piping, other valves, pumps etc. If the flow turns and no check valve is installed, water hammer can occur.

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve

A Globe valve is traditionally used to control the flow of product through a pipeline. This control is achieved through a conical plug and fixed orifice. The conical plug varies the size of the fixed orifice and either reduces or allows more flow. There are a variety of plug and orifice configurations that influence flow rates as required.
