Why Gate Valve?

Gate Valves or "Block Valves" are the most commonly used valve type in the oil & gas industry.  Gate valves are intended for on-off flow control.  When fully open, fluid flows through the valve in a straight line, resulting in minimum pressure drop across the valve. 

Closure is accomplished by moving the gate across the flow, through the valve body, into the seat area to shut of flow. Warren Valve offers both a flexible, and solid wedge gate design.  The more common, flexible wedge, is a machined disc, designed to mate with tapered integral seats in the valve body.  When the valve is closed, the disc wedges between the two seat rings to establish a tight shut-off.  Rugged construction allows for closure even with dirty fluids mixed with solids.
