Class 150, 300
➤ We offer a complete range of gate valves manufactured in accordance with API Std. 600
and tested to API Std. 598.
➤ Rating in accordance with ANSI B 16.34
➤ Gate valves are straight-through flow valves which provide positive shutoff with minimal pressure drop
and flow turbulence.
➤ The barrier to flow is a wedge sliding at right angles to the direction of flow.
➤ Gate valves may be installed without consideration for the direction of the flow.
➤ They are not recommended for use in a partially open, throttling position as erosion, noise and
excessive wear can occur. Gate valve installations should always be made with consideration for the
potential of bonnet over-pressurization caused by fluids which may become entrapped in the bonnet
of a closed valve.
➤ Where this possibility exists, it is the user’s responsibility to insure that proper venting is installed.
