Gate Valves

Unlike a globe valve’s disc, which sits permanently within the flow path — even fully open, the flow must go around the seat and disc geometry — a gate valve’s flat or wedge-shaped gate is raised straight up, via a multi-turn linear stem, completely out of the flow path and into a bonnet cavity above the pipe bore. When fully open, the gate is genuinely withdrawn entirely from the flow, leaving an unobstructed, straight-through bore nearly identical to the pipe’s own diameter — genuinely different from a globe valve, which always retains its seat and disc geometry within the flow path.

This creates a real, distinct advantage over both ball and globe valves specifically for full-bore, minimal-obstruction service. Because the gate is genuinely removed entirely from the bore when fully open — not just rotated aside like a ball valve’s solid portion, and not merely lifted but still present like a globe valve’s disc and seat — a gate valve provides the lowest pressure drop of the three valve types at full open, with a flow path essentially as clear as an unobstructed length of pipe. This is why gate valves are the traditional choice specifically for full-open or full-closed isolation service on large-diameter, high-volume lines, where minimizing permanent flow restriction matters even more than fast or precise actuation.

A genuine, honest limitation follows directly. Because opening or closing requires the gate to travel the entire height of the bore via a multi-turn stem, a gate valve is genuinely the slowest of the three to operate fully. And, like a ball valve, its partially raised gate position creates a highly irregular, unpredictable flow restriction not suited to throttling at all — worse, in fact, because a partially raised gate can experience severe turbulence, vibration, and accelerated wire-drawing erosion damage to the gate and seat surfaces if left in a partially open position for extended periods, a genuine, more severe consequence than either a ball or globe valve experiences from partial-position operation.
