Gate valve vs. ball valve: which one should you use?

How much more a flanged ball valve costs and weighs than a gate valve, when both fit the same gap and how hard a fast-closing ball valve hits a long line. Calculated with list prices, a market sample and manufacturer data sheets from DN 15 to DN 300 (½″ to 12″).

Which valve fits your line?

Work through the questions from top to bottom. The first one that applies decides.

1. 1Size larger than DN 100 (4″)?→ Gate valve or butterfly valve
2. 2Must the valve close within seconds, e.g. emergency shut-off or gas?→ Ball valve
3. 3Line longer than about 100 m (330 ft) or velocity above 1.5 m/s (5 ft/s)?→ Gate valve, or ball valve with gearbox
4. 4Solids or fibres in the medium?→ Resilient-seated gate valve or knife gate valve
5. 5Is the valve rarely operated and could it seize, e.g. a main shut-off?→ Ball valve
6. 6Must the position be visible from a distance?→ Ball valve

How ball valves and gate valves work

EN 736-1 lists the ball/plug valve and the gate valve as two different basic valve types ¹. In a ball valve the closure member turns about an axis across the flow, and the flow passes through it. In a gate valve the closure member moves in a straight line, across the flow ¹¹.

In practice: you open and close the ball valve with 90°. A resilient-wedge gate valve takes 14.5 turns to open at DN 50, 21.5 at DN 80 and DN 100, 32 at DN 150 and 34 at DN 200, according to the data sheet (VAG EKO plus type 201) ⁷. On the ball valve the lever shows the position; on the gate valve you only see it with a rising stem.

US standards by title: MSS SP-110 “Ball Valves Threaded, Socket-Welding, Solder Joint, Grooved and Flared Ends”; API 600 “Steel Gate Valves – Flanged and Butt-welding Ends, Bolted Bonnets”; API 602 “Gate, Globe, and Check Valves for Sizes DN 100 (NPS 4) and Smaller …”; MSS SP-70 for cast iron gate valves and MSS SP-80 for bronze gate, globe and check valves ¹³.

Mini study: price, weight and length by size

From which size is the gate valve cheaper, and does a ball valve fit the gap of a gate valve? We first looked at one distributor that sells both types in the same pressure rating, then across many sellers as a cross-check.

The distributor series in numbers

* At DN 100 the distributor only lists the long pattern (series 1). The short series 27 would have the same length as the gate valve per manufacturer data sheet: KLINGER Ballostar KHE-FK DN 100 with 190 mm and 31.6 kg ^{7, 8}. Net list prices, weights and lengths per distributor and data sheet, 2026-11-02 ².

Cross-check: many sellers instead of one series

A single distributor can be an outlier. So we asked the same question on Google Shopping in Germany and the US: flanged, hand-operated, cast or steel body, one value per seller, counted from three sellers ⁶. The direction holds: with flanges the ball valve costs more, and the gap grows with size. In the market it is smaller than in the distributor series, though. At 2″, where US ball valves are mostly threaded brass, the ball valve is even slightly cheaper.

German prices as displayed, mostly incl. VAT; US prices excl. sales tax. Materials and pressure ratings mixed within a group; DN 50 ball valve only 6 sellers. The factor 6.1 at DN 200 comes from the distributor series only. Retrieved 2026-11-02 ⁶.

What does this mean for you? Up to DN 100 you can usually replace a series 14 gate valve (formerly F4) one-for-one with a short-pattern flanged ball valve (series 27), paying about 1.4 times as much at DN 50 in the market. With size the ball valve gets much more expensive – 2.7 times at DN 100 in the market, 6 times at DN 200 in one distributor’s range –, longer from DN 125 and almost twice as heavy from DN 150. There, the butterfly valve is the alternative to the gate valve; the numbers are in our comparison ball valve vs. butterfly valve.

Pressure drop: both are almost loss-free when open

Fully open, neither valve slows the water much. We calculated the ball valve’s ζ value from the Kv value in the data sheets ^{5, 7}. It ranges from 0.12 at DN 15 to 0.04 at DN 200. At DN 100 and 80 m³/h (about 350 gpm, 2.8 m/s) that is roughly 2 mbar (0.03 psi). US data sheets give Cv instead: Cv = 1.156 · Kv.

Manufacturer data sheets, own analysis, 2026-11-02 ⁷. Only one manufacturer states a ζ value for the gate valve (VAG EKO plus); other data sheets give none. 2.83 m/s ≈ 9.3 ft/s.

What does this mean for you? Fully open, both are practically loss-free. The difference is not pressure drop but price, length, operating time and behaviour when closing.

Water hammer: quarter turn vs handwheel

Both valves shut off tightly. The difference is how fast they do it – and that decides the water hammer. Our example line: steel pipe DN 50 (60.3 × 2.9 mm), 100 m (330 ft) long, water at 20 °C flowing at 2 m/s (6.5 ft/s), closed completely ³. The pressure wave travels at about 1,355 m/s in this pipe; KSB gives 1,000 to 1,400 m/s for steel pipes ⁴. There and back it needs 2 · 100 m ÷ 1,355 m/s ≈ 0.15 s.

The effective closing times are our calculation assumption, not a measurement and not a data sheet value. By lever the ball valve is closed in about 1 s; only the last 20 % or so actually cut off the flow, so ≈ 0.2 s (range 0.1–0.3 s). The DN 50 gate valve needs 14.5 turns ⁷. At about one turn per second and again 20 % effective stroke, that is 14.5 s × 0.2 = 2.9 s (range 2–5 s).

If the valve closes more slowly than the wave needs there and back (here more than 0.15 s), Michaud’s approximation applies ⁴:

Steel pipe DN 50 (2″), water at 2 m/s (6.5 ft/s). Effective closing times assumed; “slow” means about 5 s of lever travel, 1 s of it effective. Approximations without friction or valve characteristic. Real values are lower if the pump keeps running or air pockets are in the line ^{3, 4}.

What does this mean for you? In short domestic lines a briskly closed ball valve is no problem. In long lines from about 100 m and at 2 m/s it produces pressures above PN 16, about 14 times as much as the gate valve. Close ball valves slowly there, fit a gearbox – or use a gate valve.

Can you change a gate valve to a ball valve?

With flanges up to DN 100, usually yes. What matters is the face-to-face length: per manufacturer data sheets, the short ball valve series 27 matches gate valve series 14 (formerly F4) up to DN 100, and the long series 15 (formerly F5) from DN 125 ⁸. In our distributor series both are 150 mm long at DN 50 and 180 mm at DN 80. At DN 150, though, the ball valve measures 350 mm and the gate valve 210 mm – it does not fit the gap there ².

Check the pattern: long-pattern ball valves (series 1) are much longer, 350 instead of 190 mm at DN 100 ². The data sheet of the actual valve always decides; what to look for is explained in reading data sheets correctly.

Two more points belong to the swap. The ball valve closes far faster than the gate valve, so in long lines close it slowly or fit a gearbox. And from DN 150 it weighs almost twice as much (72.5 vs 41 kg, 160 vs 90 lb); the pipe supports must carry that ².

Replacing your main shut-off gate valve

At home this is usually a threaded or soldered brass valve between ½″ and 2″. Match the end connection (NPT thread or solder) and choose a full-port ball valve, so the bore is as large as the pipe and the valve loses hardly any pressure ⁷.

Price is rarely an argument here: at 2″ the US median is $66 for a ball valve and $77 for a gate valve ⁶. Water hammer is not a problem in a short house line either: 20 m (66 ft) of pipe at 2 m/s gives about 4 bar (58 psi) even with a fast quarter turn ³.

One more reason for the swap: a valve that sits unused for years can seize. A ball valve with its quarter turn is easier to move; if you keep the gate valve, open and close it now and then.

Ball valve or gate valve? Typical applications
