A gate valve gets its name from your internal mechanism so that the flow of water. This mechanism seems as if a tiny gate that moves around on a stem, and that is connected to the handle. The handle is often a screw handle that moves the gate around, frequent lowering and raising the valve when necessary here . They are best utilised in on/off applications the spot that the valve can be used infrequently. They are sometimes present in home plumbing systems, though ball valves have grown to be more popular in this subject. They are also commonly seen in the oil and coal industry, pharmaceuticals, manufacturing, automotive, and marine applications. They can be found in high pressure and high temperature environments, so may be often within manufacturing.

The most typical housing materials for ball valves are brass, stainless-steel and PVC. The ball is normally made of chrome plated steel, chrome plated brass, metal or PVC. The seats are often crafted from Teflon, but may also be manufactured from other artificial materials or metals. More information on this topic you could find on the page: Chemical resistance of materials.

Brass ball valves hold the largest business. Brass can be an alloy of copper and zinc and contains good mechanical properties. Brass valves can be used for (drinking) water, gas, oil, air and several other media. Chloride solutions (e.g. seawater) or demineralized water could cause dezincification. Dezincification is really a form of corrosion where which zinc is removed from your alloy. This makes a porous structure that has a greatly decreased mechanical strength.

Trunnion ball valves produce an additional mechanical anchoring in the ball at the summit and bottom. They use a splined or keyed stem connection that eliminates any play between ball and stem. V-port ball valves possess a ‘V’ shaped ball instead from the standard round hole. This allows for additional control because from the tapered opening, allowing to get more linear flow.
