About Gate valve:

A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or rectangular
gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces
between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid
and minimum restriction is desired. The gate faces can be parallel, but are most commonly wedge-shaped.
Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be
used for regulating flow, unless they are specifically designed for that purpose.

Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
For extremely thick fluids,a specialty valve often known as a knife gate valve is used to cut through the
liquid.On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to
percent of opening.This means that flow rate does not change evenly with stem travel. Also, a partially
open gate tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively
high fluid velocitycausing gate and seat wear and eventual leakage if used to regulate flow. Typical gate
valves are designed to be fully opened or closed.When fully open, the typical gate valve has no obstruction
in the flow path, resulting in very low friction loss.

Selection of anti rotation and non anti rotation for electric cylinder telescopic rod

Due to the high transmission efficiency and lack of self-locking characteristics of the ball screw inside the electric cylinder, when the expansion rod nut moves in a straight line inside the electric cylinder barrel, the expansion rod nut will rotate slightly in the direction of the ball screw thread due to inertia and friction. When the internal anti rotation limit of the electric cylinder or the end of the telescopic rod is connected to a non rotating structural component using a U-shaped double ear seat (or thread), the rotational movement of the telescopic rod is restricted, and the electric cylinder telescopic rod can be retracted without rotation. The general application requires anti-rotation restrictions on the piston rod. In some cases, such as front and rear U-shaped fork foot electric cylinders, six degree of freedom platforms, etc., electric cylinders without anti rotation structures are required. The rotation of the telescopic rod will affect the displacement accuracy of the electric cylinder, and it should generally be determined in the early stage of selection whether the electric cylinder requires anti rotation.
