Gate Valve 3d model

A Sluice Valve, also known as a Gate Valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. This movement allows for unobstructed flow and minimal friction loss when fully open. All texture files are 2048 in greatest dimension, ensuring high-quality visual representation. The distinctive feature of a Sluice Valve is the planar sealing surfaces between the gate and seats. The gate faces can form a wedge shape or remain parallel. While some Gate Valves are designed for regulating flow, many are not suited for this purpose, having been engineered to be fully opened or closed. When fully open, the typical Sluice Valve has no obstruction in the flow path, resulting in very low friction loss. Gate valves are characterized as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position, while nonrising stems are used where vertical space is limited or underground. Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning, also giving the body added strength. Bolted bonnet is used for larger valves and higher pressure applications. Another type of bonnet construction in a Sluice Valve is pressure seal bonnet. This construction is adopted for valves for high-pressure service, typically in excess of 15 MPa (2250 psi). The unique feature about the pressure seal bonnet is that the body-bonnet joint seals improve as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint. Gate valves normally have flanged ends which are drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels.
