3 Inch Gate Valve
Description of 3 Inch Gate Valve: ZECO 3 inch gate valve is mainly used for fully open or fully closed switching valves. They are usually not used for throttling purposes, but for slurries, viscous fluids, etc. Gate valves feature a removable wedge that moves with the stem nut. The wedge moves perpendicular to the direction of flow. Gate valves usually have a minimum pressure drop when fully ...

Sanitary Gate Valve Main Structural Features and Functions
Sanitary gate valve's main duty is to cut off. When it is fully open the entire pipe gets straight through. At this time the pressure loss of medium operation reaches minimum. Its main advantage is the small fluid flow resistance. It is usually not required to frequently open and close or to keep the gate fully open or fully closed. It is not suitable for regulation, throttling use. If used for ...

Industrial Gate Valves
Industrial valves are devices that are used to regulate liquids, gases, and slurries. The flow of liquids or gases can be controlled using these valves. This can be done through pipes and other passageways by opening, closing, and partially obstructing the passageway or pipe. Different types of Industrial Valves include: • Gate Valves • Globe Valves • Ball Valves • ...

8` SlurryFlo Control Valve - Case Study
We then introduced a SlurryFlo control valve into the 3D model, with identical piping layout, downstream knife gate valve and flow parameters (see Fig 2). A side-by-side comparison of the two flow models depicts very different scenarios; SlurryFlo’s patented trim design acts as variable orifice, centering the abrasive froth slurry within the ...

8` V-port Ball Valve - Case Study
The client had installed several v-port ball valves to modulate the flow of diluted froth slurry. Upon 4-5 months in service, the ball valves were severely eroded and the piping required rotation (or replacement). Isolation knife gate valves were also installed downstream to provide tight shut-off, however they too were damaged by the ...

East hull pumping station case study
Client: Yorkshire Water CSG provided two 1200mm Hydraulic Cylinder Gate Valves as part of the East Hull Pump Station overhaul. CSG worked in partnership with Pacific Valves Ltd on the £16m flood prevention project commissioned by Yorkshire Water. Due to the low ground levels in and around Hull flooding can often be an issue. The new pumping stations will help control drainage in the area ...

A comparison between different techniques for water network sectorization
Water network partitioning represents one of the best methodologies for improving water balance and pressure control of a water distribution system in order to reduce water leakage. These techniques can be applied with greater effectiveness defining a smaller permanent network district, called a District Meter Area (DMA), achieved by the insertion of gate valves and flow meters. If the DMAs are ...

Learining how to Choose Materials for Gas Valves
The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...

South Texas Landfill − Case Study
During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an ...

Why Does Serious Injury and Fatality Prevention Require a Different Approach?
For some years, safety leaders have seen a troubling disparity between significant decreases in overall injury rates and relatively flat fatality rates. A study conducted in 2011 helps show why: traditional safety efforts often fail to reduce serious injuries and fatalities (SIFs) because they just weren't designed to. SIF events usually have different causes and correlates than less serious ...
