A parallel slide gate valve is a kind of valve. It is designed to transmit flow through a piping system. Unlike other gate valves, this type is easy to install and requires little space along the pipe axis. This valve is used in the chemical industry, petroleum industry, and natural gas industry. Usually, these valves are forged, but they can also be cast. They are made of hardened metals and are suitable for both on-and-off fluid flow applications. These valves have high durability and are very simple to clean. However, they need to be opened and closed carefully. Because of the nature of the sealing mechanism, it is important to make sure that the seat is seated properly. If the seat deforms, the pressure from the fluid may cause a leak. Are Parallel Slide Gate Valves Easy to Operate? Parallel slide gate valves are very easy to operate. They can be operated by handwheel, pneumatic actuators, or electric motors. Using the handwheel, the operator applies torque to the stem. As a result, the valve’s operating characteristics are similar to other gate valves. This is because the valve operates with low energy, which makes the pumping process more efficient. There are many advantages of using a parallel slide gate valve. One of the most significant is its ability to seal over an entire surface. Another advantage is its ability to be made fire safe. How Does a Parallel Slide Gate Valve Work? Parallel slide gate valves are used to control the flow of liquids in piping systems. They provide isolation of a piping system and are commonly used in chemical and power generation industries. The valves can be driven by pneumatic or electric motors. Their compact design makes them suitable for use in pipelines. The valve is designed to maintain its seal under both high and low-pressure conditions. It is also suitable for service under very high temperatures. An anti-static design is also provided. A flexible graphite gasket is also used for a fire-safe design. The springs on the valve keep the upstream and downstream seating in sliding contact. This reduces operating torque. When the pressure is relieved, the valve seat automatically resets. In this way, sealing is achieved over the entire surface. Where Are Parallel Slide Gate Valves Used?

Applications of Strainers in Industry Strainers are used industrially for filtering liquids like water, oil, and sand. Additionally, they remove rust, leaves, and other organic debris from the flow stream. When processing materials, different mesh sizes are employed to capture particles of 40 microns or greater. 60-mesh strainers typically capture particles at 240 microns, while 100-mesh strainers can handle particles as small as 150 microns or greater. When selecting a strainer, material sensitivity to flow is an important consideration. This can be determined by pipeline velocity, differential pressure drop, and open area ratio. Pipeline Velocity – This refers to the speed of liquid through a system, measured in gallons per minute (GPM). Accurate measurement of this flow rate is essential in selecting an appropriate strainer size and determining what differential pressure can be experienced without damaging the basket. Viscosity (Viscosity) – Viscosity is the sensitivity of a fluid to flow, and it’s essential to understand how viscosity varies based on temperature and the material being filtered. Dirt Loading (DL) – This refers to the weight percentage of particulate contaminants in a pumped liquid or slurry form that must be removed for moisture removal. It’s essential that this liquid be correctly pumped in order to avoid filter clogging and subsequent system malfunction. How To Select A Pipeline Strainer? A pipeline strainer is an advanced filter that separates contaminants and particulates from the liquid. Not only does this improve efficiency in a process, but it can reduce maintenance costs, too, since particles won’t damage downstream equipment. When selecting a strainer for your pipeline, there are several factors to take into account. One of these is the size of the hole and mesh, which determines how many particles can be captured by the strainer. In general, strainers should have holes slightly smaller than the particles you want to filter. This ensures any foreign debris is captured before reaching downstream equipment and helps protect your investment. When selecting a basket filtering element, there are a few essential things to take into account. Strainers' materials used can significantly affect how well the element will hold up under high pressure. When selecting a pipeline basket strainer, the open area ratio (OAR) should be taken into account. This quantity determines how long a strainer can be used without cleaning or losing pressure across its basket or screen. In most cases, the OAR is calculated by analyzing the relationship between an internal cross-section area of a basket or screen and its overall open area. A wider opening allows more time for the basket or screen to work without needing cleaning, which may cause pressure loss. Differentiating Filters and Strainers When it comes to particulates that need removal, the size of the particles can determine which strainer or filter is appropriate. If they are larger than 40 microns in diameter, a strainer would be an optimal option; if smaller, then filtering would be the better solution. Selecting the correct mesh for a strainer or filter is critical in determining its effectiveness and how often it must be cleaned. If particulates being removed are extremely fine, a finer mesh may be needed; however, this would also necessitate more frequent cleaning sessions. Another critical distinction between a strainer and a filter is the pressure of gas or liquid that passes through them. With a strainer, there is no noticeable drop in pressure as the substance passes through. Conversely, substances passing through a filter will typically experience an abrupt decrease in pressure regardless of whether they need to be cleaned or not. This is essential because lower pressure enhances filtration efficiency and minimizes the possibility that debris will escape from the system.
