In fluid piping systems, pressure management is a crucial aspect of ensuring the reliable operation of the entire system. Safety valves and pressure reducing valves may appear similar, as both are valve components designed to manage pressure. Many novice users easily confuse the two, even using them interchangeably. However, they actually address two completely different problems: one serves the daily operation of equipment, while the other handles the risk of sudden failures.

Both screw pumps (single screw) and rotary lobe pumps are positive displacement pumps, primarily used for conveying high-viscosity pastes and shear-sensitive materials. They are self-priming, and their flow-through components can be made of 316L stainless steel, while seals are made of FDA-compliant EPDM or PTFE. Although their applications overlap, their structures differ, resulting in significant differences in conveying performance, maintenance methods, and material compatibility.

Stainless steel flanges are widely used in various industrial sectors, from heavy chemical industry to pharmaceuticals and food processing.

Stainless steel piping systems are widely used in various industrial sectors, from heavy chemical industry to high-purity biopharmaceuticals. However, there is a fundamental gap in cleanliness requirements between "industrial grade" and "hygienic grade," and the logic behind their connection methods is also completely different.

Butterfly valves, as a type of valve with a simple structure and rapid opening and closing, play an important role in industrial pipeline systems. When stainless steel is chosen as the main material of a butterfly valve, its design needs to make fuller use of the corrosion-resistant properties of the material, based on the general butterfly valve structure.

In pure water, ultrapure water, and purified water equipment systems, sanitary pipe fittings are the core transport carriers of the entire water treatment equipment and are widely used in key links such as RO reverse osmosis, EDI ultrapure water, sterile water storage, and circulation transport.

In cleanroom piping systems for food and beverage, pharmaceuticals, biochemicals, and pure water purification, sanitary sight glasses are indispensable observation accessories. They are primarily used for real-time observation of internal media flow, material reactions, and liquid levels within tanks and pipelines, allowing staff to promptly monitor production conditions.

An emulsifying pump is a device used to achieve rapid emulsification and homogenization of liquids, and it is widely used in industries such as food, cosmetics, pharmaceuticals, and fine chemicals. It can transform immiscible materials such as oil and water phases into a stable, homogeneous emulsion system in a short time, making it one of the key pieces of equipment in modern continuous production.

A butterfly valve is a simple, widely used quarter-turn valve. Its name comes from the butterfly-shaped valve plate, which opens or closes the flow path by rotating 90 degrees. The following section details how a butterfly valve works, covering its structure, operating principle, evolution of eccentric design, operation methods, and advantages and disadvantages.

Butterfly valves are commonly used control valves in pipeline systems. Their core opening and closing element is a disc-shaped butterfly plate, and the valve stem rotates from 0° to 90° to achieve pipeline opening and closing and flow regulation.
