Different from common pipeline valves, special valves are a type of valves with specific functions and uses. They usually play a key role in specific industrial fields or application scenarios to meet special operation and management needs. These valves are designed according to specific use environments and needs and have excellent sealing and switching performance. Generally speaking, special valves either have special design structures or are made of special materials to meet the challenges brought by special occasions and media, ensuring stable operation under extreme conditions.

Ball valves is designed to regulate fluid flow with unparalleled efficiency and reliability. Its core feature is a ball with a hollow hole that rotates 90 degrees to switch between open and closed states, achieving precise regulation and control of the fluid and providing optimal sealing performance. When the hole is aligned with the pipe, the flow is unrestricted; when rotated, the ball blocks the passage, ensuring a tight seal.

Butterfly valve is a simple control valve that realizes fast switching and adjustment operation by rotating the valve disc. It mainly serves to cut off and throttle in pipelines. The core features include compact design, lightweight structure, elastic or metal valve seat seal. It is suitable for low-pressure to medium-pressure systems, providing fast operation, minimum pressure drop and space-saving installation in water, gas or air applications.

Gate valve controls fluid flow by raising and lowering the wedge/disc perpendicular to the flow path. Its core features include parallel or wedge-shaped disc, low flow resistance, and non-throttling design for full open/ full closed operation. It works through a stem-driven gate that opens an unobstructed passage by lifting the wedge and blocks flow by sealing the disc, making it ideal for on-off work in pipelines where minimal pressure drop is required.

Globe valve is a flow control valve that controls the fluid passage through a movable disc connected to the valve stem, which is closed against the valve seat. Its core features include a sphere with a narrow flow channel, high flow resistance and precise throttling ability. It works through linear valve stem movement, opens by lifting the disc to allow fluid to flow, and closes by pressing the disc against the valve seat to regulate flow or pressure. It is widely used in systems that require frequent regulation or tight closure.

Check valve is the valve that has a circular disc as the opening and closing part and blocks the backflow of the medium by its own weight and medium’s pressure. Its core features include a movable closing element (such as disc or piston) and valve seat for tight sealing. It uses the principle of pressure difference to open when the upstream pressure exceeds the downstream pressure, and closes by gravity or spring force to block the backflow, ensure system safety, and prevent equipment damage.

Plug valve is a quarter-turn valve that controls flow by rotating a cylindrical or tapered plug that aligns with the flow passage. Its core features include a sealed plug, quick operation, and resistance to clogging by viscous or granular media. Through the rotational motion, the valve plug is aligned with the valve body to open, allowing the flow to flow unimpeded; and when closed, the valve plug rotates to block the passage. It is well suited for on-off applications in high viscosity systems, and due to its simple design, it provides fast operation and minimal maintenance.

Strainer is an indispensable device on the pipeline that conveys the medium. It can filter out solid particles in the fluid in the pipeline to protect the downstream equipment. Its core functions include a perforated or mesh screen element, a shell to capture debris, and a removable basket for easy cleaning. It works by guiding the fluid through the screen tube, allowing the liquid to pass while retaining pollutants. Commonly used in pumps, valves and instruments, filters ensure system efficiency by preventing blockage and reducing component wear.
