A high-pressure filter is a fluid purification device suitable for high-pressure environments. It can filter out impurities and particles in fluids, prevent clogging or wear of downstream valves, pumps and other equipment, and ensure the cleanliness and stable operation of high-pressure systems such as hydraulics and petrochemicals.

A high-pressure check valve is a valve suitable for high-pressure environments. It only allows fluid to flow in one direction and automatically prevents its reverse flow. It can protect equipment like pumps and compressors in high-pressure systems from overload or reverse flow impact, and is widely used in high-pressure fluid control systems such as hydraulic, pneumatic and petrochemical systems.

A needle valve is a type of valve withprecision flow/pressure regulation function. Its core feature lies in the precise matching structure of a "needle-shaped valve core" and a "conical valve seat," belonging to a special category of globe valves.By rotating the handwheel to drive the needle-shaped valve core to move axially, it changes the tiny gap between the valve core and the valve seat, thereby accurately controlling the on-off or flow rate of fluids (gases, liquids) while achieving excellent sealing performance (with minimal leakage under high pressure).Due to its precise structure, it is suitable for high-pressure, high-temperature, or low-flow working conditions. It is widely used in scenarios such as instrument measurement systems (e.g., cut-off/regulation before pressure gauges), fine adjustment of hydraulic systems, and sampling of high-temperature and high-pressure pipelines, serving as a key component for precise fluid control.

A high-pressure ball valve is a type of ball valve control device suitable for high-pressure working conditions (usually with a pressure ≥ 10MPa). Its core function is to quickly cut off or connect high-pressure fluids (gases, liquids, slurries, etc.), and it features reliable sealing and easy operation.It uses a ball as the valve core, and the on-off function is achieved by rotating the ball 90 degrees. The valve body is mostly made of high-strength materials (such as stainless steel, alloy steel). Sealing structures are divided into soft seals (suitable for medium-low to high pressure) and hard seals (suitable for ultra-high pressure and high temperature), ensuring no leakage under high pressure.Widely used in fields such as the petrochemical industry, high-pressure hydraulic systems, natural gas transmission, and power stations, it can resist high-pressure impact, and has the advantages of fast opening and closing as well as easy maintenance, making it a key control component in high-pressure fluid pipelines.

A pressure regulator is a control device that reduces high-pressure fluids (gases or liquids) to the required low pressure and stabilizes the output pressure. Its core function is to prevent damage to downstream systems or unstable working conditions caused by excessive pressure.
