Bolaisi Y-type strainers are dedicated pre-pipeline impurity filtration equipment manufactured under standardized production in our professional factory. Featuring an angled Y-shaped design, the strainer delivers low fluid resistance and enables easy disassembly and blowdown. Its removable internal screen traps rust, sediment, welding slag and granular contaminants, protecting downstream precision equipment including valves, pumps and instruments against abrasion and blockage.As a direct foreign trade manufacturer, we implement three rigorous quality inspection procedures: raw material flaw detection, hydrostatic pressure testing and screen mesh precision verification. Our products are widely exported to global industrial markets and serve as essential frontline protection fittings for water supply & drainage, chemical, oil & gas, and HVAC piping systems.

Flanged Check valves from manufacturer Bolaisi are fully automatic industrial valves designed to prevent backflow; they open and close automatically based on the pressure of the medium itself, requiring no manual intervention, electrical controls, or manual operation. Their core functions include allowing unidirectional flow, completely blocking backflow, protecting pipeline equipment, and preventing water hammer impact.

The flanged globe valve from supplier Bolaisi is a common dual-purpose valve used for shut-off and throttling in industrial piping systems. It features a flanged connection design and operates by moving the valve disc in a linear, vertical motion to control media flow and regulate flow rates. Unlike gate valves, which are limited to fully open or fully closed positions, globe valves offer key advantages such as precise throttling capability, durability against frequent cycling, reliable sealing performance, and ease of maintenance.

The flanged gate valve is a shut-off valve utilizing a flanged connection and a gate-style opening/closing mechanism; it is widely used in industrial piping systems. These valves see widespread application only after undergoing rigorous testing across various operating conditions and professional evaluation to ensure all performance indicators meet standards. Manufactured to standardized specifications by professional domestic enterprises, the product range covers nominal diameters from DN15 to DN1200 and is compatible with pipelines rated for PN10, PN16, PN25, PN40, and PN64 pressure classes.

Stainless Steel Flanged ball valves from supplier Bolaisi utilize a flanged connection and operate by rotating the ball 90 degrees to open or close the pipeline flow. Proven through testing across various operating conditions, these are versatile control valves widely used in industrial piping systems. They are mass-produced to standardized specifications by professional manufacturers, covering nominal diameters ranging from DN15 to DN400. Validated for use with media such as water, oil, gas, and steam, these valves feature significantly reduced flow resistance and rapid 90-degree actuation. Their stainless steel bodies offer excellent corrosion resistance and stable sealing performance. Available with various actuation methods—including manual, worm gear, pneumatic, and electric—they allow for precise control of flow and shut-off.

The Two Piece High Platform Flanged Ball Valve is a reliable industrial shut-off valve designed for general pipeline applications after extensive working condition tests. Manufactured by a professional valve manufacturer with standardized production processes, it is available in multiple sizes to meet different pipeline requirements.The ISO5211 standard high mounting platform on the valve top allows direct installation of electric or pneumatic actuators. With optional soft sealing and metal hard sealing structures, this ball valve is suitable for various applications involving low-temperature, high-temperature, and different industrial media.
