Valve
A ball valve is a quarter-turn rotary valve that uses a hollow, perforated, and pivoting ball to control fluid flow. It is widely used for on/off control, throttling, and isolation in pipelines due to its durability, reliability, and low maintenance.
A gate valve is a linear-motion valve designed to fully open or close fluid flow by raising/lowering a rectangular or wedge-shaped gate. It is widely used in industrial pipelines for isolation purposes due to its low flow resistance and tight sealing.
A globe valve is a linear-motion valve designed for precise flow regulation, shutoff, or throttling in pipelines. Its disc moves perpendicularly to the seat, ensuring reliable sealing and control. Widely used in steam, water, oil, gas, and corrosive media systems.
A check valve (also known as a non-return valve or one-way valve) is a mechanical device designed to allow fluid flow in one direction while preventing reverse flow. It ensures system safety, prevents backflow contamination, and protects downstream equipment.
A butterfly valve is a quarter-turn rotational motion valve used to regulate or isolate fluid flow. It consists of a circular disc (the “butterfly”) mounted on a rotating shaft, which controls flow by pivoting 90° from fully open to closed. Widely used in water treatment, HVAC, chemical, and oil/gas industries due to its compact design, quick operation, and cost-effectiveness.
Control valves are precision devices designed to regulate fluid flow, pressure, or temperature in industrial systems. They ensure stable process control by adjusting the flow area based on signals from controllers.
A safety valve is a critical pressure relief device designed to automatically release excess pressure from systems (e.g., boilers, pipelines, pressure vessels) to prevent catastrophic failures. It operates by opening at a predefined set pressure and reclosing once normal pressure is restored.
An angle valve (also known as a corner valve or shut-off valve) is a plumbing fixture designed to regulate or shut off water flow in pipelines. It features a 90-degree body design, making it ideal for tight spaces and corner installations. Commonly used in residential, commercial, and industrial systems for sinks, toilets, water heaters, and appliances.
