CNLD check valves are designed to prevent reverse flow and protect pipelines in industrial systems. By allowing fluid to flow in only one direction, these valves automatically stop reverse flow for safety purposes and equipment protection. Whether in wastewater treatment, mining, or general industrial process systems, a check valve is required to prevent backflow and ensure stable operation. CNLD offers high-performance swing, lift, and wafer check valves made from stainless steel, ductile iron, and carbon steel, with pressure ratings from PN10 to PN40. If you’re wondering what a check valve does, it keeps your media moving forward, clean, and controlled.

The gate valve is a closed -closed gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be opened and full. '. Improve its craftsmanship and make up for the deviation of the cover angle during processing. This gate is called elastic gate.

The deadline valve is suitable for cutting or adjustment and throwing. Because the valve stems of this type of valve are relatively short, and they have a very reliable cutting function, and due to the changes in the valve seat pass and the stroke of the valve petals, it is very suitable for adjusting the flow. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

The ball valve is mainly used for cutting, allocation, and changing the flow of the medium on the pipeline. The ball valve designed as the V-shaped opening also has a good flow adjustment function. The ball valve is suitable for frequent operation, and the opening and closing are quickly and light. It also has small fluid resistance, simple structure, relatively small volume, light weight, and easy maintenance. The sealing performance is not limited by the direction of installation, and the flow of the medium can be arbitrarily.

As a leading China butterfly valve manufacturer, CNLD produces high-quality valves for global industrial applications. Our butterfly valves are designed to control fluid direction, pressure, and flow rate, playing a key role in cutting off or throttling within pipeline systems. Thanks to their precision design, butterfly valves can fine-tune flow without full closure, making them ideal for applications requiring accurate control.

Strainers are essential components in fluid systems. They are installed on pipelines to filter out solids and protect downstream equipment such as pressure reducing valves, pumps, and control valves. Our range includes Y type, T type, and Basket type strainers. Each unit consists of a durable body, stainless steel mesh, sewage chamber, and connection ports. These strainers help prevent clogging, reduce equipment wear, and ensure smooth system operation. Strainers are widely used in water supply, HVAC systems, industrial process pipelines, and chemical flow control.
