Product Overview: 

The butterfly valve is also known as the flap valve. It is a simple structure regulating valve that can be used for the on-off control of low-pressure pipeline media. The butterfly valve refers to a type of valve where the closing element (valve disc or butterfly plate) is a circular disc that rotates around the valve axis to achieve opening and closing. Valves can be used to control air, water, steam, various corrosive media, slurry, oil products, liquid metals, radioactive media and other types of fluid flows. On pipelines, it mainly serves the functions of cutting off and throttling. The butterfly valve's closing element is a disc-shaped butterfly plate, which rotates within the valve body around its own axis to achieve the purpose of opening or closing or regulation.

Product Overview: 

A ball valve is a type of valve widely used in fluid control systems. It controls the flow of fluid by rotating the valve core (ball). Its core structure consists of a ball with a circular hole. The ball rotates around an axis perpendicular to the pipeline axis to achieve the functions of opening, closing, or regulating. The product is widely applied in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, power, municipal services, and steel.

Product Overview: 

A gate valve has a gate plate as its opening and closing component. The movement direction of the gate plate is perpendicular to the flow direction. The gate valve can only be fully opened or fully closed, and cannot be used for regulation or throttling. The gate valve achieves sealing by the contact between the valve seat and the gate plate. Usually, the sealing surfaces are welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate plate has rigid gate plates and elastic gate plates. Depending on the type of gate plate, gate valves are classified as rigid gate valves and elastic gate valves.

Product Overview: 

The stop valve, also known as the cut-off valve, is a type of forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure that the sealing surface does not leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than that required to open it, so the diameter of the valve stem must be large; otherwise, the valve stem may be bent. According to the connection method, it is divided into three types: flange connection, thread connection, and welding connection.

Product Overview: 

A check valve is a type of valve whose closure element is a circular disc that moves due to its own weight and the pressure of the medium, thereby preventing the reverse flow of the medium. It belongs to the category of automatic valves and is also known as an anti-reflux valve, a one-way valve, a return valve, or a isolation valve. 

The filter is an indispensable device on the pipeline for transporting media. It is usually installed at the inlet end of pressure reducing valves, pressure relief valves, level control valves, and other equipment.

Product Overview: 

A regulating valve generally refers to a control valve. A control valve is composed of two main components: the valve body component and the actuating mechanism component (or actuating mechanism system). It is divided into four major series: single-seat control valve series, double-seat control valve series, sleeve control valve series, and self-operated control valve series. Variants of the four types of valves can result in numerous different applicable structures, each with its own specific applications, characteristics, advantages, and disadvantages. Regulating valves can be widely used in various precise control scenarios such as different temperatures, pressures, and flow rates.

Product Overview: 

A steam trap is generally referred to as a steam trap, also known as an automatic drain device or condensate discharge device. It is divided into two types: one for use in steam systems and the other for use in gas systems. The steam trap is installed at the end of the pipeline that is heated by steam, and its function is to continuously discharge the condensate water from the heated steam pipeline to the outside of the pipeline. 

Most water separators can automatically distinguish between steam and water (excluding thermal-static type), thereby achieving the purpose of automatically blocking steam and discharging water.

Forged steel valves refer to the valve devices used in various systems of thermal power plants to cut off or connect the pipeline media. 

Applicable media: Water, steam and other non-corrosive media. Compared with other valve products, the characteristic of forged steel valves is high temperature and high pressure, as well as a unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the performance and technical characteristics as well as the special working conditions, this product also forms features that other products cannot replace.

The knife gate valve, also known as the knife door gate valve or the knife type slurry valve, has a gate as its opening and closing component. The movement direction of the gate is perpendicular to the flow direction of the fluid. It cuts off the medium by relying on a blade-shaped gate with a cutting edge that can cut through fibrous materials. The knife gate valve entered China in the 1980s. In less than two decades, its application scope has expanded from the ordinary fields to a much broader range of industries. It has progressed from coal selection, gangue removal, and slag removal in mines and power plants to urban sewage treatment. It has also evolved from general industrial pipelines to professional pipeline systems in food, hygiene, and medicine.

Threaded valves (threaded valves) generally refer to valves with threaded connections. Threaded valves are a type of valve accessory, mainly referring to valves whose valve bodies have internal or external threads, and are connected to the pipeline threads. Valves with threaded connections are usually used in low-pressure engineering applications. However, they cannot be used in high-pressure valves, and instead, welded-linked valves or flange-connected valves should be used.

Product Overview: 

The needle-type instrument valve is a type of valve used for precise fluid control and is a key component in the instrument piping system. Its core feature is the use of a "needle valve core" - the valve core is in the shape of a sharp conical body, which can be precisely inserted into the valve seat. Through a small opening, it can achieve precise control of fluid flow and pressure, and at the same time, it has excellent sealing performance, suitable for scenarios with high requirements for precision and sealing, such as instrument measurement and industrial control systems.

Product Overview: 

The actuator is an indispensable and important component in an automatic control system. Its function is to receive the control signals sent by the controller, change the size of the controlled medium, and thereby maintain the controlled variable at the required value or within a certain range. Actuators are classified into three major categories based on their energy sources: pneumatic, hydraulic, and electric. 

Pneumatic accessories are an indispensable part of the pneumatic system. They control and regulate the flow of compressed air to achieve precise operation of pneumatic equipment.

Product Overview: 

Copper valves are valves made of copper. They are industrial parts. In China, the manufacturing process was first developed and produced in Ningbo, Zhejiang Province. In the early 1980s, Ningbo, Zhejiang Province took the lead in developing the manufacturing process, which changed the long-standing history of using cast iron valves in the country. In the manufacturing process, the initial method was sand casting, and in the early 1990s, it was changed to forging. By the beginning of the 21st century, China had become the world's manufacturing center for copper valves. 

Copper valves are valves made of copper alloys as the main material. By leveraging the corrosion resistance, thermal conductivity, electrical conductivity and good machinability of copper, they are suitable for various precision fluid systems.
