DIN check valves offer high reliability in critical industrial systems through standardized design, durable materials, and rigorous testing. Key selection factors include media compatibility, pressure/temperature ranges, and DIN/ISO certification.

DIN Standard Angle Type Bellows Sealed Globe Valve,The angle design transforms a standard globe valve into a space-saving, drainage-optimized solution for complex piping layouts, while enhancing sealing reliability and maintenance efficiency—making it indispensable in critical industrial systems governed by DIN standards.

Zhongguan Valve Manufacturing Company produces worm-driven split-type butterfly valves. These valves are widely used in numerous industrial systems. Unlike other butterfly valves, it adopts a double eccentric design. The wear of the sealing surface will be reduced, and the sealing performance and durability will also be improved, making it suitable for high-pressure, high-temperature and high-flow working environments. The structure of the worm-driven split-type butterfly valve is relatively simple. What materials are used to make the valve body and valve disc of this type of valve? Different from other products, it is made of alloy steel. The valve seat is made of polytetrafluoroethylene material. Among various types of valves, the worm-driven split-type butterfly valve can effectively control the flow of fluids and is applied in industries such as petroleum, chemical engineering, power and water treatment.

The DIN Standard Globe Valve are designed and manufactured in strict accordance with DIN 3356, BS 1873 and EN 13709/EN 12516 standards, and the length of the structure complies with DIN 3202 and EN 558-1. Flange interface (FF/RF/RTJ type) is standard according to EN 1092-1 and DIN 2543~2550 series. The testing system implements DIN 3230 specifications, and the pressure ratings cover the range from PN16 to PN100.

The stem assembly of the bellows seal shut-off valve adopts bellows for airtight sealing, and the structure is more compact. The bellows are located inside the DIN Standard Bellows Sealed Globe Valve, and its lower end is welded with the stem and is made of stainless steel, which effectively isolates the corrosion of the system fluid on the stem. The upper end of the bellows is crimped between the valve cover and the valve body to form a long-lasting and reliable seal.

The Single Disc Check Valve launched by Zhongguan Valve is an extremely useful industrial valve. Its main function is to allow liquids or gases to flow in only one direction, preventing backflow. This valve is ingeniously designed, reacts very quickly, and is easy to install, taking up little space. It can effectively control the flow direction for water, oil, or gas. It can be used in water treatment plants, power stations, chemical plants, heating and air conditioning systems, etc. This valve is particularly sturdy and can withstand high pressure and high temperatures. It won't break even after being used for a long time and is a very reliable choice in industrial pipeline systems.
