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.

Stainless Steel Flange Butterfly Valves features a flange type, providing more stable performance when near vibrations caused by the pump. Additionally, the body of the stainless steel flange butterfly valve is made of stainless steel, which offers better resistance to corrosion from the external environment

A hydraulic actuator concentric butterfly valve Produced by ZHONGGUAN valve combines the features of a concentric butterfly valve with a hydraulic actuator for automated operation. 

This WCB Two-Piece Flanged Floating Ball Valve from Zhongguan Valve is a durable product specially designed for factories. It is made of high-quality carbon steel and is extremely sturdy. It can withstand temperatures up to 425 degrees Celsius and is not afraid of high pressure. It can fully meet the requirements of various harsh working conditions. The valve is internally designed with a floating ball, and the greater the pressure, the better the sealing effect. There is no need to worry about leakage problems.
