DIN Standard Bellows Sealed Globe Valve

The Zhongguan DIN Standard Bellows Sealed Globe Valve is engineered for superior reliability, durability, and leak-proof performance in demanding industrial systems. Designed with precision and high-quality materials, this valve is ideal for hot oil systems, steam systems, and hot and cold water pipelines.

Product Overview

The stem assembly of this bellows-sealed globe valve adopts a stainless steel bellows to achieve airtight sealing. The bellows are integrated inside the valve, with the lower end welded to the stem to effectively prevent corrosion from system fluids. The upper end is securely crimped between the valve cover and body, forming a long-lasting and maintenance-free seal. Its compact structure ensures reliable operation even under high temperature and pressure conditions.

Core Advantages of Zhongguan Bellows Globe Valves

1. Metal Bellows Sealing Core

The heart of the valve is its metal bellows assembly, crafted using an automatic roll welding process. This ensures a tight dynamic seal between the valve stem and cover, preventing leakage from the stem area and providing superior durability in high-pressure and high-temperature environments.

2. Conical Streamlined Disc Design

The uniquely tapered and streamlined disc design ensures a smooth flow path, minimizes turbulence, and enhances sealing reliability. This innovative structure extends the service life of the disc while improving overall valve performance.

3. Bellows Packing Double Seal Guarantee

The valve combines bellows sealing with secondary packing for maximum leak protection. The bellows act as the primary seal, isolating the media from the stem, while the packing serves as a backup seal. Together, they create a double-layered sealing barrier that is highly reliable and long-lasting.

4. Integrated Oil Injection Nozzle

The valve features a dedicated oil injection nozzle, enabling direct lubrication of key moving parts, including the stem, stem nut, and guide sleeves. This reduces friction, prevents wear, and ensures smooth and efficient valve operation over time.

5. Ergonomic Hand-Wheel Operation

The hand-wheel is designed for ergonomic comfort, reducing operator fatigue and ensuring smooth, precise control. Its lightweight and robust construction enhances durability, making operation easier and safer, even in demanding industrial environments.
