Product Overview
The CARTEN CB 751 Bellows Valve is a precision-engineered process valve designed for reliable isolation and control of aggressive, toxic, or high-purity media in industrial fluid systems. Manufactured by CARTEN, a recognized name in process and pneumatic valve technology, the CB 751 utilizes a hermetically sealed bellows stem design that eliminates dynamic stem seal leakage and prevents media exposure to the atmosphere. Unlike conventional packed-stem valves, the welded or formed metal bellows acts as a barrier between the process fluid and the actuator environment, making this valve ideal for applications involving hazardous chemicals, volatile fluids, and ultra-pure gases. The CB 751 is a direct-acting, pneumatically or manually actuated valve suitable for integration into automated process lines, hydraulic control circuits, and pneumatic distribution systems where zero-leakage performance and long cycle life are mandatory.

Engineering Features & Advantages
- Hermetic Bellows Seal: The welded metal bellows provides a leak-tight barrier between the process medium and the external environment, eliminating fugitive emissions and protecting personnel from hazardous fluids.
- Extended Cycle Life: The bellows element is designed for high-cycle fatigue resistance, ensuring consistent sealing performance over millions of actuations without the maintenance demands of traditional packing.
- Corrosion-Resistant Construction: Body and wetted parts are available in stainless steel and other corrosion-resistant alloys, suitable for aggressive chemical and high-purity applications.
- Precise Flow Control: The valve trim is engineered for accurate throttling and tight shutoff, maintaining stable flow characteristics across the operating range.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, including elevated temperatures and pressures.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original CARTEN CB 751 specifications and OEM interface standards.
Typical Industrial Applications
The CARTEN CB 751 Bellows Valve is deployed across a wide range of demanding industrial sectors, including chemical and petrochemical processing plants where toxic or volatile media must be contained, pharmaceutical and biotechnology manufacturing requiring sterile and contamination-free fluid handling, semiconductor and specialty gas systems demanding ultra-high-purity performance, and hydraulic power units and test stands where zero-leakage isolation is critical. It is also commonly found in research laboratories, water treatment facilities, and food processing lines where hygiene and reliability are paramount.
