Sanitary Stainless Steel Quick-Clamp Butterfly Valve with Aluminum Pneumatic Actuator

Sanitary Stainless Steel Clamp-Type Butterfly Valve with Aluminum Pneumatic Actuator

Product Overview

The Sanitary Stainless Steel Clamp-Type Butterfly Valve equipped with an aluminum pneumatic actuator is a fluid control device specifically designed for sanitary applications within the food, pharmaceutical, dairy, beverage, and bioengineering industries. Constructed from high-quality 304 or 316L stainless steel, the valve body features a precision-polished surface finish that meets stringent sanitary requirements. The clamp-style connection design ensures extremely convenient installation and disassembly, significantly reducing equipment maintenance time and costs. The pneumatic actuator, crafted from lightweight aluminum alloy, offers rapid response speeds and high control precision, enabling automated opening and closing of the valve; it is widely utilized in sanitary piping systems that require frequent cleaning and rapid maintenance.

Product Features

This valve series is designed with full consideration for the unique demands of sanitary environments, offering the following distinct features:

Material and Surface Finish: The valve body is constructed from 304 or 316L stainless steel. The inner walls are polished to a smooth finish with a surface roughness (Ra value) of less than 0.8μm, effectively preventing media residue accumulation and bacterial growth. All components in contact with the process media comply with international sanitary standards such as FDA and 3A.

Quick-Connect Clamp Design: Utilizes a standard clamp connection method compliant with international standards such as ISO 2852 and DIN 32676. The connection structure is simple, allowing for rapid disassembly merely by loosening the clamp, thereby facilitating Clean-In-Place (CIP) and Sterilize-In-Place (SIP) procedures.

Pneumatic Actuator Configuration: The aluminum alloy pneumatic actuator features a lightweight design, rapid response capability, and high torque output. It comes standard with a double-acting actuator, with an optional spring-return single-acting type available. The air supply ports utilize standard G-thread or NPT-thread connections, ensuring broad compatibility.

Reliable Sealing Performance: The valve seat is constructed from food-grade EPDM or PTFE materials, offering excellent resistance to temperature and chemical corrosion. A unique multi-point sealing design ensures zero leakage, while the seals are easy to replace, resulting in low maintenance costs.

Superior Flow Capacity: The flow channel design has been optimized to ensure the valve's nominal diameter matches that of the pipeline, resulting in minimal pressure drop and a high flow capacity coefficient (Cv value). The flow channel is smooth and free of dead spots, effectively preventing material clogging and accumulation.

Application Fields

Thanks to their superior sanitary performance and convenient maintenance features, stainless steel sanitary clamp-type butterfly valves equipped with aluminum pneumatic actuators are widely utilized across numerous industries:

Food & Beverage Industry: Used for pipeline control of food media such as beer, fruit juices, milk, and sauces. The clamp-type design facilitates the frequent cleaning demands of CIP (Clean-in-Place) systems, thereby ensuring sanitary production safety.

Dairy Industry: Extensively applied in processes such as pasteurization, milk conveyance, and the inlet/outlet ports of fermentation tanks. The corrosion resistance of the valve materials and their smooth surface finishes effectively safeguard product quality.

Pharmaceuticals & Bioengineering: High-sanitary-standard valves that meet GMP requirements, suitable for the precise control of media such as pharmaceutical liquids, injectable solutions, and biological products. These valves are capable of withstanding high-temperature sterilization processes.

Cosmetics & Personal Care: Employed in systems for the conveyance and blending of raw materials for products such as skin creams, lotions, and shampoos. The valves' excellent sealing performance ensures that the media remain free from contamination.

Water Treatment & Purification Systems: Serve as critical control components in systems for purified water and Water for Injection (WFI), meeting the stringent requirements of ASTM standards and various pharmacopoeias.

Installation & Maintenance

During installation, ensure that the pipeline is clean to prevent foreign objects from entering the valve body and compromising the sealing integrity. Clamp connections require the use of high-quality gaskets that comply with relevant standards to ensure a reliable seal. The pneumatic actuator must be paired with an air preparation unit—comprising filtration, pressure regulation, and lubrication components—and the air supply itself should be kept dry and clean.

Routine maintenance primarily focuses on the inspection and replacement of sealing components. It is recommended to inspect the valve seat seal after the completion of each production cycle; any signs of wear or aging should prompt immediate replacement. The actuator cylinder should undergo periodic lubrication and maintenance to ensure smooth and reliable operation.

For long-term storage, the valve should be kept in a closed position, with the sealing surfaces coated in a food-grade lubricant for protection. The storage environment should be dry and well-ventilated, free from exposure to corrosive media. Selection Recommendations

When selecting a valve, the following factors should be comprehensively considered based on actual operating conditions: the characteristics of the medium (corrosiveness, temperature, and viscosity) determine the choice of body and sealing materials; the nominal pressure and pipeline specifications determine the valve's nominal diameter; control requirements (on/off or modulating control) determine the type of actuator; and available installation space and pneumatic supply conditions influence the selection of the actuator's specifications. It is recommended to consult fully with professional technical engineers to ensure that the selected solution meets both process requirements and sanitary standards.
