Sanitary manual tri clamp diaphragm valves with safety lock

DONJOY lockable sanitary manual diaphragm valve features a locking mechanism at the valve stem position. After turning the handwheel to move the valve stem and valve disc to the desired position, simply operate the locking mechanism to fix the valve disc in place, ensuring it won't move arbitrarily. This ability to precisely control and lock the valve disc position makes it stand out among many ordinary manual diaphragm valves, making it a more flexible and precise option in the field of industrial fluid control.

Traditional hygienic manual valves are prone to displacement when faced with pressure fluctuations, system vibrations, or accidental impacts. This "hidden threat" has become a pain point for many companies and users, especially in critical processes in industries such as chemical, pharmaceutical, and water treatment. The leakage risk or adjustment deviation caused by accidental valve loosening can range from affecting production quality to causing safety accidents. Faced with this troublesome problem, engineers and customer service overcame various difficulties and ultimately developed a solution: adding a small lock to the diaphragm valve. This ensures production safety, improves product quality, achieves precise control, and reduces operating costs.

Product Features:

• Locking Function: A locking mechanism is designed into the valve stem. Turning the handwheel to control the valve stem moves the disc into the desired position, securing it in place. This prevents displacement due to pressure fluctuations, system vibration, or accidental collisions, ensuring stable valve opening and enhancing safety and control accuracy.
• Excellent Sealing Performance: The diaphragm and valve seat create a surface-to-surface seal, eliminating the need for packing or O-rings, preventing particle entrapment. The diaphragm completely isolates the drive components from the fluid, preventing cross-contamination and ensuring excellent leak-free operation.
• Corrosion Resistance: The valve body and diaphragm are made of a variety of corrosion-resistant materials, offering resistance to corrosive media such as strong acids, bases, and organic solvents, making them suitable for a wide range of chemical environments.
• Convenient Operation: The screw-type design provides smooth operation, facilitates precise control of the valve's opening and closing position, and is easy to assemble and disassemble for maintenance.

Applications:

• Food and beverage industry: Strictly guarding the line of defense for food safety
• In food and beverage production, hygiene and safety are paramount. The lockable manual diaphragm valve features a simple design, free of complex internal structures and dead corners, making it less prone to dirt accumulation and easy to clean and disinfect, thus meeting the stringent hygiene requirements of the food industry. On beverage production lines, precise control of liquid flow is crucial at every stage, from raw material transportation and blending to finished product bottling. Lockable manual diaphragm valves are installed at key points, allowing operators to precisely adjust the valve opening according to formula requirements. The locking mechanism ensures that the valve opening remains unchanged during production, guaranteeing a stable ingredient ratio and consistent taste in every bottle of beverage. Simultaneously, its excellent sealing effectively prevents external impurities from entering the pipeline, avoiding food contamination and safeguarding food safety at every stage.
• Pharmaceutical Industry: Key to Ensuring Drug Quality
• The pharmaceutical industry has extremely stringent requirements for production environment and equipment, with every parameter in the drug production process directly affecting the quality and efficacy of the drugs. Lockable manual diaphragm valves play an irreplaceable role in the pharmaceutical field, their precise flow and pressure control meeting the stringent process requirements for raw materials, intermediates, and finished products. In the aseptic preparation workshop of a pharmaceutical company, lockable manual diaphragm valves are used in the drug preparation and filling processes. By precisely adjusting the valve opening, the accurate content of each batch of drugs is ensured, improving the stability and consistency of drug quality. Moreover, the high sealing performance when the valve is closed and the locking mechanism preventing internal leakage effectively avoids microbial contamination and cross-contamination, providing reliable assurance for drug quality.
• Chemical industry
• Water treatment industry.

How to locking and unlocking the valve?

Unlocking operation: Pull out the self-locking handle and rotate it approximately 90 degrees.
Locking operation: Rotate the self-locking handle to make it automatically reset.
