Pharmaceutical mini diaphragm valve with lock-out capability manufacturers

Hygienic mini manual diaphragm valve with safe lock is a valve that controls the fluid on/off and flow rate through manual operation and has a locking function. It has the characteristics of compact structure and good sealing, and is widely used in many fields such as pharmaceutical, food and beverage, industrial production etc.

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.
• Mini Design: Compact, small, and lightweight, it is suitable for applications where space is limited, such as laboratory analytical instruments and microfluidic chips.
• 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:

• Laboratory Analysis: Used in instruments such as liquid chromatography and mass spectrometry for precise dispensing of trace reagents, the valve's flow channel diameter can be as small as 0.1mm, with a repeatability of ±0.5%.
• Biomedicine: In drug delivery systems or dialysis equipment, medical-grade silicone diaphragms, which withstand gamma ray sterilization to ensure biocompatibility, are used for precise control of drug flow.
• Food and Beverage: The valve's simple structure resists dirt and facilitates cleaning and disinfection, meeting the strict hygiene requirements of the food industry and can be used for flow control in beverage production lines.
• Electronics Manufacturing: Used in semiconductor wet etching equipment to control the flow of high-purity chemicals, the valve body is made of PFA or perfluoroelastomer, achieving metal ion leaching levels below 1ppb, meeting the high cleanliness requirements of the electronics industry. Industrial Production: Used in the chemical, electroplating, photovoltaic, and other industries to control the flow and flow of media containing small amounts of particles and solids, such as landfill leachate and plating solutions.

The mini manual diaphragm valve with lock is a valve that controls the fluid on/off and flow rate through manual operation and has a locking function. It has the characteristics of compact structure and good sealing, and is widely used in many fields.

The locking mechanism design of the mini manual diaphragm valve with a lock offers significant practical value. In addition to the aforementioned uses, it also plays a crucial role in ensuring production safety and improving product quality.

Ensuring Production Safety: When the valve is closed, the locking mechanism acts as a solid "physical lock" on the valve stem. Regardless of pressure shocks from the fluid in the pipeline or vibrations from on-site equipment operation, the disc's position cannot be disturbed. This completely eliminates the risk of internal leakage caused by accidental valve movement, providing a solid defense for process safety and environmental protection.                                                                                                                    

Improving Product Quality: In industries with extremely high product quality requirements, such as pharmaceuticals and food, the manual diaphragm valve with a lock can adjust the disc to the desired opening position based on production process requirements and then secure it with a locking mechanism, ensuring that the valve opening remains unchanged during production. In the pharmaceutical industry, for example, this feature has increased the yield rate of pharmaceutical production from 85% to over 95%, ensuring stable and consistent product quality.
