UNILOK offers UHP diaphragm valves, UHP high- and low-diaphragm valves, and UHP regulators for ultra-high-purity applications. It controls fluid or gas flow without leaks and precise flow control.

UNILOK Low Pressure Diaphragm Valve

The UNILOK low pressure diaphragm valve is engineered for precise control and reliable shut-off in low-pressure fluid systems. It is particularly well-suited for applications where cleanliness, leak-tight sealing, and corrosion resistance are critical requirements, such as semiconductor manufacturing, pharmaceutical production, and ultra-pure water systems. This valve performs accurately even under low-pressure conditions, making it ideal for sensitive and delicate processes. Its compact and lightweight design allows for easy installation in confined spaces or tight system layouts.

The valve features a soft diaphragm — a flexible membrane that ensures complete shut-off of flow, delivering zero leakage performance. Constructed from robust materials such as stainless steel, it offers exceptional resistance to corrosion, even when exposed to harsh chemicals and aggressive fluids. The smooth internal surface minimizes dead space, reducing the risk of fluid entrapment and contamination, thereby supporting clean and hygienic operation. A clear visual indicator provides users with an immediate view of the valve’s open or closed position, enhancing operational safety and convenience. The UNILOK diaphragm valve can be operated manually or integrated into pneumatic systems for automated control, offering flexibility based on system requirements.

Typical applications of this valve include semiconductor and electronics manufacturing, pharmaceutical and biotechnology processing, food and beverage production, laboratory gas and fluid control, and water treatment systems. Its combination of precision, cleanliness, durability, and ease of operation makes it a dependable solution for demanding low-pressure fluid control environments.
