Engineered for Versatility and Precision

The hand valves durable brass construction and adaptable mounting options make it a reliable fit for a broad range of pneumatic and industrial automation scenarios. Its compact, 1/4-inch BSP female ports support easy in-line or panel installations, offering flexibility in new setups or retrofits. The plastic lever handle ensures comfortable manual operation, while the bubble-tight seal guarantees minimal leakage, every time.

Optimized Safety and Longevity

With a working pressure range up to 10 bar and a temperature tolerance from 0C to 60C, this valve is designed to withstand demanding industrial environments. The nickel-plated, polished surface wards off corrosion, and the NBR seal material ensures secure, leak-free use even with repeated cycles. Its compliance with ISO 9001 standards confirms its reliability, precision, and consistent performance in critical applications.

FAQs of Hand valve:

Q: How is this hand valve installed in a pneumatic system?

A: This hand valve can be mounted either in-line or on a panel using its female-to-female BSP threaded ports. Installation requires securing the valve to the pipeline or within an equipment panel, making it adaptable to various pneumatic layouts.

Q: What are the main advantages of using a brass, nickel-plated hand valve with NBR seals?

A: The brass construction provides excellent strength and durability, while the nickel plating resists corrosion. NBR (Nitrile rubber) sealing ensures a tight, leak-free closure, even with frequent use, thereby enhancing the valves longevity and reliability.

Q: When should I use this hand valve in an industrial automation setup?

A: This valve is ideal for controlling or isolating the flow of air or inert gas in pipelines, air compressors, or machinery whenever manual intervention is required, especially where precision shutoff or moderate pressure is essential.

Q: Where can this hand valve be utilized besides pneumatic systems?

A: Beyond pneumatic systems, the valve is suitable for any application requiring manual control of inert gas or air, such as industrial machinery, laboratory setups, and automation processes that demand precise flow regulation.

Q: What process steps are involved in operating this hand valve?

A: To operate, simply turn the plastic handle to open or close the valve, thus starting or stopping the flow through the connected pipeline. The round knob allows for comfortable, manual adjustments and precise flow management.

Q: What are the usage benefits of this bubble-tight hand valve?

A: Its robust design and minimal leakage help maintain system efficiency and safety. The high hardness rating, accuracy, and ISO compliance result in reliable, consistent performance, reducing maintenance and downtime.
