Frequently Asked Questions (FAQ)

What is the maximum working pressure for these needle valves?

The JNV Series needle valves are designed to handle high-pressure environments with a maximum inlet pressure of up to 5000 psig (345 bar).

Are these valves suitable for ultra-high purity (UHP) gas delivery?

Yes, the valves feature an electropolished surface finish (Ra < 5 µin) to minimize particle generation and adsorption, making them ideal for semiconductor and cleanroom applications.

What materials are used for the diaphragm and seats?

We use high-grade materials including Hastelloy® C276 or 316L stainless steel for diaphragms and PCTFE for the valve seats to ensure chemical compatibility and durability.

Can the valves operate in high-temperature environments?

The JNV Series has a broad temperature tolerance, operating reliably from -54ºC up to +232ºC, suitable for atomic layer deposition (ALD) and other thermal processes.

Is customization available for small order quantities?

Yes, we provide customization services for small quantities to meet specific laboratory or industrial requirements, including various flow patterns and connection types.

What is the leak rate performance of these valves?

The valves offer exceptional sealing performance with a leak rate to atmosphere of 1×10-8 Mbar I/S He and via the seat of 1×10-6 Mbar I/S He.
