Is the Needle Control Valve with BSP Female Thread, EWO compatible with gases other than air, such as nitrogen or carbon dioxide?

Yes. The Needle Control Valve with BSP Female Thread, EWO is designed primarily for air but is explicitly suitable for non-flammable, non-toxic gases such as nitrogen and carbon dioxide (as well as helium or argon). Its brass body and needle, together with NBR stem sealing, provide durable, tight performance across a wide temperature range (-10°C to +90°C) and at working pressures between 25 and 40 bar depending on DN size. Ensure compatibility with your specific process conditions (pressure, temperature, and gas purity) and any industry regulations before use.

Needle Control Valve with BSP Female Thread, EWO

Q: Can the Needle Control Valve with BSP Female Thread, EWO withstand continuous operation at pressures up to 40 bar across all DN sizes?

Needle Control Valve with BSP Female Thread, EWO can withstand continuous operation at pressures up to 40 bar only for those DN sizes rated for that pressure. According to the product description, the valve supports constant working pressures between 25 and 40 bar depending on the DN size — some DN variants are limited to 25 bar, while others are rated up to 40 bar. Verify the specific DN rating for your chosen size (from the manufacturer's datasheet or label) before running continuous service at 40 bar.

Additional information

Material	B – brass (bronze)

The needle control valve with BSP internal thread ensures precise regulation of fluid flow by smoothly adjusting the cross-section of the passage, allowing for fine control up to complete shut-off. Designed primarily for air installations, it is also perfectly suited for use with non-flammable and non-toxic gases such as nitrogen, carbon dioxide, helium, or argon, making it a versatile solution for a wide range of industrial applications. Its robust brass body and brass needle guarantee durability and resistance to wear, while the NBR stem sealing ensures reliable tightness even under demanding conditions. The valve operates efficiently across a wide temperature range from -10°C to +90°C, withstanding constant working pressures between 25 and 40 bar depending on the DN size. A clear flow direction indicator on the body simplifies installation and ensures correct operation. Combining precision, reliability, and long service life, this valve is an excellent choice for professionals seeking dependable flow control in pneumatic and gas systems.
