J49W Pressure Gauge Valve (needle valve with gauge)
Core Function & Application Positioning
This needle valve with gauge adopts flange connection and a large-diameter design, suitable for pressure monitoring of DN20-DN50 large industrial pipelines, and can withstand high-pressure working conditions of 60MPa to ensure the stability of pressure data collection. The needle valve with gauge is suitable for long-term pressure monitoring of large petrochemical and metallurgical pipelines and can cope with pressure fluctuations of large-flow media.
Material & Craftsmanship
The valve body is forged with 304/316 stainless steel. The flange sealing surface adopts a concave-convex design, and the sealing reliability is twice that of flat sealing. The valve stem adopts a heavy-duty sealing structure that can withstand high-pressure and large-flow media. The valve body has passed ultrasonic flaw detection with no internal defects, ensuring the safety of the needle valve with gauge.
Specification Advantages
All specifications match different standard flanges such as national standard GB and American standard ANSI, cover high-pressure to ultra-high pressure levels from 16MPa to 60MPa, adapt to monitoring of large petrochemical and metallurgical pipelines, and support customized corrosion-resistant alloy materials.
Summary
The large-diameter design of this needle valve with gauge is suitable for large pipeline monitoring. The concave-convex flange seal prevents leakage. The high pressure resistance makes it a core component for pressure monitoring in heavy industries such as petrochemical and metallurgical. The ultrasonic flaw detection also ensures that the valve body has no internal defects, improving safety in extreme working conditions.
