J21W Pressure Gauge Valve
Core Function & Application Positioning
This low pressure needle valve adopts external thread connection and has a compact structure with a valve body height of only 50mm. Installed between the pressure gauge and the pipeline, it can realize on-line disassembly, assembly and maintenance of the instrument without shutting down the entire pipeline system. The low pressure needle valve is suitable for pressure monitoring scenarios of continuous production line operation, such as pressure detection of pipeline hydraulic equipment.
Material & Craftsmanship
The valve body is integrally processed with 304/316 stainless steel. The valve stem adopts an anti-loosening thread structure with a thread engagement depth of ≥5 teeth. The sealing element is aging-resistant fluororubber, which can operate stably for a long time in industrial working conditions. The valve body surface is plastic-sprayed for dual protection against corrosion and collision, ensuring the durability of the low pressure needle valve.
Specification Advantages
All specifications cover common external thread pressure gauge interfaces from M16×1.5 to M20×1.5, adapt to monitoring systems with different pressure levels from 0.6MPa to 40MPa, and are compatible with multiple brands of instruments such as Siemens and E+H.
Summary
The on-line disassembly and assembly function of this low pressure needle valve improves maintenance efficiency by 50%. The anti-loosening structure ensures long-term stability. The plastic-sprayed surface is corrosion and collision resistant. Its multi-interface adaptability makes it a convenient auxiliary component for pressure monitoring of industrial production lines, which can effectively ensure the continuous operation of the production line.
