High-Precision Industrial Metal Stem Metering Valve for Critical Process Flow Regulation with Calibrated Dosing Accuracy
Product Description:
Engineered for exacting fluid management applications, our metal stem metering valve delivers unparalleled flow control accuracy in demanding industrial environments. This precision-engineered flow regulation device features a hardened stainless steel stem with micro-finished threading (Ra ≤ 0.8μm) that achieves ±0.5% dosing repeatability across 10,000+ cycles. The metering mechanism incorporates a tungsten-carbide seating surface and PTFE-backed stem seal, ensuring leak-tight shutoff (<0.0001 ml/min) even with aggressive media like acids, solvents, or high-pressure gases. Designed for process control systems in chemical injection, pharmaceutical batching, and fuel blending, the valve body withstands 6,000 PSI operating pressures with ANSI B16.34 compliance. Our calibration-certified assembly includes NIST-traceable flow curves for 15 standard orifice sizes (0.5-12mm). The stem-guided design eliminates wobble during partial opening, maintaining precise Cv values from 0.01 to 4.2. Ideal for automated dosing skids requiring ISO 15848 fugitive emission certification.

Bullet Points:
±0.5% dosing accuracy with NIST-traceable calibration certificates
Hardened 17-4PH stainless stem resists galling and wear
Zero-leak performance per ISO 15848 FEA Class A
15 interchangeable orifice sizes for flow range optimization
100ms response time for automated process control
Specific Application Scenario:
In chemical injection systems for oil pipelines, the valve precisely doses 2.3 ml/min of corrosion inhibitor into high-pressure flow lines (420 bar). Operators adjust the micrometer-scale stem position quarterly based on viscosity changes.

FAQ:
Q: What stem sealing options exist for cryogenic service?
A: Our metal stem design supports Graphoil® or spring-energized seals for -196°C.
Q: Can valves be supplied with ATEX certification?
A: Yes – metering valves available with ATEX II 2G Ex db IIC T6.
Q: Lead time for custom orifice sizes?
A: 8 weeks for non-standard metering mechanisms.
Q: Maximum particle size tolerance?
A: 15μm recommended – larger particles risk damaging the precision seating.
Q: Documentation for FDA-compliant applications?
A: Full material traceability (CDX) provided for process control in pharma.
