High-Precision Industrial Metal Stem Metering Valve for Critical Process Flow Regulation with Calibrated Dosing Accuracy

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.

Future industry manufacturing complex spans an area of nearly 7,000 square meters. It incorporates six high-speed aerosol valve production lines and more than 30 special valve production lines.

Each year, Future industry aerosol can produce up to one billion aerosol valves. Our main products are air freshener aerosol valve, insecticide spray aerosol valve, butane gas aerosol valve, carburetor cleaner aerosol valve, ribbon spray aerosol valve, snow spray aerosol valve,paint spray aerosol valve, fluid spray aerosol valve, portable stove gas aerosol valve, 360 degree aerosol valve, powder spray aerosol vave. Also we have expanded the export market of aerosol metering valves, aerosol caps and aerosol cans.We have also built five standardized workshops to conduct different operations in order to meet the requirements of various customers to ensure we always meet production demands and timelines.

Production of the valve mounting cups is carried out in this workshop. We use a high-speed automatic stamping machine to transform high-quality steel plates into valve mounting cups. Due to the high degree of its automation, this equipment can help to reduce labor costs and increase production efficiency significantly.

In addition, we utilize an efficient machine that can automatically press an outer rubber ring into a valve mounting cup in order to provide superior sealing performance in the process of final assembly.

This workshop contains over 20 injection molding machines and three injection molding lines. Among them, our injection molding machines are used to produce a variety of accessories such as valve stems, valve chambers, actuators, and spray caps, etc.

Due to efficient automation, we require a very small number of staff to run these more than 20 injection molders. During the production process, our quality control inspectors are responsible for sampling and testing every batch of accessories. Additionally, our injection molding line has the capability to produce various sizes of dip tubes in automatic mode.

This workshop is used to assemble all kinds of accessories. It is equipped with automated assembly equipment to greatly increase production efficiency and provide our customers with enhanced profits.

After assembly is completed, our valves will be automatically counted and packed. We are proud to say we are one of the few companies in the industry that possess advanced abilities in product research and development. Every new product needs an innovative mold. For this reason we utilize high-precision wire cutting machines and machine tools that can form our molds into exquisite shapes.

We possess a wide range of technical production and R & D expertise
