Engineered for resilience and reliability, our heavy-duty 20mm metered valve is built to handle the most demanding industrial and agricultural applications. This robust metering valve is designed to dispense accurate doses of viscous chemicals, lubricants, solvents, and pesticides with unwavering reliability, even in challenging environments. It features a large-orifice, clog-resistant design that minimizes the risk of blockage from particulate matter in suspensions or concentrates. Constructed with chemically inert materials including PTFE seals and specially coated springs, the valve offers exceptional resistance to corrosion and aggressive substances. The reinforced actuator and heavy-duty spring require higher actuation force, preventing accidental discharge and ensuring operator safety. This industrial-grade valve delivers consistent dosing precision from 100μl to 500μl, making it an indispensable component for products where accurate, safe, and reliable chemical dispensing is non-negotiable.

Bullet Points

• ⚙️ Clog-Resistant Operation: Features a large fluid pathway and self-cleaning mechanism that reduces the risk of clogging, even with viscous or particle-filled formulations like pesticides and lubricants.

• ⚙️ Chemical Resilience: Built with advanced polymer seals and coated components that withstand prolonged exposure to aggressive chemicals, acids, and solvents without degradation.

• ⚙️ High-Volume Metering: Capable of accurately dispensing larger metered volumes (up to 500μl) required for industrial applications, with consistency ensured by a robust internal mechanism.

• ⚙️ Safety-First Design: The higher actuation force and often included dust cap prevent accidental release, ensuring safe handling, transport, and storage of hazardous chemicals.

• ⚙️ Durable Construction: Engineered for a long service life with materials chosen for their wear resistance and ability to perform under a wide range of environmental conditions.

Specific Application Scenario

In an agricultural chemical plant, this 20mm metered valve is used on a line of professional-grade herbicide sprays. The valve is designed to dispense a precise 250μl dose of concentrated herbicide with each actuation, allowing users to target weeds accurately without overspray that could damage nearby crops. The clog-resistant design is critical here, as the formulation contains suspended particles. The valves are crimped onto chemical-resistant HDPE containers on a dedicated, ventilated filling line, with each batch documented for traceability to meet stringent agricultural safety standards.

FAQ

• What is the maximum viscosity this valve can handle?
  The heavy-duty design can reliably handle formulations with viscosities up to 5,000 cP, making it suitable for thick oils, pastes, and suspensions.

• Are these valves compatible with all common agricultural chemicals?
  While highly resistant, compatibility depends on the specific chemical. We provide comprehensive chemical resistance charts and recommend testing with novel formulations.

• Can the valve be used for products requiring a higher burst pressure?
  Yes, this series is tested to withstand higher internal pressures (up to 1.5 MPa) compared to standard valves, suitable for certain industrial applications.

• Is the actuator design child-resistant?
  While the higher actuation force offers some inherent resistance, we can provide certified child-resistant actuator caps upon request to meet specific regulatory requirements.

• What is the lead time for customizing the valve for a specific chemical?
  Lead time for material compatibility testing and custom calibration typically adds 3-4 weeks to the standard production schedule.
