Blastline USA Suction Abrasive Metering Valve
The Blastline USA suction abrasive metering valve is designed for controlling abrasive media flow in blast cabinet applications. It features an adjustable mechanism with a locking stem for secure, repeatable settings in demanding environments. The valve’s stainless steel globe body provides durability and corrosion resistance, making it suitable for long-term use in abrasive media systems. This valve is intended for use with blast cabinets and similar suction-based setups where precise dosing is critical.
Blastline USA Metering Assembly Valve
The Blastline metering assembly valve, featuring a rubber cap and an old-style design, is crafted for compatibility with sand blast cabinets and other suction gun setups. It provides a reliable metering option for abrasive and chemical blends, enabling steady control in heavy-duty blasting operations. The assembly is designed to integrate with varied suction configurations, making it a versatile choice for pro shops and industrial settings.
Soft Wash Mixing Manifold 3 Port
The Soft Wash Mixing Manifold provides a three-port configuration for combining water, detergent, and other additives in fixed proportions. Made in the USA, it features 1″ NPT holes and multiple mounting holes for secure installation. This manifold simplifies on-site mixing and delivery to the soft wash spray system, helping maintain consistent chemical ratios across different workflows.
1/2″ FNPT x 1/2″ FNPT Polypropylene Check Valve
This polypropylene check valve features FKM seals and a Hastelloy spring, offering chemical compatibility and reliable backflow prevention in soft wash lines. With 1/2″ FNPT connections, it is well-suited for small-to-medium scale applications where chemical safety and corrosion resistance are priorities. The valve’s material choices help resist degradation in harsh wash solutions and detergents.
Ultimate Washer UW16-PW70B3 Adjustable Soap Injector
The Ultimate Washer UW16-PW70B3 injector is designed for adjustable soap and chemical delivery in pressure washer systems. It supports 2000-4000 PSI and 2-5 GPM, requiring standard 3/8-inch quick-connect hoses. This injector kit includes the injector, tubing, and filter, and is compatible with 3/8-inch inner-diameter hoses. It is intended for use where controlled chemical dosing is needed during high-pressure cleaning tasks.
Downstream Chemical Injector, High Draw
The Downstream Chemical Injector from Soft Wash depot offers multiple draw options (1.8 mm, 2.1 mm, 2.3 mm) tailored for varying flow rates in downstream injection setups. It provides flexibility for adapting chemical concentrations in wash solutions, supporting 2-3 GPM to higher ranges depending on nozzle and pump configurations. This option is useful for applications needing precise dilution ratios in real-time.
GF Signet PVC Metering Ball Valve
The GF Signet PVC Metering Ball Valve is a simple, durable option for basic metering needs in PVC piping systems. PVC construction offers resistance to many chemical solutions used in soft wash operations, and the unit is designed for easy integration into standard 1/2″ NPT fittings. This valve provides reliable flow control for routine metering tasks in smaller or less demanding setups.
Buying Guide: Key Purchase Considerations
- Material compatibility: Select valves and injectors made of stainless steel, brass, or high-grade plastics (PVC, polypropylene) depending on the chemicals used. Consider seals (FKM, silicone) and springs ( Hastelloy) for chemical resistance and long life.
- Connection sizes and fittings: Check your system’s hose and pipe diameters (FNPT, NPT, 1/2″, 3/8″) to ensure proper compatibility and minimal leaks. Adjustable valves should offer a firm lock to prevent drift.
- Flow and pressure ratings: Ensure the valve supports your system’s flow rate (GPM) and operating psi (PSI). Injectors should match the pump output to avoid under- or over-dosing chemicals.
- Chemical compatibility: If detergents or solvents are used, confirm the valve materials will resist solvent degradation and corrosion over time.
- Ease of maintenance: Look for replaceable seals, availability of spare parts, and straightforward disassembly for cleaning or replacement.
- Installation environment: Industrial settings may require rugged, sealed, and vibration-resistant designs. Home-use setups benefit from compact, easy-to-install options with clear adjustment controls.
- Warranty and support: Consider brands with accessible customer support and documented warranty terms to minimize downtime.
- System integration: For multi-component mixing, a three-port manifold or integrated assembly can reduce line fittings and improve consistency of chemical ratios.
- Safety features: Prefer valves with locking features or secure caps to prevent accidental changes during operation.
- Future upgrades: Choose modular components that can be swapped or upgraded as your soft wash system scales up.
