Hosco Restrictor, Externally Adjustable, 3/8 NPS (F) x 1/4 NPS (M) (RYA-4)

Hosco Stainless Steel Restrictors provide reliable, long life fluid flow control to an applicator. The family of products consists of recirculating and non-circulating versions that can be internally set (tamperproof) or externally adjusted even while dispensing. The long tapered needle design of the restrictors provides fine flowrate adjustments from complete shut off to over 1000 cc/ min (depending on pressure and viscosity). Settings are repeatable from restrictor to restrictor station so set up is relatively easy. The internally set styles may require the RAB-6 Tool to provide initial set point adjustment while the restrictor is “on line”. The externally adjusted versions require an Allen wrench for adjustment which is included with the restrictor.

Features and Benefits

SST Construction

• Long life

• Compatible with all coatings and adhesive materials known

Compact Design

• Allows spray operators to maneuver the spray gun into small areas or tight spaces much easier than alternatives

• Much smaller and lighter than regulator based alternatives

Multiple Configurations

• Tamperproof or externally adjustable versions

• Circulating or non-circulating versions

• In-line or 45 degree hose connection versions on circulating versions to keep hoses away from the product being coated

Low Sheer Design

• 0.350” smooth bore passageways in circulating versions protect the coating from excessive shear during operation and minimize pressure loss of the recirculating function

Highest ROI Flow Control Device

• Hosco Restrictors are generally 1/3 the cost of older regulator versions, and last easily 10X longer between service events or replacement
