Check Valves in Acrylic
acrylic_170This SmartTalk highlights check / pressure relief valves made in Acrylic, which is especially popular with customers working with applications that require:
  • Transparency
  • Easy bonding
  • Low temperatures
  • Mineral Oils
Pictured right, the Model #170 valve inserted into clear tubing allows complete visibility of flow. Acrylic is a great choice for devices working with lotions, creams, or ointments as they often contain mineral oil. Certain electronic systems also use mineral oil for their parts due to its non-conductive properties.

Beyond working well with mineral oils, Acrylic is an ideal choice for applications dealing with medicines or chemicals that need to remain at cold temperatures; Acrylic has a temperature compatibility range of -76°F to 194°F. Other notable properties of Acrylic include a very good tensile strength rating, good UV resistance, and the ability to be gamma radiated.


We offer this plastic in the following valves:

Featured Product: Model #111 and Model #118 - 1/4" Barbed Valves


Compact and easily inserted into 1/4" I.D. tubingModel #111 and Model #118 (its reverse flow option) are a great in-line check or pressure relief valve option for a wide variety of low pressure, low flow applications. 

model_111_ultemModel #111 (pictured right in Ultem®) and Model #118 are a beneficial design consideration because they eliminate the need for extra components (i.e. clamps). Additionally, as barbed valves, they work especially well to prevent leaks because the barbs grip tightly to the inside of soft tubing versus an external placement. 

Used for liquid or air, these valves are available at an opening pressure range from 0.09-20 PSI. They also come in several plastic body material options to include: Polypropylene, Nylon, Acrylic (pictured), Acetal, PVDF, Polycarbonate (pictured), Ultem® (pictured), and ABS. O-rings for both are Buna-N, EPDM, Viton®, Silicone, and Fluorosilicone.

To customize your own version of the Model #111 or Model #118 contact a Product and Application Specialist at (800) 338-0404 or sales@smartproducts.com.
