Kynar Body
The body of our check valves is made in PVDF, or Kynar (a registered trademark of Atochem North America Inc.). Kynar has good general chemical resistance to hot acids halogens, alcohols, aromatics, oxidants, mild bases and aliphatics. Kynar is also ultraviolet resistant, fungus resistant, abrasion resistant and chloride resistant.
Free Floating Viton Diaphragms
Free floating diaphragms allow the check valve to be used in any position with little compromise in function. The free floating method assures a quick response to changes in pressure and flow. Diaphragms have been tested to pressures up to 150 PSI and as low as 1 PSI. They are made in Viton.
Superior Barb Design
Our Kynar check valves are designed for exacting instrument applications and feature a newly designed barb without a parting line. No parting line and a sharp barb eliminate any possibility of flash or mold mismatch that may provide a leak path causing the fitting to fail. Unlike multiple barb fittings that can allow the tubing to bridge between the barbs, our single barb design lets the tubing relax behind the sharp barb to ensure a secure leakproof seal.
Quality Control
Our check valves are meticulously molded using the newest technology to provide instrument quality fittings for demanding laboratory applications. After molding, the check valves are assembled using a non toxic technique without the use of foreign materials. Our check valves are 100% inspected over sorting tables as final measure prior to packaging. |
