Michael Goltz, superintendent of the Mt. Horeb, Wis., Wastewater Treatment Plant, settled on the Val-Matic Swing Check Valve because it specifically addressed the slamming and clogging problems exhibited by the previous swing check valves.

New Valves Maintain Piping System Integrity at High Temperatures, Provide Increased Chemical Reaction Time   Water & Wastes Digest March 2003
PVDF (polyvinylidene fluoride), a flouroplastic, is the material of choice for high purity water and chemical applications due to its excellent purity, temperature, surface and strength characteristics. The material expands as the temperature increases. George Fischer, Inc. designed the first SYGEF® PVDF High Temperature Resistant (HTR) diaphragm valve; it incorporates secondary sealing components manufactured from high purity TFM within the valve body to absorb the different expansion characteristics of the valve materials.
