Flomatic Unveils Model 745SC – 3″ AWWA C508 Swing Check Valve, AIS Compliant & Spring Assisted Closure

April 22nd, 2024 Glens Falls, NY – Flomatic Valves, a leading provider of water control solutions, is delighted to unveil the new Model 745SC – 3″ swing check valve. This valve is designed to meet the requirements of AWWA Standard C508 and complies with American Iron & Steel (AIS) provisions, ensuring superior performance, reliability, and versatility.

The Model 745SC, Surge-Stopper®, is a precision-engineered swing check valve incorporating a rapid closure spring in conjunction with a resilient flapper hinge, resulting in reduced disc closing time. The valve is constructed using a fusion-bonded, epoxy-coated ductile iron (A536 65-45-12) body, Buna-N flapper (EPDM optional), and stainless steel spring. The stainless steel spring acts in conjunction with a 45-degree seating surface to minimize disc travel, and rapidly close the valve and prevent slamming during rapid flow reversals.

The resilient seating design features a replaceable one piece molded flapper consisting of a reinforced flexible hinge and steel flapper disc encapsulated in Buna-N rubber. The molded seating surface of the disc utilizes a raised rib seal providing a line contact with the mating machined seat surface. These features combined provides bubble-tight sealing under low pressure and is suitable for vacuum service.

This valve is designed for municipal and industrial water and wastewater applications by fully complying with ANSI/AWWA Standard C508 full waterway design. The model 745SC can be supplied with a Back Flush Device, Position Indicator, and/or Limit Switch for enhanced versatility. This valve is suitable for installation in both horizontal and vertical pipelines. For ease of maintenance, the internal resilient flapper and rapid closure spring are both accessible and field replaceable through the valve cover access port, without removing the valve from the pipeline.

Ductile iron is used to construct the body and cover to provide greater durability. The ductile iron is coated with NSF/ANSI 61 powder epoxy coating (interior and exterior). The AIS compliant design utilizes components produced in the USA with US sourced materials.

Flomatic Corporation is renowned for its commitment to quality and environmental sustainability. As evidence of this dedication, Flomatic holds ISO 9001 and 14001 certifications, ensuring stringent quality management and environmentally responsible practices. The Model 745SC AWWA C508 swing check valve is proudly manufactured at the company’s headquarters in Glens Falls, NY.
