Check valve is easy to install, comes in sizes up to 12 inches
Offering expanded application versatility, GF Piping Systems introduces the Type 369 Wafer Check Valve, the company’s first check valve to be offered in sizes as large as 12 inches. This feature, combined with its simple installation ability, unique spring option for horizontal mounting, and excellent flow characteristics, make it an ideal check valve solution for a variety of applications. Suitable uses include water and wastewater treatment, aquatics, chemical processing, municipalities, and water parks.

Check valves, used to allow flow in one direction, typically require glue or tools for installation. GF Piping’s Type 369 Check Valve eliminates these requirements – the valve is simply inserted between two standard ANSI or ISO/DIN flanges, making for easy installation or removal in the field. Centering eyelets provide easy fitting, adding to installation simplicity.

For applications requiring horizontal mounting rather than standard vertical mounting where gravity is present, the Type 369 provides a unique solution. Designed with a spring option available in either 316 SS or Hastelloy C, this feature provides the unique functionality of being able to operate in the horizontal position, offering increased application flexibility. For standard vertical mounting, the option need not be ordered. “Up until now, we have only had a 3-inch check valve solution,” the company states. “With the new Type 369, our capabilities are vastly expanded with a selection as low as 1-1/2 inches and as high as 12 inches. Additionally, the valve’s spring loaded option make it unique to the market. Unlike most check valves that must be installed vertically, this feature allows the valve to be installed horizontally – an important advantage in certain applications.” The Type 369 also offers significantly improved flow characteristics when compared to ball-type check valves. With ball check valves, liquid circulates around the ball during opening or closing, causing flow restriction and pressure drop. In some applications, this might be a critical disadvantage. The Type 369 wafer check design incorporates a swinging flap-type door that is less restrictive than a ball check style, providing enhanced flow characteristics.

The Type 369 Wafer Check Valve is available in sizes 1-1/2-inches to 12 inches and is available with a PVC body and EPDM or FPM seals. A specially designed sealing Q ring makes it compatible with flat or serrated flanges. Competitively priced, the Type 369 Check Valve meets ANSI and ISO/DIN standards.
