The axial check valve type RD100 \u2013 also referred to as a nozzle check valve \u2013 prevents backflow in piping systems with minimal pressure differential. Thanks to the axial flow path and the spring-loaded closure element, the valve closes within fractions of a second, before full backflow can occur. The result: effective protection against pressure surges (water hammer) with the lowest possible flow resistance.<\/p>\n\n\n\n
In a nozzle check valve, the closure element moves axially along the flow axis \u2013 not sideways like a swing check valve or vertically like a lift check valve. The short closing stroke of the spring-loaded disc enables an extremely fast response to pressure reversal. At the same time, the flow-optimised conical shape ensures low-turbulence flow with a low resistance coefficient.<\/p>\n\n\n\n
Compared to conventional check valves<\/a> or wafer check valves<\/a>, the axial check valve offers significantly lower pressure loss and quiet, surge-free operation.<\/p>\n\n\n\n The axial check valve RD100 is constructed in the standard version with the following materials:<\/p>\n\n\n\n Available nominal sizes: DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400 and DN500. Flange connection according to PN10, PN16, PN25 and ANSI 150 \u2013 face-to-face dimension according to DIN EN 558<\/a>.<\/p>\n\n\n\n For more demanding operating conditions, the RD100 is also available in alternative material combinations:<\/p>\n\n\n\n The right material selection depends on the medium, temperature and pressure range. Fergo advises on selecting the optimal configuration.<\/p>\n\n\n\n Axial check valves are suitable wherever fast, surge-free closing and low pressure loss are critical. Typical applications for the RD100:<\/p>\n\n\n\n Especially in high-pressure pump systems, nozzle check valves offer a longer service life and better dynamic performance than conventional swing or ball check valves. All versions are available for online purchase<\/a> directly from Fergo.<\/p>\n\n\n\n The axial check valve RD100 can be installed in various mounting positions:<\/p>\n\n\n\n For vertical or inclined installation, the integrated spring supports reliable closing even against gravity. For clean media, an upstream strainer<\/a> is additionally recommended to keep foreign particles out of the system and increase the service life of the valve.<\/p>\n","protected":false},"excerpt":{"rendered":" Axial Check Valve \u2013 Fast backflow stop with lowest pressure loss The axial check valve type RD100 \u2013 also referred to as a nozzle check valve \u2013 prevents backflow in piping systems with minimal pressure differential.

Axial Check Valves made of GG25<\/h2>\nAxial check valves are special valves that allow the flow of liquids or gases in only one direction, preventing backflow. Due to their axial design, they offer low pressure loss, fast response time, and high reliability. These valves are robustly built, often from materials such as stainless steel, and are used in the oil and gas industry, power plants, and water treatment. They are known for their efficiency and ease of maintenance, but can be more expensive than conventional check valves. \n
