Nozzle Check Valves

When choosing a Nozzle Check Valve, it is important to fully understand the features and their compatibility with the system flow parameters of your chosen application. Understanding the dynamic characteristics is extremely important and choosing the right valve design can have a huge impact on the service life of your component. A Non-Slam Nozzle Check Valve is designed to limit water hammer, a pressure surge that can arise in any pumping system, which undergoes an abrupt change in its rate of flow. Water hammer is a common problem with traditional check valves, however, a Non-Slam Nozzle Check Valve does not rely on flow reversal or gravity to close and instead uses an Axial Spring Solid Disc design or a Friction Free Multi-Spring Ring Disc design. As the spring force is optimised to suit the applications and the closing disc has a much shorter distance to travel than traditional valves, water hammer is reduced or completely prevented.

Nozzle-type check valves were specifically designed for hazardous systems where backflow was a concern. At MGA Controls, we can supply a wide range of Nozzle Check Valves, suited to critical service applications for the Water and Process Industries. Non-Slam Nozzle Check Valves minimise the damaging effects of water hammer whilst minimising pressure loss in piping systems. Manufactured from a range of hard-wearing materials, Nozzle Check Valves can be used for Gas Transmission, Power Generation, Chemical Processing, Hydrocarbon Processing and Water Transmission.
