GF introduces the NeoFlow Pressure Sustaining Valve

The Swiss flow solutions provider has extended its range of pressure regulating valves for water distribution. The lightweight and compact NeoFlow Pressure Sustaining Valve is designed to protect upstream networks against insufficient or even negative pressure. 

While excessive pressure can cause serious damage in water networks, the same is true for insufficient pressure, as backflow and sudden pressure drops can increase contamination risks and cause water hammers. In addition, negative pressure can create a vacuum that may lead to reverse leakages, damage to pipe joints, or even pipe implosions.

With the introduction of the NeoFlow Pressure Sustaining Valve (PSV), GF is offering an additional tool to maintain the pressure balance in water networks. Thanks to an axial flow construction, it does not require an actuator stem or diaphragm and is less prone to cavitation damage. Combined with a polymer valve body, this makes the NeoFlow PSV nine times lighter and five times more compact than metal alternatives. Customers therefore benefit from an up to 40% faster installation which reduces costs and saves valuable time. Available for pipe dimensions from DN50 to DN300 and pressures up to 16 bar, the valve can also be tailored to meet individual needs. The integrated pilot valve ensures continuous regulation of the preselected outlet pressure and allows parameters such as flow and water quality to be monitored and controlled with additional equipment.

Sven Merath, Product Manager Pressure Management at GF, comments on the launch: “Ever since the inception of the NeoFlow product range, it has been our mission to bring balance to water networks and combat non-revenue water. The NeoFlow Pressure Sustaining Valve achieves outstanding pressure control that protects networks and extends their service life, while simultaneously outperforming metal valves in areas such as weight, handling, and durability.”

In addition to the PSV, the NeoFlow line-up also includes a pressure reducing valve and a dual setpoint pressure reducing valve. Both valve types are designed to prevent over-pressurized pipes by ensuring an accurate and stable flow, as well as increased flow capacity. Furthermore, all NeoFlow pressure regulating valves can be flexibly adapted to customer applications - from reservoir level control to fully automated valves.
