Descripción
The HR FLUM VALVES HR-30 cast iron hydraulic valve is a hydraulic diaphragm valve, with a basic opening and closing operation due to the pressure exerted by the water in the pipeline.
Threaded connection: DN 50 – 2″
FEATURES
- Flanges according to ISO 7005-2.
- Membranes and springs PN16, horizontal closure.
- Easy access to the control chamber without the need to remove the valve from the pipeline.
- Teflon coated screws.
- Optimum operation both in horizontal and vertical position, thanks to its ribs interiors that prevent lateral and longitudinal deformation of the membrane, maintaining the
membrane without deformation. - Simple and robust design.
- Low pressure drops thanks to the design of the body and the membrane
MATERIALS
- Body and cover: GGG ductile iron, with 250 micron epoxy-polyester paint coating.
thickness - Spring: Stainless steel
- Membrane: Natural rubber reinforced with nylon fabric
FUNCTIONING:
The valve opens or closes hydraulically depending on the pressure applied to the top of the diaphragm:
- If the applied pressure is equal to or greater than the inlet pressure, the valve automatically closes.
- Totally watertight.
- If the applied pressure is lower than the input pressure, the valve opens completely.
- By means of the hydraulic valve we can regulate the pressure or the flow in a pipe, varying the volume of water in the upper part of the diaphragm.
