Product description<\/span><\/span><\/span><\/h3>\n

Some control pumps, such as the Parker PV axial piston pumps, require a minimum pressure of 20 bar to function properly.<\/span><\/span> This can be imposed by a preload valve.<\/span><\/span> The Wessel preload valve is available with connection sizes from \u00be” to 1 1\/4″.<\/span><\/span> It is flanged directly onto the pump connection as an intermediate block.<\/span><\/span> In the valve, the flow is preloaded by a valve cone.<\/span><\/span> The preload pressure is applied constantly and loss-free by a pressure reducing valve.<\/span><\/span> The valve is usually set to 20 bar.<\/span><\/span> If the pump pressure exceeds the preload pressure, the valve opens completely and the volume flow is passed on with almost no loss.<\/span><\/span> Two ports P1 and MP are available upstream of the preload valve, from which, for example, a pilot pressure supply could be tapped.<\/span><\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
