ERHARD is a company of Datasheet
The economical solution for high pressures and high flow rates Especially with high flow velocities up to 5 m/s and pressure ratings up to PN 4, the offers the ideal and economical solution for manifold applications in the water and sewage sector. Thanks to its design, it has a very low resistance coefficient compared to other types of valves when in the open position. The valve resistance coefficient has a strong impact on the energy inputs of pumps in closed pipe systems. In direct comparison between a butterfly valve and an ERHARD Ball valve it becomes evident that the necessary purchase costs will mostly amortize already in the first years of usage. We will be happy to calculate the specific energy savings for your specific application. More properties: Low construction height and full straight-through bore The ball plug of simple and solid moulded design is eccentrically supported Thanks to the soft transitions, no non-turbulent flow conditions are necessary upstream or downstream of the valve The profile ring is in open position outside the flow path Insensitive to dirt and scrapable The robust sealing part seals on both sides It is insensitive to deposits and guarantees absolute leak tightness and high deformation resistance Even after long periods without operating: smoothly and tight. Standard mounted with slider-crank mechanism. The movement kinematics is almost exactly the curve-characteristic of the valve. Pressure surges can be avoided. Epoxy coating for optimum corrosion protection Wide range of accessories: spindle extensions, with electro-actuator, with weight loaded hydraulic actautor Operating instructions BA49E_KH_SP-SKG_Getr_ HR_DN8-2 BA49E8_KH_SP-SKG_Getr_ EA_DN8-2 2
