​ERK TILTING DISC CHECK VALVE

​​A key component of the ERHARD ERK tilting disc check valve is a valve disc which has a freely oscillating, flow-facilitating design with double eccentricity support. The shafts are in maintenance-free, self-lubricating friction bearings, and the shaft has maintenance-free seals. A rolled up, solid body seat ring made of stainless steel, and a disc seat ring which is additionally provided with an elastic fine seal, provide perfect sealing

The ERHARD ERK check  valve is designed for medium water, from DN600 also suitable for sewage, and is designed in a short face-to-face length. With nominal diameters ranging from DN150 to DN1000 and pressure ratings ranging from PN10 to PN25, as well as numerous options, the ERHARD ERK tilting-disc check valve provides a solution that can be individually adapted, even for special applications. For accident prevention in the swing area of the lever a protective cage is available. For an legal back-flow, for delayed smooth closing  or opening and to avoid pressure shock  a damping device, weight-loaded hydraulic actuator, is available. To improve  the economics of the plant,  a pneumatic fill opening device is available too.
