ERK Tilting Check Valve
The ERK tilting disc check valve is the result of more than 50 years of experience in building and use of tilting-disc check valves.
CHARACTERISTICS
Low head loss is ensured by the double-offset free-swinging disc, key component of the ERK. The disc is freely oscillating and has a flowfacilitating design with its double eccentricity supports.
Maximum crossing section reached by a two-part shaft.
Maintenance-free valve – Thanks to the construction of the shafts, self-lubricating friction bearings and maintenance-free seals from the shaft.
Perfect sealing – Provided by a rolled up, solid body seat ring made of stainless steel, and a disc seat ring which is additionally provided with a resilient precision seal.
Low operating torque – Thanks to the double eccentric design, ensuring also a low wear and tear of the disc seal.
Protection against corrosion – Brought by the choice of stainless steel for the shafts, the body seat and the disc seat.
Shafts protruding on both sides to facilitate individual mounting of the weight-loaded lever.
