Applications

Overview & Design Standards
Definition:A check valve with a hinged disc that swings around a horizontal shaft to prevent backflow, compliant with German engineering standards.
Key Standards:Design: DIN EN 12266-1 (valve testing), DIN 3202 K1 (swing check valve structure)
Materials: DIN EN 10213 (cast steel), DIN 17440 (stainless steel)
Flange connections: DIN EN 1092-1 (flange standards), PN10/PN16/PN25/PN40 pressure classe

Structural Characteristics
Main Components:
Valve Body:Cast steel (GG25/GGG40) or stainless steel (1.4301/1.4408) for corrosion resistance.
Disc:Hinged at the top or side, often with a rubber (EPDM/NBR) or metal (stainless steel/stellite) sealing surface.
Hinge Mechanism:Chrome-plated steel shaft for wear resistance, with bushings (bronze or PTFE) to reduce friction.
Structural Types:
Full-Bore Design:Minimal flow resistance (Cv value ≈90–110 for DN100), suitable for high-flow systems.
Wafer Type (DIN 3202 K1):Clamped between flanges, length ~150mm for DN100 (shorter than flanged types).
Flanged Type (DIN EN 1092-1):Compatible with PN-series flanges, suitable for high-pressure applications (PN40 max).

After Sales Service

Standard Warranty: 12 months or 2,000 operating hours (whichever comes first).
Global Support: 24/7 technical assistance and spare parts supply.
