Product Description

German Standard Cast Iron Wafer Check Valve

The German Standard Cast Iron Wafer Check Valve offers reliable one-way flow control with a compact, flangeless design. Featuring a durable cast iron body (GG25/EN-JS) and DIN-compliant construction, it prevents backflow efficiently while minimizing pressure loss in water, air, and non-corrosive media systems.

Specification

Key Features:

1.Wafer Design: Slim profile for easy installation between DIN/EN flanges (EN 1092-1) without additional bolts.
2.Soft-Seal Performance: EPDM or NBR sealing ensures zero leakage and silent closure under low-pressure conditions.
3.Robust Construction: Epoxy-coated cast iron body with stainless steel hinge pin (SS304/316) for corrosion resistance.
4.Automatic Operation: Swing disc design responds instantly to flow changes, requiring no manual intervention.
5.DIN Compliance: Meets DIN 3352 and EN 12266 standards for material quality and pressure testing.

Technical Specifications:

1.Size Range: DN50–DN600 (2"–24")
2.Pressure Rating: PN10/16
3.Temperature Range: -10°C to +120°C (dependent on seal material)
4.Installation: Horizontal or vertical (flow direction must match valve marking).

Advantages:

1.Low maintenance, lightweight, and cost-effective with long service life.
2.Eco-friendly design compliant with international engineering standards.
