Product Description

German standard stainless steel monolithic check valve

The DIN Standard Stainless Steel Wafer-Type Single Disc Check Valve ensures reliable prevention of reverse flow in pipelines carrying water, steam, compressed air, and non-viscous liquids. Compliant with DIN 3356 and EN 12334 standards, its compact, lightweight design suits space-constrained installations while maintaining high durability in corrosive or high-temperature environments.

Specification

Key Features:

1.Premium Material: Body and disc made of AISI 304/316 stainless steel for exceptional corrosion resistance and longevity under temperatures from -196°C to +400°C (depending on seals).
2.Space-Saving Design: Wafer-type structure minimizes weight and installation space, compatible with DIN/EN-compliant flanges.
3.Zero-Leakage Performance: Spring-assisted single disc with NBR/EPDM/PTFE sealing ensures fast, tight closure even at low pressure differentials.
4.Bidirectional Fit: Suitable for horizontal or vertical mounting with no directional restrictions.

Technical Specifications:

1.Pressure Rating: PN10–PN40 (1.0–4.0 MPa)
2.Size Range: DN15–DN400 (½"–16")
3.Connection: Wafer-type (DIN/EN 1092 flange compatible)
4.Testing Standards: EN 12266-1 (leakage), ISO 5208 (pressure).

Advantages:

1.Low pressure drop due to streamlined flow design.
2.Maintenance-free operation with no external actuators.
3.Cost-effective solution for preventing water hammer and backflow.

Applications:

Ideal for chemical processing, water treatment, HVAC, food & beverage, and oil/gas systems requiring strict adherence to DIN standards.
