Product Overview

The Ultra Slim Wafer Check Valve is an extremely compact check valve designed for piping systems where space is limited. The valve's slim design (30-50% thinner than standard butt check valves) minimizes installation space and weight while maintaining excellent backflow protection.

Constructed of stainless steel, carbon steel or duplex steel, the valve is ideally suited for applications where traditional check valves are too large, such as pumping units in tight spaces, modular piping systems or retrofit projects. Its low resistance design ensures efficient flow with minimal pressure drop and is suitable for water, oil, gas and chemical media.

Product Characteristics

Ultra-thin: 30-50% less thick than standard butt check valves (e.g., DN50 is 25 mm thick vs. 40 mm standard thickness). Ideal for confined spaces or dense piping in skid mounted systems.

Lightweight design: Weight reduction of up to 40% reduces the structural load of pipe supports.

Low resistance flow path: optimized internal geometry minimizes turbulence and pressure losses (Cv values ≥ 1.2).

Quick closing mechanism: Spring assisted flap or double flap design ensures quick sealing and prevents water hammer.

Corrosion resistance: Stainless steel (316/316L) or duplex steel options for corrosive media (e.g. seawater, acidic media).

Compliance: Meets ASME B16.34, API 594 and ISO 17292.

Product Advantages

Space optimization: can be installed in ducts where space is limited.

Energy saving: low pressure drop to reduce pump workload.

Easy to retrofit: direct replacement of existing valves without the need for piping modifications.

Low maintenance: self-cleaning design and corrosion-resistant materials.
