Product Overview

The Silent Clamp Check Valve is a sanitary, low-noise check valve designed for food and beverage, pharmaceutical and bioprocessing applications that require quiet operation and easy maintenance. The valve features a silent closing mechanism and triple-clamp connection that minimizes water-strike noise while ensuring a quick seal to prevent backflow.

Constructed of 316L stainless steel with an electropolished surface (Ra ≤ 0.5 μm), the valve meets stringent sanitation standards and resists corrosion in CIP (clean-in-place) and SIP (sterilization-in-place) systems. Its compact design and clamp connections allow for quick installation and sterilization, making it ideal for high-purity fluid handling.

Main characteristics

Silent Closing Mechanism: Spring-assisted flap with hydraulic damper ensures smooth, noiseless closure and reduces the water hammer effect by up to 701 TP3 T. Operating noise is less than 50 dB(A) (80 dB(A) for standard check valves).

Sanitary Clamp Connections: Triple clamp (cloverleaf) fittings meet 3A, EHEDG and FDA standards for sanitary applications. Easily disassembled for cleaning and inspection without tools.

SANITARY DESIGN: All 316L stainless steel construction with electropolished or mirror polished surface. No dead corners or crevices, effectively preventing the growth of bacteria.

Low resistance to flow: optimized flow path with very low pressure drop (Cv ≥ 1.5 at DN50). Suitable for high-purity liquids such as dairy products, beverages and pharmaceuticals.

Compliance: Meets 3A sanitary standards, EHEDG, ASME BPE and ISO 2852.

Product Advantages

Noise reduction: Designed to operate at less than 50 dB(A), ideal for noise-sensitive environments.

Easy to clean: Clamp connections and smooth surfaces simplify the CIP/SIP process.

Zero Contamination: Hygienic design prevents product retention and microbial growth.

QUICK INSTALLATION: Triple clamp ends can be assembled quickly without welding or threading.
