Silencing Slow-Close Check Valve for Water and Sewage Applications

SILENCING SLOWLY-CLOSING CHECK VALVE
Product Model: HH49X

Product Overview

The HH49X Silencing Slowly-Closing Check Valve is designed to prevent backflow and minimize noise and shock during closure. It combines the features of a check valve and a throttle valve, providing slow closure to reduce water hammer and protect pipeline systems. The valve is suitable for water supply, drainage, fire protection, HVAC, and industrial applications.

Key Features

  1. Backflow Prevention
    • Automatic Operation: Opens and closes with media flow to prevent reverse flow.
    • Water Hammer Prevention: Slow closure reduces pressure surges and protects pipelines.
  2. Noise Reduction
    • Innovative Design: Features rubber sleeves and noise-reducing components to absorb vibrations and reduce noise.
    • Quiet Operation: Ensures minimal noise in residential, commercial, and industrial applications.
  3. Durable Construction
    • High-Quality Materials: Constructed from corrosion-resistant materials for long service life.
    • Reliable Sealing: Ensures tight closure and prevents leakage.
  4. Efficient Design
    • Low Resistance: Streamlined design minimizes pressure drop and energy loss.
    • Versatile Installation: Suitable for both horizontal and vertical installations.
