Product description

Highlights at a glance

  • The HC42X/DRVZ silent check valve is mainly composed of main components such as valve body, valve seat, guide body, valve disc, bearing, and spring. The internal flow channel adopts streamlined design, with minimal pressure loss. The opening and closing stroke of the valve disc is very short, and it can be quickly closed when the pump is stopped to prevent huge water hammer sound, with the characteristic of silent closing. This valve is mainly used for water supply and drainage, fire protection, and HVAC systems. It can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump.
  • Silent quick closing, effective water hammer elimination Short stroke disc with spring-driven rapid shut-off avoids loud water hammer noise, fully protects water pumps and pipeline systems from backflow damage.
  • Streamlined internal flow channel, ultra-low pressure loss Optimized streamlined structure greatly reduces fluid resistance, cuts pipeline energy consumption for better energy-saving performance.
  • Stable & durable mechanical structure Consists of valve body, valve seat, guide body, disc, bearing and spring, precise guiding ensures flexible, stable opening and closing with long service life.
  • Wide range of application scenarios Perfectly installed at pump outlets, widely used in water supply & drainage, fire protection, HVAC systems for industrial and commercial projects.
