Product Description
DRVZ Vertical Silent Check Valve
Cast steel and stainless steel construction for reliable backflow prevention in industrial fluid systems. Designed for minimal noise and water hammer reduction.
Product Overview
The H42H series vertical check valve prevents medium backflow and provides reliable check functionality. The valve automatically opens when inlet pressure exceeds outlet pressure, and closes automatically to prevent reverse flow when outlet pressure is higher.

Key Features
- Streamlined valve body design reduces fluid resistance by minimizing sharp bends and protrusions
- Conical valve disc design reduces fluid resistance and minimizes noise from turbulence
- Short closing stroke (1/4 of nominal diameter) reduces valve closing time and water hammer generation
- Spring-assisted closing mechanism accelerates disc closure and further reduces water hammer
- Flexible installation - suitable for both horizontal and vertical pipeline configurations
Installation Options
Can be installed horizontally or vertically. Spring is required for horizontal pipeline installation, while vertical installation utilizes disc weight and medium pressure for automatic closure.
