Vertical check valve
The Vertical Check Valve is specifically designed for installation in vertical pipelines where fluid flows upward. Utilizing gravity and fluid pressure for automatic operation, it effectively prevents backflow, protects pumps and equipment, and minimizes water hammer effects. Its compact design and durable construction ensure reliable performance in industrial and municipal applications.
Vertical check valve
The Vertical Check Valve is an automatic non-return valve engineered for vertical piping systems. The valve disc lifts when fluid flows upward and automatically closes when flow stops or reverses, preventing backflow and safeguarding pumps, compressors, and other critical equipment.
Manufactured from high-quality cast steel, stainless steel, carbon steel, or ductile iron, the valve provides excellent corrosion resistance, pressure resistance, and sealing performance. Its compact design allows easy installation in limited spaces while ensuring efficient fluid flow and minimal pressure drop.
Our Vertical Check Valves are manufactured and tested according to international standards:
