Product Overview
The Grooved Swing Check Valve is engineered for efficient backflow prevention in a wide range of applications, particularly in fire protection systems. Featuring grooved end connections, this valve allows for fast installation and easy maintenance without sacrificing reliability. It is designed to provide a low-pressure drop and is suitable for both horizontal and vertical (upward flow) installations.
Certified for Global Standards
This swing check valve is UL Listed, FM Approved, VdS Certified, and LPCB Approved, making it ideal for use in international projects where compliance and safety are critical. It supports working pressures up to 300 psi (UL/FM) and 362 psi (VdS/LPCB), meeting the highest performance standards in the industry.
Durable Materials and Construction
Constructed from high-strength ductile iron and coated with red, lead-free epoxy, the valve body ensures long-term durability and corrosion resistance. The disc is also made from ductile iron and lined with EPDM rubber, delivering a bubble-tight seal even in demanding environments. Internal components such as the hinge pin and seat are made from stainless steel or bronze for maximum reliability.
Ideal Applications
The grooved swing check valve is commonly used in fire sprinkler systems, HVAC systems, and other water supply networks that require reliable backflow control. Its compact, grooved-end design allows for rapid integration into new or existing piping layouts, saving labor and downtime.
