Features & Benefits
90-Degree Angle Saves Elbow
Integral 90-degree angle body eliminates separate elbow fitting, reducing weld joints, pressure loss, and piping footprint by one fitting.
Combined Stop and Check
Single valve provides both manual handwheel isolation and automatic disc check action, saving space and maintenance points.
Guided Disc Stability
Body guide ribs and disc guide wings maintain axial alignment, preventing side loading and vibration-induced seat damage.
Rapid Closure Spring Option
Optional SS304 compression spring accelerates disc seating on flow reversal, reducing backflow and water hammer in pump discharge.
IBR Certified Option
Design, material, and testing certified to Indian Boiler Regulations for boiler feed and steam heater applications.
