Note: Ductile iron valve body,equipped with oil-resistant pressure gauge.
Product Overview:
Installed on the pump outlet pipelines of high-rise building water supply systems and other water supply systems to prevent medium backflow and to prevent water hammer and surge phenomena.This single valve combines the functions of an electric valve,a check valve,and a water hammer eliminator,effectively improving the safety and reliability of the water supply system.
Product Features:
1. Excellent water hammer elimination.The technical principles of slow-opening,quick-closing,and slow-closing are integrated to prevent water hammer during both pump startup and pump shutdown.
2. Easy operation.Simply operate the pump motor start/stop button,and the valve will automatically open and close in accordance with pump operating procedures.
3. Energy efficient.The valve body features a full-bore streamlined straight-through design,resulting in low pressure loss,large flow capacity,as well as compact size and light weight.
