Forged steel check valve is to rely on the flow of the medium itself and automatically open and close the valve disc, used to prevent the reverse flow of medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.  The body guide ensures alignment of the seat and disc when the piston check valve closes, and the flow pressure will force the disc to lift off the seat and allow fluid to pass through the valve.

Y Type Forged Steel Check Valve - Features

1. The valve disc moves up and down. The connecting pipe connects the upper chamber with the valve outlet. When the valve disc rises and falls, it reduces impact and vibration, and allows the disc to reach its full stroke;
2. The valve body is Y-shaped with low resistance, and hard alloy is deposited on the guide rib. The guide sleeve is made of stainless steel material, and the valve cover operates flexibly;
3. Adopting pressure self tightening sealing, reliable sealing;
4. The sealing surfaces of the valve disc and valve seat are both made of cobalt matrix alloy by welding, with high hardness, corrosion resistance, scratch resistance, and durability.
