Detail Information

Y Type Forged Check Valve

Body material: ASTM A105N
Nominal diameter: 3/4 Inch (DN20)
Nominal class: Class 800 LB (PN150)
End connection: NPT
Metal seat: 13cr
Design: API 602
Face to face: MFR, API 602
Test and inspection: API 598
Mode of operation: /

The forged steel check valve operates based on the medium's flow, automatically opening and closing the valve disc to prevent reverse flow. Also known as a check valve or one-way valve, it ensures fluid flows in one direction. The body guide ensures alignment of the seat and disc. When closed, flow pressure lifts the disc off the seat, allowing fluid to pass through the valve.

Forged Steel Lift Check Valve-Features

1. The valve disc moves vertically, connected to the upper chamber via a connecting pipe. This design reduces impact and vibration, enabling the disc to reach its full stroke.
2. The Y-shaped valve body minimizes resistance, with hard alloy deposited on the guide rib. Stainless steel is used for the guide sleeve, ensuring flexible valve cover operation.
3. Pressure self-tightening sealing ensures reliable sealing.
4. Both the valve disc and seat feature cobalt matrix alloy welding on their sealing surfaces, offering high hardness, corrosion resistance, scratch resistance, and durability.
