Description

Forged Steel Check Valve – Overview

The forged steel check valve is a compact, high-strength non-return valve designed to prevent reverse flow in pipelines. Built from forged steel for exceptional pressure and temperature resistance, it operates automatically—opening under forward flow and closing to prevent backflow—protecting pumps, compressors, and other equipment.

Key Design Features

Forged Steel Body
Available in ASTM A105, A182 F11/F22, F304, F316, or other alloy steels, ensuring superior mechanical strength and corrosion resistance.
End Connections
- Flanged Ends – Compliant with ASME B16.5 standards for secure bolted connections.
- Socket Welding (SW) or Threaded (NPT/BSP) – For compact installations and high-pressure service.
Pressure Class
Typically offered in ASME Class 800 / 1500 / 2500, suitable for demanding service conditions.
Sealing Options
Metal-to-metal hard-faced seat or soft-seated designs depending on media and operating conditions.
Flow Direction Control
Clearly marked with flow arrows to ensure correct installation.

Applications

Oil & Gas – Prevents reverse flow in crude oil, natural gas, and refined product pipelines.
Chemical Processing – Handles corrosive or hazardous process fluids.
Power Generation – Suitable for steam and condensate systems.
General Industry – For liquids, gases, and steam where backflow prevention is essential.

Advantages

High Durability – Forged steel construction ensures long service life in high-pressure environments.
Compact Design – Easy to install in restricted spaces.
Reliable Performance – Automatic operation with minimal maintenance requirements.
Versatile Connections – Multiple end connection options for integration into various pipeline systems.
