ASTM A216 WCB Flanged Lift Check Valve

An ASTM A216 WCB Flanged Lift Check Valve is an automatic valve that allows fluid to flow in one direction and closes when flow reverses. Unlike manually operated valves, it works through pipeline pressure difference without requiring external operation.
ASTM A216 WCB material provides a widely used carbon steel option for industrial valve applications. The flanged design allows convenient installation and maintenance in pipeline systems.

Design Features:

Pressure Range: Class 150 ~ 2500
Nominal Size Range: DN 50 ~ 900, NPS 2" ~ 36"
Connection: Flange (RF, FF, RTJ), Butt Welded (BW), Socket Welded (SW)
Lift type disc

Wall thickness: API 600
Pressure-temperature rating: ASME B16.34
Face-to-face dimensions for butt weld and flanged valves: ASME B16.10
Flange design: ASME B16.5
Butt welding design: ASME B16.25
All valves are designed to comply with the requirements of ASME B16.34, and the ASME as well as customers' requirements as applicable.

Body Material:

A216-WCB (Carbon Steel), A217-WC6 (1-1/4Cr-1/2Mo), A217-WC9 (2-1⁄4Cr–1Mo), A217-C5 (5Cr–1⁄2Mo), A217-C12 (9Cr–1Mo), A352-LCB (Carbon Steel), A352-LCC (Carbon Steel), A351-CF8M (18Cr–9Ni–2Mo), A351-CF3M (18Cr–9Ni–2Mo)

Quality Assurance (QA):

Every step from procurement through production, welding, assembly, testing, and packaging is in accordance with quality programs and procedures (ASME Section III manual and ISO 9001 manual).

Quality Control (QC):

The QC is responsible for all aspects of quality, from receiving of material to control of machining, welding, nondestructive examination, assembly, pressure testing, cleaning, painting, and packaging.

Pressure Testing:

Each valve is pressure tested in accordance with ASME B16.34, API 598, or special customers' requirements as applicable.

How Lift Check Valve Protects Your System

Reverse flow can cause equipment damage, pressure fluctuation and unstable operation. ASTM A216 WCB Flanged Lift Check Valves help protect pumps, compressors and pipeline equipment by automatically stopping backflow when the medium changes direction.
For industrial users, selecting a reliable check valve means reducing unexpected downtime and protecting valuable equipment investment.

Product Advantages

Automatic Operation: No manual operation or actuator is required; the valve responds according to pipeline flow conditions.
Fast Response: The disc movement design helps close the passage when reverse flow occurs.
WCB Carbon Steel Strength: Suitable for many industrial pressure applications requiring mechanical strength and durability.
Easy Maintenance: Flanged connection supports installation and maintenance convenience.

Manufacturing Process

Xiangzheng controls the complete manufacturing process from material preparation, machining, assembly and testing to final packing. For ASTM A216 WCB Flanged Lift Check Valves, machining accuracy and disc-seat matching are important factors affecting closing performance.
