Swing Check Valve (ANSI)

In industrial piping systems, the ANSI swing check valve is designed to reliably prevent reverse flow, while offering low pressure drop and dependable tightness. Manufactured in accordance with ANSI/ASME standards and available in a wide range of materials, it integrates seamlessly into your process lines.

What Is an ANSI Standard CS Swing Check Valve and How Does It Work?

Also known as a swing check valve, this valve operates on the principle of a disc that swings open in the direction of flow and swings back onto the seat when reverse flow starts. This simple yet effective design minimizes backflow risk in water, steam, gas and process media. Low turbulence, a large flow cross-section and optional metal or soft seats provide both energy efficiency and long service life.

Standards and Compliance (ANSI/ASME)

The ANSI Standard CS Swing Check Valve is available in ANSI/ASME Class 150/300/600 pressure ratings and is typically compliant with:

ASME B16.10 – Face-to-face dimensions

ASME B16.5 – Flanged ends

ASME B16.34 – Pressure–temperature ratings

Each valve is factory-tested according to API 598 leakage test requirements, ensuring verified tightness and reliable performance. This reduces the risk of unexpected reverse flow and water hammer in critical processes.

Engineering Selection Support

Customers can provide drawings, old valve photos or technical specifications. Xiangzheng helps confirm size, pressure, medium, connection and application conditions before production.

Manufacturing Process

The production process includes material preparation, machining, assembly, inspection, surface treatment and packing. Controlled manufacturing helps maintain consistent quality for different orders.

Quality Inspection System

Every valve is inspected before shipment. Inspection includes dimension inspection, wall thickness inspection, hardness testing, PMI material verification, visual inspection and pressure testing. Quality photos and records can be provided according to customer requirements.

Packaging and Delivery

Before shipment, valves are protected with export packing methods. Flange faces, painted surfaces and important components are protected during transportation. Wooden cases, packing photos and shipment details can be provided.

After-Sales Guarantee

If customers find any product problem after receiving goods, they can send photos or videos for verification. If the issue is confirmed to be caused by Xiangzheng manufacturing, we will reproduce the correct products free of charge. The incorrect products do not need to be returned.
