Product Overview

The Mild Steel Wafer Check Valve with NBR Seat is a compact, lightweight, and high-performance non-return valve designed to prevent reverse flow in pipelines. Manufactured in accordance with API 6D standards, this wafer-type check valve is widely used in industrial fluid handling systems across India.

Engineered for durability and performance, this valve is suitable for water, oil, air, and non-aggressive fluids. Its compact wafer-type construction allows installation between flanges, reducing space requirements and overall pipeline cost.

This product is closely associated with industrial flow control components such as:

• Dual Plate Check Valve
• Non Return Valve (NRV)
• Butterfly Valve
• Cast Iron Wafer Check Valve
• MS Flanged Check Valve

Indian industries prefer wafer-type check valves due to ease of installation, lower weight, and economical pricing compared to full-body flanged designs.

What is an API 6D Wafer Check Valve?

An API 6D check valve is designed as per stringent pipeline standards applicable to oil & gas and high-integrity industrial pipelines. API 6D ensures:

• Robust pressure design
• Reliable backflow prevention
• Standardized testing procedures
• Durable construction for industrial usage

When combined with NBR seating, the valve provides tight shut-off and excellent sealing performance in water and oil-based applications.

Why Choose Mild Steel Body?

Mild Steel (MS) body offers:

• High mechanical strength
• Good weldability
• Cost-effective pricing compared to stainless steel
• Suitable for coated industrial applications
• Better impact resistance compared to cast iron

For Indian infrastructure and industrial projects, MS wafer check valves provide an ideal balance between performance and affordability.
