KSB Forged Steel Non-Return Valve ISO 15761 / BS 5352 | Awal Valve

KSB Forged Steel Non-Return Valve with Spring-Loaded Disc (ISO 15761 / BS 5352 & ASME B16.34)

Introduction

In high-pressure and high-temperature fluid handling systems, preventing reverse flow is vital for protecting pumps, compressors, and upstream piping components from backpressure damage and severe hydraulic shocks. The KSB forged steel non-return valve with spring-loaded disc is engineered specifically to deliver fast, positive closing under demanding process conditions. Manufactured in strict compliance with international manufacturing standards such as ISO 15761, BS 5352, and ASME B16.34, this non-return valve (check valve) provides compact, robust performance across power generation, steam generation, refining, and general industrial process pipelines.

Product Overview

The KSB forged steel non-return valve utilizes a compact forged body construction, eliminating the internal porosities and micro-voids associated with standard sand castings. Designed as a lift-check non-return valve with an integrated spring-loaded disc, the internal coil spring exerts mechanical force on the disc to ensure rapid seating as soon as forward flow velocity drops to zero.

This spring-assisted design allows the valve to operate reliably in both horizontal and vertical piping runs regardless of gravity orientation. Constructed with a bolted bonnet for Class 800 designs or a welded bonnet design for higher pressure ratings (such as Class 1500 and Class 2500), the unit provides high mechanical integrity, tight shut-off, and minimum pressure drop across the internal flow passage.

Technical Specifications

The following table outlines verified technical parameters and design characteristics based on official technical standards and product documentation:

Note: Specific material test certificates (MTC), IBR approvals, and temperature-pressure derating curves must be confirmed against the individual KSB datasheet for exact product codes.

Key Features

• Spring-Assisted Closure: The internal spring ensures rapid disc closure prior to flow reversal, mitigating water hammer and liquid surge pressures.
• High-Integrity Forged Body: Forged body components provide structural strength, thermal fatigue resistance, and durability under severe pressure shocks.
• Standardized Compliance: Built according to ISO 15761, BS 5352, and ASME B16.34 standards to guarantee dimensional interchangeability and international safety compliance.
• Erosion-Resistant Seating: Wear-resistant hard-faced seat and disc surfaces maintain seal integrity despite high-velocity fluid flow and abrasive particulate contact.
• Versatile Mounting: Unlike gravity-dependent swing check valves, the spring-loaded lift disc enables mounting in vertical pipelines with upward flow as well as horizontal orientation.

Applications

The KSB forged steel non-return valve is suitable for critical high-pressure, small-bore industrial piping networks, including:

• High-Pressure Steam Lines: Prevents steam condensate backflow in power generation plants, boilers, and auxiliary steam headers.
• Boiler Feedwater Systems: Protects high-pressure pumps against backpressure damage and severe reverse flow shocks.
• Petrochemical & Refining Facilities: Hydrocarbon transport, gas lines, and chemical processing lines where backflow poses process contamination or safety risks.
• High-Pressure Hydraulics & Utilities: Compressed gas distribution, boiler blowdown systems, and sampling lines.

Benefits

• Protection of Capital Equipment: Rapid check valve closure shields costly upstream machinery, feed pumps, and measuring instruments from reverse flow damage.
• Reduced Water Hammer: Fast spring-driven seating action minimizes hydraulic surge spikes and water hammer sound in liquid systems.
• Long Operational Service Life: Dense forged materials and hardened trim components minimize surface erosion and maintenance downtimes.
• Leak-Tight Isolation: Precision-guided disc combined with hard-faced seating delivers reliable tight shut-off during zero-flow conditions.
