KSB Cast Steel Gate Valve API 600 & ASME B16.34 | Awal Valve

KSB Cast Steel Gate Valve (API 600 / ASME B16.34)

Introduction

The KSB cast steel gate valve to API 600 and ASME B16.34 (specifically categorized under KSB's SICCA 150-600 GTC series) is an industrial valve engineered for bi-directional flow shut-off in high-demand fluid handling systems. Designed to meet stringent international manufacturing standards, this heavy-duty valve delivers tight sealing, robust structural integrity, and long service life across power plants, oil refineries, and chemical process facilities.

Product Overview

The KSB SICCA 150-600 GTC series comprises heavy-duty cast steel gate valves manufactured with a bolted bonnet design and an Outside Screw and Yoke (OS&Y) construction. Operating with a non-rotating rising stem and a non-rising handwheel, the valve uses a flexible wedge design that adjusts to valve seat alignment under varying thermal and mechanical stresses. The seating surfaces are hard-faced with Stellite or 13% Cr steel to prevent wire drawing and seat erosion during high-pressure fluid operation. The valve body provides a full bore per API 600, minimizing flow resistance and pressure drop across the line.

Technical Specifications

Key Features

• Flexible Wedge Design: Ensures exact adaptation to body seat rings, maintaining tight shut-off even during temperature fluctuations and pipeline deformation.
• Full Bore Flow Path: Manufactured in accordance with API 600 full bore dimensions, delivering streamlined flow with negligible pressure drop.
• Stellite Hard-Faced Seats: Stellited body seat rings seal-welded to the body provide high resistance to wear, erosion, and thermal galling.
• OS&Y Construction with Burnished Stem: Stem thread remains external to the process fluid, while burnished stem surfaces extend gland packing lifespan.
• Self-Aligning Gland Packing: Two-piece gland follower design distributes packing gland pressure evenly, minimizing stem binding and leak paths.
• Encapsulated Bonnet Gasket: Controlled-compression graphite gasket prevents blowing out under pressure spikes.

Applications

• Fossil-Fuel & Thermal Power Stations: Main steam lines, boiler feed lines, and auxiliary steam isolation.
• Refineries & Petrochemicals: Process unit isolation, tank farm manifolds, and hydrocarbon transport.
• Chemical & Process Industries: Isolation of non-aggressive or aggressive process fluids, depending on body material grade.
• Pulp & Paper Plants: High-pressure steam distribution and liquor process pipelines.
• General Industrial Utilities: Water, gas, and oil fluid distribution systems requiring dependable shut-off.

Benefits

• Dependable Isolation: Flexible wedge seating and differential seat-to-wedge hardness ensure tight shut-off under low and high pressure conditions.
• Reduced Maintenance Costs: Stellited seats and burnished stem finishes limit seat wear, gland erosion, and frequent repacking needs.
• High Temperature Stability: Robust cast alloy steel bodies (such as WC6) tolerate working environments up to 593°C without mechanical degradation.
• Compliance Assurance: Designed to rigorous API 600 and ASME B16.34 standards, facilitating seamless integration into standardized industrial piping systems.
