KSB Cast Steel Gate Valve (ASME B16.34)

Introduction

The KSB cast steel gate valve designed strictly to ASME B16.34 (specifically categorized under KSB's SICCA 900-2500 GTC series) is a heavy-duty fluid isolation valve engineered for severe high-pressure and high-temperature utility service. Constructed to withstand critical operating conditions in fossil-fuel power plants, boiler installations, and chemical processing facilities, this valve provides dependable bi-directional shut-off while maintaining low flow resistance across high-pressure pipelines.

Product Overview

The KSB SICCA 900-2500 GTC series comprises high-pressure cast steel gate valves engineered with a pressure-seal bonnet design. Operating via an Outside Screw and Yoke (OS&Y) assembly, a non-rotating rising stem, and a non-rising handwheel, the valve utilizes system internal pressure to tighten the bonnet seal gasket against the valve body. The sealing surfaces—including the flexible wedge face and body seat rings—are hard-faced with wear-resistant Stellite alloy to prevent wire drawing, erosion, and thermal galling during high-differential-pressure operation.

Technical Specifications

Key Features

• Pressure-Seal Bonnet Construction: Higher internal fluid pressure forces the bonnet wedge gasket tighter against the body ring, creating a zero-leakage bonnet seal under high pressures.
• Flexible Wedge Seating: Absorbs piping expansion forces and thermal shocks while ensuring tight bi-directional seating without thermal binding.
• Stellite Hard-Faced Seats: Full Stellite cladding across both wedge faces and body seat rings provides maximum defense against high-velocity steam erosion.
• Burnished Non-Rotating Stem: Extends gland packing life by eliminating rotational wear against the graphite packing rings.
• Integral Backseat Design: Provides positive stem back-sealing when the valve is fully open, protecting the gland packing chamber from continuous line pressure.

Applications

• Fossil-Fuel Power Stations: Main steam isolation, boiler feedwater line isolation, and reheater steam systems.
• Industrial Boiler Plants: High-pressure steam headers and boiler blowdown isolation lines.
• Refining & Hydrocarbon Processing: High-pressure catalytic cracking units and hydroprocessing loops.
• Petrochemical Complex: High-pressure gas and liquid transfer manifolds.

Benefits

• High Operational Reliability: Designed specifically per ASME B16.34 wall thickness and structural guidelines for high-stress steam applications.
• Reduced Maintenance Overhead: Stellite hard-facing and non-rotating stem movements extend maintenance intervals and reduce packing wear.
• Enhanced Safety at Elevated Pressures: Pressure-seal bonnet design eliminates traditional bonnet flange bolt elongation issues under extreme pressures.
