UKL Bellow Seal Valves

Introduction

In high-temperature thermal media and hazardous gas systems, conventional gland-packed valves often experience stem leakage due to packing degradation, leading to energy loss, environmental pollution, and plant downtime. UKL Bellow Seal Valves, engineered by Uni Klinger Limited, provide a zero-leakage isolation solution designed to eliminate fugitive emissions completely. By encapsulating the valve stem inside a multi-ply flexible metallic bellow, UKL bellow seal valves create a hermetic seal that prevents line fluid from escaping into the atmosphere.

Product Overview

UKL Bellow Seal Valves feature a metallic bellow unit welded to the stem at one end and to the bonnet/body assembly at the other, forming a leak-tight seal. Equipped with an auxiliary safety gland packing set above the bellow, these valves deliver double protection against stem leakage. Designed across globe and gate body configurations, UKL bellow seal valves meet international design standards including ANSI, API, BS, and DIN, making them suitable for critical steam, thermic fluid, chemical, and gas distribution lines.

Technical Specifications

Key Features

• Zero-Leakage Hermetic Seal: Flexible multi-ply stainless steel bellow isolates process fluid from the atmosphere, eliminating stem emissions.
• Secondary Safety Packing: Fitted with an adjustable gland packing set above the bellow assembly as a secondary barrier.
• Non-Rotating Stem Design: Prevents torsional twisting stress on the bellow assembly during valve opening and closing.
• Hardened / Stellited Seating Surfaces: Plug and seat mating areas are engineered for wear resistance and tight shut-off.
• Position Indicator & Lock: Built-in travel indicator shows open/close position, with optional locking features.

Applications

• Thermic Fluid & Hot Oil Loops: High-temperature Dowtherm, Santotherm, and thermal fluid heating loops.
• High-Pressure Steam Systems: Main steam lines, superheated steam loops, and boiler house headers.
• Hazardous & Toxic Gas Lines: Isolation of chlorine, ammonia, phosgene, hydrogen, oxygen, and vacuum services.
• Chemical & Petrochemical Processing: Transfer piping for corrosive chemicals, hydrocarbons, and heat transfer fluids.

Benefits

• Complete Energy Preservation: Prevents costly steam or thermal media leaks through the stem, maximizing boiler and system efficiency.
• Environmental & Workplace Safety: Eliminates toxic gas emissions and hot media leaks to safeguard plant personnel and maintain environmental compliance.
• Reduced Maintenance Overhead: Eliminates routine gland packing retightening and replacement, extending valve service intervals.
