L&T Aquaseal-Plus Butterfly Valve (Integrally Moulded, Class 150): Technical Specifications, Features, and Buying Guide

Introduction

In high-performance industrial processing, chemical lines, water treatment networks, and HVAC systems, maintaining reliable flow regulation alongside robust pressure containment is essential. While PN 10 and PN 16 butterfly valves meet standard metric line requirements, process plants designed to ASME piping standards require pressure ratings aligned with ASME Class 150.

The L&T Aquaseal-Plus Class 150 Butterfly Valve is specifically engineered for demanding ASME Class 150 fluid handling operations. Manufactured by L&T Valves, this series features an integrally moulded elastomeric body liner that ensures bi-directional drop-tight shutoff, eliminates seat displacement, and maintains low operating torque across manual and automated valve configurations.

Product Overview

The L&T Aquaseal-Plus Class 150 is a wafer-style (or lugged option) concentric butterfly valve engineered with an integrally vulcanized elastomeric liner rated for ASME Class 150 pressure service.

Operator Configurations Available:

• Flow-Control Hand Lever: Designed for quick quarter-turn operation and multi-notch manual throttling on smaller line sizes.
• Worm Gear Unit: Features a self-locking gearbox and handwheel for effortless mechanical leverage on larger line sizes.
• Bare Shaft: Built with an ISO 5211 top flange for direct mounting of pneumatic actuators or electric motor drives.

The core feature of the Aquaseal-Plus series is its integrally vulcanized liner, which is heat-bonded directly into the metallic body casting. This design prevents seat distortion, movement, or collapse under dynamic flow velocities, full vacuum conditions, or high cycle frequencies.

Technical Specifications

The certified engineering parameters for the L&T Aquaseal-Plus Class 150 Butterfly Valve series are detailed in the table below:

Key Features

• Integrally Moulded Liner: Elastomeric seat is permanently vulcanized to the body casing, eliminating liner movement, stretching, or tearing under vacuum and dynamic flow.
• ASME Class 150 Rating: Built to match ASME flange bolt patterns and working pressure requirements across industrial process lines.
• Bi-Directional Sealing: Delivers zero-leakage, drop-tight shutoff in both flow directions up to full rated differential pressure.
• Gasket-Free Piping Interface: Vulcanized rubber extends over the body end faces, functioning as built-in flange gaskets to eliminate separate gasket costs.
• Blowout-Proof Stem Architecture: Retaining collar mechanism protects field personnel by preventing stem blowout under pressure surges.
• Standardized Automation Pad: Bare shaft models comply with ISO 5211 mounting dimensions for seamless actuator integration.

Applications

The ASME Class 150 pressure rating and vulcanized seat construction make the L&T Aquaseal-Plus Class 150 Butterfly Valve well-suited for heavy-duty utilities and process networks:

• Petrochemical & Industrial Processing: Utility water lines, non-corrosive chemical transfer, and solvent distribution skids.
• Water Treatment & RO Plants: High-pressure reverse osmosis (RO) feed lines, desalinated water transport, and sewage treatment headers.
• HVAC & District Energy: Commercial chilled water headers, condenser loops, and cooling tower isolation systems.
• Power & General Utilities: Auxiliary cooling water lines, low-pressure steam utility loops, and compressed air distribution.

Benefits

• Seamless ASME Pipeline Integration: Directly matches Class 150 pipe flanges and pressure-temperature ratings.
• Reduced Installation Expenses: Built-in flange face seals eliminate the need for separate rubber or spiral-wound gaskets during fitting.
• Low Dynamic Torque: Optimized disc contours and precision vulcanized seats keep operating torque low, allowing for smaller, economical actuators.
• Extended Life Cycle: Corrosion-resistant disc options paired with vulcanized rubber seats ensure long-lasting operational reliability.

Frequently Asked Questions (FAQs)

Q1: How does the L&T Aquaseal-Plus Class 150 differ from Aquaseal-16?

A: Aquaseal-16 is rated to metric pressure standards (PN 16 / 16 bar), whereas Aquaseal-Plus Class 150 is designed and pressure-rated to ASME Class 150 specifications, featuring flange bolt patterns and wall thicknesses tailored for ASME B16.5 / B16.34 piping systems.

Q2: What operator configurations are available for Aquaseal-Plus Class 150 valves?

A: It is available with a Flow-Control Hand Lever for manual operation on smaller sizes, a Worm Gear Unit for easy handwheel control on larger sizes, and a Bare Shaft (ISO 5211) for pneumatic or electric actuator mounting.

Q3: Are separate flange gaskets required when installing Aquaseal-Plus Class 150 valves?

A: No. The integrally moulded elastomeric liner extends over both body end faces, functioning as an integral flange gasket that seals directly against companion line flanges.

Q4: How can I procure authentic L&T Aquaseal-Plus Class 150 butterfly valves in Gujarat?

A: You can source authentic L&T Class 150 valves directly through an established L&T valve supplier in Gujarat like Awal Valve, complete with original factory test certification.
