Metal Seat Eccentric Butterfly Valve,ASTM A216 WCB,14 Inch,150 LB,Flange End

Description

14 Inch 150 LB Metal Seated Eccentric Butterfly Valve for High-Temperature and Industrial Applications

The Metal Seat Eccentric Butterfly Valve (14 Inch, 150 LB, Flanged End) is designed for high-temperature, high-pressure, and abrasive media applications where a resilient seat cannot withstand operational conditions. Manufactured with ASTM A216 WCB carbon steel body and a robust metal seat, this valve delivers reliable shutoff, high durability, and exceptional performance in industrial piping systems.

The eccentric (offset) design ensures minimal seat wear, lower operating torque, and precise sealing. Flanged ends per standard dimensions allow for easy installation in pipelines, and the 150 LB pressure rating ensures suitability for moderate-pressure industrial systems.

This valve is ideal for steam, oil, gas, water, and chemical applications where metal-seated valves are preferred over resilient-seated types for high temperature or abrasive flow conditions.

Product Overview

Key Features

Robust Metal Seat

• Designed for high-temperature or abrasive service.
• Maintains bubble-tight sealing even under harsh conditions.
• Resistant to wear from solid particles, high flow velocities, and chemical attack.

Eccentric (Offset) Design

• Disc moves away from seat immediately after opening.
• Reduces friction and seat wear.
• Low operating torque allows smaller actuators or manual operation.

Carbon Steel ASTM A216 WCB Body

• Durable and suitable for industrial pressure and temperature requirements.
• Offers reliable mechanical strength for pipeline integration.
• Compatible with flanged connections per ASME/ANSI standards.

Flanged End Connections

• Standardized flange dimensions allow easy installation and replacement.
• Compatible with ASME B16.5 and API pipeline standards.

Flexible Operation Options

• Manual lever or handwheel
• Bevel gearbox for large diameter valves
• Electric, pneumatic, or hydraulic actuation

Applications

Steam Systems

• High-temperature steam pipelines
• Thermal power plants
• Process heating systems

Oil & Gas

• Refineries and petrochemical lines
• Gas distribution networks
• Hydrocarbon processing

Water & Wastewater

• Hot water or chemical-laden flow
• Industrial cooling or treatment systems

Chemical & Process Industry

• Aggressive chemical media
• High-temperature process fluids
• Abrasive suspensions

Technical Advantages

• Metal seat ensures durability in temperatures above 250°C and abrasive media.
• Offset design reduces wear, prolonging valve life.
• Flanged connections simplify installation and maintenance.
• Compact design allows for pipeline integration without excessive space.

Technical Specifications

Materials of Construction

Dimension and Pressure

Working Principle

1. Opening: The eccentric disc rotates away from the metal seat, minimizing friction.
2. Flow Passage: Media passes through full-bore or reduced-bore opening depending on valve design.
3. Closing: Disc moves toward the seat; final contact ensures a tight shutoff.

The eccentric movement extends the seat life, reduces torque, and ensures reliable sealing under high temperature and pressure.

Available Options

• Actuation: Handwheel, Gearbox, Electric, Pneumatic, Hydraulic
• Seat Material: Metal Alloy, Stainless Steel
• Disc Material: Stainless Steel, Alloy Steel, or Coated Steel
• Temperature Rating: Standard up to 425°C or custom high-temperature alloys
• Pressure Rating: 150 LB (standard), 300 LB optional

FAQ

What is the advantage of a metal seat butterfly valve?

Metal seat valves provide durability for high temperature, high pressure, or abrasive media where soft seats like EPDM or PTFE would fail.

What is an eccentric (offset) butterfly valve?

An eccentric or offset valve positions the disc slightly off-center from the seat and pipe axis, reducing friction and seat wear during operation.

Can this valve handle steam?

Yes. With the metal seat and carbon steel body, it is suitable for high-temperature steam applications.

What industries use metal seat eccentric butterfly valves?

• Power generation and steam systems
• Oil and gas processing
• Petrochemical plants
• Industrial water and wastewater treatment
• Chemical processing

Why choose ASTM A216 WCB?

ASTM A216 WCB provides excellent mechanical strength, pressure resistance, and is widely used for industrial carbon steel valves.

Quality Assurance

• Hydrostatic testing per ASME B16.34
• Seat leakage testing for zero leakage verification
