High Performance Butterfly Valve Manufacturer

WDL Valve supplies double-offset and triple-offset high performance butterfly valves for demanding isolation, automated cycling and severe process service. Wafer and flanged configurations, soft or metal seating, corrosion-resistant materials and pneumatic or electric actuation can be selected for the project conditions.

Double Offset vs. Triple Offset

Double-offset valves move the shaft away from the disc and seat centerlines to reduce rubbing during opening and closing. They are commonly considered where lower torque, frequent cycling and reliable shutoff are priorities.

Triple-offset valves add a conical sealing geometry that minimizes sliding contact and supports metal-seated shutoff in higher-temperature, higher-pressure or fire-safe service.

Configuration Options

Body pattern: wafer, lug or flanged according to piping layout and removal requirements.
Seating: resilient, reinforced polymer or metal seat according to temperature, media and leakage requirement.
Materials: carbon steel, stainless steel, duplex, nickel alloys, titanium or copper alloys where specified.
วิธีการทำงาน: lever or gearbox for manual service; pneumatic or electric actuation for remote and automated control.
Accessories: limit switches, solenoid valves, positioners and air-filter regulators as required.

การใช้งาน

High performance butterfly valves are evaluated for steam and condensate, oil and gas, petrochemical utilities, high-temperature gas, cooling water, vacuum, corrosive process media and frequent-cycle automated isolation. The correct offset, seat and material combination depends on the complete operating envelope, not only nominal line pressure.

คำถามที่มักถูกถาม

When should I use a triple-offset butterfly valve?

Triple-offset construction is commonly considered when metal seating, elevated temperature, higher pressure, fire-safe duty or reduced seat rubbing is important. The final choice depends on the required leakage performance and operating cycle.

Can a high performance butterfly valve be automated?

Yes. Pneumatic and electric actuators can be selected with positioners, limit switches and solenoid valves. Required torque, cycle time, fail position and control signal should be stated.

Which materials are available?

The range includes common carbon and stainless steels plus project-specific duplex, nickel alloy, titanium and copper alloy options. Wetted-part materials should be reviewed as a complete set.
