ยินดีต้อนรับสู่บริษัท Xiamen WDL VALVE Co., Ltd.
Industrial Butterfly Valve Manufacturer
WDL Valve manufactures industrial butterfly valves for isolation and flow control across water, oil and gas, petrochemical, power, marine and corrosive process services.
Our portfolio includes concentric soft-seated, high-performance double-offset and metal-seated triple-offset designs, with wafer, lug and flanged body styles plus manual or automated operation.
Butterfly Valve Designs by Service Duty
Butterfly valves combine compact face-to-face dimensions with fast quarter-turn operation. The correct design depends on temperature, pressure, leakage target, cycling frequency, fluid abrasiveness and compatibility with the seat and disc materials.
Concentric
Soft-seated valves for water, air and compatible low-to-moderate temperature services with bubble-tight shutoff.
Double Offset
High-performance geometry reduces seat wear and supports higher pressure, temperature and cycle requirements.
Triple Offset
Metal-seated construction minimizes rubbing and is selected for demanding hydrocarbon, steam and high-temperature duties.

Materials and Automation Options
Body and disc materials can include carbon steel, stainless steel, duplex, titanium, nickel alloys, Monel, Hastelloy, Inconel, zirconium, NAB C95800 and super-austenitic grades. Seat selection may include elastomer, PTFE-based or metal-laminated configurations.
Lever, gearbox, pneumatic and electric operators are sized against calculated torque, differential pressure, cycle time, fail position and control requirements.
Applications, Standards and Inspection
Industrial butterfly valves serve cooling water, seawater, HVAC, fire water, tank farms, pipelines, refineries, chemical plants, power stations and marine systems. Design and testing can be aligned with API, ASME, EN, ISO or the approved project specification.
WDL Valve can provide dimensional records, material certificates, pressure-test reports, coating documentation and third-party inspection support. Fire-safe, fugitive-emission, anti-static and low-temperature requirements are reviewed at quotation stage.
ข้อมูลที่จำเป็นสำหรับการคัดเลือก
Provide valve size, pressure class, body style, flange standard, body/disc/seat materials, medium, design temperature and pressure, shutoff requirement, operating frequency, actuation details, quantity and inspection requirements. For control duty, include flow rate and differential pressure data.
Industrial Butterfly Valve FAQs
What is the difference between double-offset and triple-offset butterfly valves?
Double-offset valves reduce seat friction and often use resilient or polymer seats. Triple-offset valves add a conical sealing geometry and commonly use metal seats for higher-temperature or severe service.
When is a soft-seated butterfly valve appropriate?
Soft seats are suitable when fluid compatibility and temperature permit and tight shutoff is required. Seat material must be checked against the process medium and cleaning chemicals.
Can WDL Valve supply complete actuated packages?
Yes. Pneumatic or electric actuator packages can include solenoids, limit switches, positioners and manual overrides according to the control philosophy and hazardous-area classification.
