Semi-lug WCB Body and CF8 Disc with Hydraulic Actuator Eccentric Butterfly valve

Product Overview:

The Semi-lug WCB Body and CF8 Disc with Hydraulic Actuator Eccentric Butterfly Valve is a high-performance valve designed for demanding applications that require fast operation, reliable sealing, and minimal maintenance. With a unique eccentric design and hydraulic actuator, this valve is ideal for handling high-differential pressures, while ensuring smooth operation and extended service life.

Design Features:

Valve Type: Double Offset Butterfly Valve with Soft Seat

The eccentric butterfly valve features a double offset design, where the valve stem axis is offset from both the sealing surface and the pipeline axis. This innovative design ensures that the disc quickly disengages from the seat during opening, significantly reducing friction and wear, and prolonging the service life of the valve seal.

Offset Design:

The offset design improves the valve's efficiency by allowing the disc to move with minimal resistance, providing smoother operation and reducing mechanical wear. The result is a valve that delivers high performance while requiring less maintenance.

Sealing System:

• Resilient Soft Seat:

The valve utilizes a resilient soft seat, commonly made of materials like EPDM, NBR, PTFE, etc. This soft seat design ensures excellent elastic sealing, achieving bidirectional zero leakage. It meets the stringent sealing standards such as ANSI Class VI, making it highly reliable for a wide range of industrial applications.

Material Specifications:

Body Material

The valve body is made of WCB Carbon Steel, providing strong structural integrity and excellent resistance to general pressures. This material ensures durability in high-demand environments, including industries with high flow rates or abrasive media.

Disc Material

The valve disc is crafted from CF8 Stainless Steel (304), known for its excellent corrosion resistance, high strength, and durability. The polished or coated surface of the disc ensures tight contact with the soft seat for a reliable seal while providing resistance against corrosion and wear.

Connection Design:

Semi-Lug Body:

This valve features a semi-lug body design, which allows for easy installation and disassembly. The semi-lug design includes tapped lug holes, making it possible to install the valve using through-bolts, similar to a wafer valve. The key advantage of this design is the ability to support the valve during pipeline disassembly, facilitating easier maintenance without removing the valve completely from the system.

Actuation:

Hydraulic Actuator:

The valve is equipped with a hydraulic actuator, offering high torque and fast response for applications requiring quick valve operation or handling high differential pressure to open. The hydraulic actuator is ideal for systems that require a higher degree of control and performance, such as in oil and gas pipelines, chemical processing, and other industrial applications.

Hydraulic Integration:

This actuator can be directly integrated into hydraulic control systems, providing seamless operation and greater control over valve movement. It’s designed to ensure high efficiency and minimal energy consumption while maximizing operational reliability.

Applications:

Water and Wastewater Treatment

Oil & Gas Industry

Chemical Processing

Power Plants

HVAC Systems

Pulp & Paper Industry

Pharmaceuticals and Food Processing

Key Advantages:

Minimal Wear and Tear: The eccentric design reduces friction, extending the lifespan of seals and reducing maintenance requirements.

Bidirectional Zero Leakage: The resilient soft seat design ensures leak-free operation in both directions.

Fast and Efficient Operation: With the hydraulic actuator, the valve delivers quick response times, ideal for high-pressure and fast-acting applications.

Easy Maintenance: Semi-lug design allows for easy valve removal and reinstallation during routine maintenance, saving time and labor costs.
