High-Performance Electric Socket Weld Ball Valve: Engineered for Durability and Easy Maintenance

For critical industrial applications demanding high-integrity, permanent connections, the electric actuated 3-piece socket weld ball valve provides an unmatched combination of strength, performance, and maintainability. This valve is engineered for high-pressure and high-temperature services where threaded connections are not suitable. The socket weld ends ensure a robust, leak-proof seal once welded into a pipeline, while the intelligent 3-piece body construction offers the unique advantage of easy inline maintenance. Paired with a powerful and reliable electric actuator, this socket weld ball valve delivers precise automated control for a wide range of media, including water, oil, gas, steam, and corrosive chemicals. It is the definitive choice for industries like petroleum, chemical, power generation, and metallurgy where performance and reliability are paramount.

Core Advantages & Features

Secure, Leak-Proof Socket Weld Connection

The defining feature of this ball valve is its socket weld end connections. This design involves inserting the pipe into a recessed socket on the valve before applying a fillet weld around the joint. This method creates an exceptionally strong and durable connection that is far more reliable than threaded ends in high-pressure systems. The result is a permanent, maintenance-free seal that eliminates potential leak paths, which is critical for handling hazardous or valuable media. The smooth internal bore transition also contributes to a high flow coefficient and low flow resistance.

Maintainable 3-Piece "Swing-Out" Body Design

While the ends are welded permanently, the valve body is ingeniously designed for serviceability. The 3-piece construction consists of two end caps and a central body that houses all the valve’s core components (ball, seats, and seals). By removing the body bolts, the center section can be easily swung out or removed from the line for quick and convenient maintenance, such as seat or seal replacement. This feature provides the permanence of a welded valve with the serviceability of a flanged valve, significantly extending the product’s service life and reducing long-term operational costs.

High-Performance Materials for Demanding Service

This socket weld ball valve is constructed from materials designed to withstand rigorous industrial conditions. The body and core components are made from high-grade stainless steel (SS304, SS316, SS316L), offering excellent strength and corrosion resistance against a wide variety of media. To accommodate different service temperatures, the valve is available with two premium seat material options:

PTFE: Suitable for a wide range of chemical applications with temperatures from -20°C to 180°C.
PPL: Designed for higher temperature services, including steam, with a range from -20°C to 250°C.

Reliable Electric Actuation for Automated Control

The valve assembly is equipped with a robust electric actuator for dependable automation. The actuator features a hard aluminum alloy body with an IP65 protection rating, making it suitable for most industrial environments. A high-efficiency, self-locking gear train ensures the valve stays in its set position without drifting. The actuator is available in two primary control modes: a standard ON/OFF type for isolation and an adjustable (modulating) type for precise flow control. An explosion-proof option is also available for use in hazardous locations.

Broad Industrial Applications

The robust design and high-pressure capabilities of this electric socket weld ball valve make it a vital component in numerous heavy-duty industries, including:

Petroleum and Petrochemical
Химическая обработка
Metallurgy and Steel Mills
Power Generation Plants
Water Conservancy and Urban Construction
General Machinery and Coal Industries

What is a socket weld ball valve primarily used for?

A socket weld ball valve is used for high-pressure and high-temperature applications where a permanent, leak-proof connection is critical. It is commonly installed in steam, oil, gas, and chemical lines in industries like petroleum, power generation, and chemical processing.

What is the main benefit of a 3-piece ball valve design?

The primary benefit of a 3-piece design is easy maintenance. The center section of the valve, which contains the ball and seats, can be removed for service by unfastening the body bolts, without having to cut the welded valve out of the pipeline.

What are the pressure and temperature ratings for this valve?

This ball valve can handle high pressures, with ratings available up to 6.4 MPa (64 bar) or higher. Its temperature rating depends on the seat material: up to 180°C with PTFE seats and up to 250°C with PPL seats.

Can this socket weld ball valve handle steam?

Yes. When equipped with PPL (Polyparaphenylene) seats, the valve is rated for temperatures up to 250°C, making it well-suited for many industrial steam applications.

Is an explosion-proof version of the actuator available?

Yes, the documentation confirms that an explosion-proof electric actuator can be equipped with this ball valve, making the assembly suitable for installation in hazardous environments where flammable gases or dust may be present.
