Stainless Steel Monoblock Ball Valve

The stainless steel monoblock ball valve is specially designed to control the flow of liquids and gases. Its body is constructed as a single piece to ensure high leak-tightness. The perforated ball inside the valve rotates to start or stop the flow.

This operation can be performed using a manual lever or an automatic actuator. The monoblock design eliminates weld points, minimizing the risk of leaks. Additionally, the use of steel provides high resistance to corrosion.

This design also helps minimize wear over time. It is engineered for long-lasting use, with maintenance requirements kept to a minimum.

Where to use?

Monoblock ball valves are used in a wide range of industrial and commercial applications. They are especially preferred in pipelines carrying chemical substances.

They are commonly used in water treatment, steam lines, and pressurized gas systems. In the food and beverage industry, they are safely preferred due to their hygienic design.

They are also used in pharmaceutical, petrochemical, marine engine, and power plant applications. The monoblock design allows for easy integration into more compact systems.

It is designed to operate safely under high temperatures and pressures for extended periods. For this reason, it is preferred in sensitive applications to ensure system safety.

How is the Working Principle?

This type of valve features a spherical ball that is rotated using a stem. The ball, which has a hole through its center, is aligned either parallel or perpendicular to the pipeline.

This allows the flow to be either released or completely stopped. The rotation of the ball can be performed manually or with an automatic motor.

Additionally, the design ensures high sealing between the ball and the seat. This construction allows safe operation even during sudden pressure changes.

What Are the Technical Specifications?

Monoblock ball valves are manufactured in various sizes and connection types. The following technical details represent their general features:

• Body Material: AISI 304 or AISI 316 Steel

• Ball: Chrome-plated steel

• Conta: PTFE (Teflon)

• Connection Type: Threaded BSP – NPT, Flanged

• Pressure Rating: PN16 / PN40

• Temperature Range: -20°C to +200°C

The products can be manufactured in compliance with ISO 5211 mounting standards. All these details can be customized according to system requirements.

Why Should It Be Preferred?

This valve type requires less maintenance thanks to its single-piece body design. The absence of welds provides a significant advantage in terms of leak-tightness.

The steel body provides high resistance to corrosion and wear. Additionally, its quick open-close feature helps prevent time loss.

It ensures hygienic and safe operation in food, pharmaceutical, and chemical processes. With its long service life and low operating costs, it helps improve overall system efficiency.
