Built to withstand challenging conditions, the Sferaco 171 features a compact design that minimises installation space while maintaining excellent sealing integrity. The knife-shaped gate cuts cleanly through viscous media, making it ideal for applications where conventional gate valves may struggle. Engineered for durability and ease of maintenance, this valve is a trusted choice for municipal utilities, industrial plants, and infrastructure projects across Europe. Its proven design ensures long service life and cost-effective operation.

Equipped with double acting pneumatic actuation, this valve enables rapid, automated operation in both opening and closing directions. The pneumatic system provides smooth, controlled movement ideal for remote or process-integrated applications where manual operation is impractical. The double acting design offers superior control and responsiveness, making it suitable for high-cycle applications and systems requiring frequent valve positioning. Integration with standard pneumatic control systems simplifies installation and reduces overall project complexity.

Built for Demanding Industrial Applications

The Sferaco 171 Knife Gate Valve is designed for industrial systems that require dependable shutoff and smooth operation. With a 6" DN150 size and PN10 pressure rating, it is well suited for handling challenging media in pipelines where isolation must be fast and reliable. Its knife gate design helps cut through heavy or abrasive materials, making it a strong choice for processes that involve slurries, wastewater, pulp, or other difficult fluids. Built with durability in mind, this valve supports efficient flow control while helping reduce downtime and maintenance needs in demanding environments.

Double Acting Pneumatic Performance

This model uses a double acting pneumatic actuator, giving the valve consistent opening and closing control through compressed air. The double acting design provides positive movement in both directions, which helps improve response time and operational accuracy. It is especially useful in automated systems where reliable valve positioning is important for safety and process efficiency. Because the actuator does not depend on spring return, it is often preferred in applications that require stable force and repeated cycling. This makes the valve a practical solution for modern industrial installations that need dependable remote operation.

Practical Design for Efficient System Integration

The Sferaco 171 Knife Gate Valve is built to integrate easily into standard industrial piping systems. Its PN10 rating supports use in moderate-pressure applications, while the DN150 connection size makes it a versatile option for medium to large flow lines. The compact and functional design helps reduce space requirements without sacrificing performance. This makes installation and system layout more manageable for engineers and maintenance teams. When used in the right process conditions, the valve offers a dependable balance of strength, control, and ease of use, making it a valuable component in many industrial flow systems.

Reliable Choice for Process Control Needs

For facilities looking for a durable and efficient shutoff solution, this Knife Gate Valve offers a smart combination of performance and automation. It is especially useful where frequent cycling, tight isolation, and resistance to tough media are important. The valve’s pneumatic actuation supports automated process control, helping operators manage flow with less manual effort. Its sturdy construction and industrial-grade design make it a trusted option for demanding environments. Whether used in water treatment, slurry handling, or general industrial processing, the Sferaco 171 delivers practical performance and reliable sealing for everyday operation.
