Our Single Seat Valve, also known as the Shut-Off and Divert Valve, is designed for optimal hygienic flow management. Manufactured in high-quality Stainless Steel 304L or 316L, and based on the trusted Cipriani Harrison design, this versatile valve facilitates seamless shut-off or diversion between different process pipelines. Thanks to its one-piece body construction and maintenance-free actuator, the valve offers reduced product entrapment, minimal wastage, and simple maintenance, a reliable solution for critical processing needs.

Options
- One-Piece Body Construction: Forged from solid bar for superior hygiene, minimising joints and potential contamination points
- Compact and Lightweight: Thanks to the integrated design, it offers easy handling and installation without compromising strength
- Minimal Product Trap: Special internal design reduces product hold-up, dead legs, and maximises process yield
- Increased Stroke Travel: Enables the smooth passage of viscous liquids and fluids with suspended solids
- Modular Design: Easily upgrade from manual to automated operation, or switch to a high-pressure actuator without replacing the whole valve
Maintenance is simplified with clamp connections between the valve body, yoke, and actuator, ensuring quick assembly and disassembly.
The Single Seat Valve is equipped with:
- PTFE and FDA EPDM seals as standard
- Comprehensive seal options are available to suit various chemical, temperature, and pressure requirements.
- Special aseptic configurations feature a one-piece diaphragm for hermetic sealing against atmospheric contamination.
This advanced seal technology ensures extended service life even in challenging process environments.
