Sterivalve Heavy
Sterivalve Heavy – Ultra-Sanitary Butterfly Valve for High Pressures Sterivalve Heavy is an ultra-sanitary butterfly valve specifically engineered to ensure tight sealing, hygiene, and mechanical durability even under high-pressure conditions. Developed for the pharmaceutical, chemical, and food industries, this valve represents an evolution of the classic Sterivalve butterfly valve, featuring reinforced construction and high-performance materials.
Ideal for critical installations requiring structural robustness, contamination-free operation, and maximum process reliability, Sterivalve Heavy meets cGMP, ATEX, and food contact regulations (EC Reg. 1935/2004, FDA).
Its design allows rapid tool-free disassembly, minimizing intervention time and simplifying inspection by a single operator, even in highly complex environments.
Product properties
Application
- Bottom valve for pressure vessels, hoppers, mixers, tanks, and containers operating under high pressures.
- Flow interception points in bulk solids processes that operate in high-pressure environments or where maximum hygienic safety is required.
- Particularly suitable for plants requiring frequent sterilization (CIP/SIP).
Function
Sterivalve Heavy intercepts, isolates, or controls the flow of powders and granulates, even with significant pressure differentials between upstream and downstream.
Compared to a standard butterfly valve, the Heavy version provides:
- Enhanced structural robustness of the flange and valve body.
- Reinforced seals and mechanical solutions designed to ensure perfect sealing under demanding conditions.
- Ergonomic, tool-free assembly manageable by a single operator.
Solution
Sterivalve Heavy is the optimal solution where standard sanitary valves lack sufficient durability or reliability:
- Sealing problems under high pressure are resolved with reinforced design and materials.
- Extreme sanitation needs: the valve can be easily disassembled, inspected, and sanitized without compromising sterility.
- Reduced maintenance time: quick disassembly system allows rapid inspection and replacement even in confined spaces.
Advantages and Customer Benefits
- Engineered to withstand high pressures without deformation, sealing failure, or cross-contamination.
- Meets cGMP, ATEX, and EN 1935/2004 standards, providing safety in hazardous environments and food compatibility.
- Surface finishes Ra<0.5 µm on contact surfaces, absence of dead zones, electropolishing options, and FDA/USP VI certified materials.
- Ergonomic and modular design enables intuitive installation by a single operator.
- Reduced downtime, fewer maintenance interventions, increased durability, and reliability translate to higher production efficiency.
- Each valve is individually numbered, tested, and manufactured in Italy under an ISO 9001:2015 certified quality system.
