Sanitary Manual Lift Relief Valve
Sanitary Manual Lift Valve, also known as a pull-handle regulating valve, is a hygienic pressure control and operation device designed for food, beverage, pharmaceutical and fine chemical process tanks and vessels. It features a long lever-operated mechanism that allows operators to manually lift or lower the valve stem to adjust the opening, enabling flexible control of pressure relief, gas venting, flow regulation or system shut-off according to real-time production needs. Made of high-grade stainless steel with sanitary quick-clamp connections, it meets strict hygiene standards, supports easy disassembly and cleaning, and is widely used in processes requiring on-site manual intervention.
Sanitary Manual Lift Relief Valve
Key Features
- Constructed from premium 304 or 316L stainless steel with a mirror-polished finish, ensuring excellent corrosion resistance and compliance with food-grade hygiene requirements.
- Long lever-operated design allows convenient, precise manual control of valve opening for pressure adjustment, venting, or shut-off without removing the valve from the system.
- Sanitary quick-clamp connections for fast, tool-free installation, disassembly and cleaning, simplifying routine maintenance in hygienic production environments.
- Robust and compact structure with smooth internal surfaces to prevent media buildup and ensure hygienic operation.
- Multi-functional design supports various operations including pressure relief, gas venting, flow control and temporary system isolation.
- Reliable sealing performance with food-grade gaskets, effectively preventing leakage during operation to maintain process stability.
