DIN 11851 Connection Use

DIN 11851 outlet is selected where a detachable connection is required for product transfer lines, CIP returns, or networks with frequent disassembly for cleaning and inspection. Compared to ISO 228, DIN 11851 is more suitable for installations using standardized hygienic couplings.

Suitable Media and Applications

Compatible with liquids suitable for AISI 316L and PTFE: process water, foodstuffs, beverages, mild chemicals, CIP cleaning agents, and products with low fouling tendency. For food applications, M.O.C.A. CE 1935/2004 compliance can be requested.

Heated Jacket Variant

Model 153025E includes a heating jacket for applications where the product increases in viscosity, crystallizes, or solidifies near ambient temperature. Typical use cases: fats, syrups, resins, chocolate, or chemicals requiring thermal maintenance at the discharge zone.

Maintenance and Operational Limitations

Before maintenance, ensure system shutdown, zero pressure, and no flow through the valve. Operate open/close gradually to minimize hydraulic shock. Manufacturer recommends seal inspection every ~2,500 cycles, with increased frequency in corrosive or heavy-duty environments.

FAQ

Is this a control valve?
Not as a primary function. This is a full bore isolation valve.

Is it suitable for hazardous gases?
The manual states these valves are not safety valves and should not be used for hazardous gas service.
