Clamp Outlet Selection Criteria

Clamp connections are specified when the valve outlet interfaces with removable flexible or rigid process lines. Compared to ISO 228 threaded connections, clamp reduces disconnection time and facilitates visual inspection of contact surfaces. Compared to DIN 11851, clamp is preferred in sanitary networks where clamp fittings are favored over union nuts.

Media and Applications

Compatible with process water, foodstuffs, beverages, mild chemicals, and products suitable for AISI 316L and PTFE. Typical use cases: mixing tanks, storage vessels, CIP lines, liquid food units, cosmetics, and low-to-medium hazard chemical production.

Sealing and Maintenance

Primary seats and seals are PTFE. Stem and counterflange O-rings are FKM, with EPDM available on request. Selection depends on temperature, CIP chemistry, and product compatibility.

Heated Jacket Variant

Variant 153030E is used where thermal maintenance at the discharge area is required, e.g., for viscous, fatty, or solidifying products.
