High value, Low life cycle costs:

• “All-In” standard features such as seat lift actuator and cross-port housing provide exceptional value
• Reduced inventory costs with same seal kit used on multiple size ranges: DN40-DN65 (1.5”-3.0”) and DN80-DN100 (4.0”)
• Low air consumption and air supply requirements
• Leak drain with clamp connection for CIP fluid collection
• Long housing ports ease manifold building
• Integrated shaft seal flush reduces need for external piping

Reliable performance:

• Design based on the proven D4SL model
• Tank side holding pressure greater than 5 bar (73 PSI)
• Long stroke for gentle product handling (ex: particulates) and low flow resistance
• Balanced design helps to prevent hydraulic blocking and enables flexible flow direction without slamming
• Heavy-duty bolted flange connection between tank/housing/insert provides secure, controlled assembly/disassembly of valve insert
• No compressed air needed for removal and servicing
• Range of control units and bus communication for automated operation

Cleanability:

• Designed to the latest global hygienic standards
• Cavity spray cleaning as standard
• Radial seal design provides minimal switching leakage
• Extensive cleaning of product contact seals
