Key Benefits of SD4 series

Excellent hygienic characteristics due crevice-free sealing. Safe incompatible media separation.
Quick and easy service of the valve. Flanged valve body closure for safe and controlled disassembly and assembly of valve insert.
Ball-shaped housing without sump or dome.
Sealings with metallic stop ensure limited elastomer compression and, consequently, avoidance of sealing overstress. Clear identification markings ensure prompt and fail-safe identification of seals during maintenance.
Controlled by a single solenoid valve, so no additional control is required.
