Dec Safe Dock Valve: Flexible connection with full containment
Available from Dec USA Inc
Dec Group has unveiled the latest addition to its ‘Containment out of the Box’ powder handling solutions, the Dec Safe Dock Valve.
Safe Dock Valve allows connection of a Powder Transfer System (PTS) flexible hose to rotating equipment in a fully contained way, using a unique split valve system.
Applications and Features
The Safe Dock split valve can be used in various applications:
• Contained discharge from a dryer via continuous liner using the PTS-DosiValve system
• Container sampling with an MPTS system
• Filling of suspension in a dryer
In all cases it maintains full equipment function and flexibility, combined with very high degree of powder containment.
Design and Engineering
The valve is full bore with various internal diameters, from DN 25 to DN 80, matching PTS hose bores, to prevent any product blockages or obstruction to flow. The split valve features a flexible ‘active’ section, hosting all valves and controls, that mates with a ‘passive ‘section that is rigidly attached to the equipment. This provides a solution that is easier to manipulate and operate, as well as a CIP capability that can be used before disconnection to ensure total containment.
Cleaning and Drying
In cleaning tests, a Safe Dock Valve that had been used for one hour of powder circulation (using Lactose) was subjected to three minutes of cleaning with water injection. The result was no powder left inside the split valve.
