Dec Safe Dock Valve

Flexible connection with full containment

Overview :

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-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.

The split valve system is also easy to dry. Water CIP cleaning, as described above, was followed by

five minutes of drying with air injection resulting in all surfaces 99% water-free.

Features and Benefits :

The Dec Safe Dock-Valve delivers a series of clear user benefits:

· Free and unobstructed powder flows

· Assured high containment

· Low OEL levels

· Easy connection and disconnection

· Direct access to valve controls

· Easy and thorough CIP/SIP, drying
