SDD 911 |
• Plastic design, from ND 15 to ND 25
• Protection of pumps and process pipes
• Body: PPG, Glass fiber reinforced polypropylene
• Diaphragm: PTFE coated (EPDM core)
• Adjustable range: from 0.5 to 10 bar
- Water treatment plants (neutral and aggressive liquids)
The SDD 911 is used to maintain a constant pressure upstream in the event of pressure variation greater than the set pressure.
All wet parts are made of plastic components. The EPDM diaphragm, PTFE
coated, separates the mechanical parts from liquid circuit. Seat and O-ring seals
are in EPDM or FPM (according to application).
Wet parts are in plastics, no external metallic parts: allowing to install SDD 911 in aggressive, corrosive ambients.
SDD 911 can be used as a relief pressure valve or as a holding pressure valve. It
can be mounted in-line or as a bypass, according the application, in any position.
Caution: Not suitable as a valve with safety function requested in accordance with the EC Pressure Equipment Directive.
