LIQUIfit Polypropylene Ball Valves
This range of valves offers an innovative solution in the treatment of water and the handling of beverages while protecting health. LIQUIfit’s
corrosion-resistant, all plastic design makes them ideal for water filtration units, coffee and beverage machines and a wide variety of other fluid
applications. The polypropylene material meets all FDA and NSF-51 requirements for food contact.
Features/Benefits:
•
Full-flow self-cleaning ball maintains the cleanliness of the circuit
•
Sealing technology using EPDM D seal
•
High temperature, scale-resistant Polysulfone ball
•
Tube retention with gripping ring prevents pumping effect
•
Push-in connection and disconnection
•
FDA compliant
Specifications:
•
Temperature range: +35°F to +200°F (1°C to 93°C)
•
O-ring seal material: EPDM
•
NSF-51 Listed
•
Pressure rated to 150 psi
Advantages:
•
Reduce costs – Built-in LIQUIfit connection eliminates the need for
a secondary fitting
•
Save space – Low profile design allows for easy assembly and
access where space is at a premium.
Assembly Instructions:
1.
Inspect the mating threads for debris or damage. Remove any
old fluoropolymer tape or sealant on previously used threads. If
threads are damaged, replace with new adapter before proceed-
ing.
2.
Apply 2 to 3 wraps of fluoropolymer tape, or an NSF/FDA ap-
proved silicone sealant. Do not use Plumbers Putty or Pipe Dope.
These chemically react with plastic materials and could cause a
failure.
3.
Align ball valve onto mating thread to ensure cross threading does
not occur.
4.
Screw ball valve onto mating thread 3 to 5 turns. This should be
sufficient to properly seal the threads.
5.
Pressurize system and check for leaks.
