System Valves and Accessories
The Importance of Valves and Accessories for Plastics Conveying Systems
No selection of Plastics Auxiliary Equipment for Plastics Conveying Systems is complete without a wide array of valves and accessories to complement the Plastics Auxiliary Machinery.The list might include things like Machine Hoppers or Machine Bins which mount on machine throats. Other things that are likely included are Vacuum Purge valves, Proportioning Valves, External Line Valves, Discharge Selection Valves, Ā Vacuum Takeoff Boxes, Closed Loop Relief Valves, Station T Sequencing Valves and External Line Valves.
These Plastics Conveying System Accessories all serve valuable purposes within systems used for conveying plastics pneumatically.
-
Air Flow Regulators and Flow Reducers
AFR for line sizes up to 2.5″ and FR Series up to 4″ diameter line size
Reducing airflow inside pellet conveying lines is an important way to minimize damage to both the conveying lines and the pellets being transported. These products are an economical way to accomplish that instead of constantly replacing worn-out sections of conveying lines.
-
EFV External Fill Valve
EFV Series External Fill Valves for 1.5″ through 3″ line sizes
The EFV-R Series is a stand-alone valve that can be utilized with vacuum receivers that require remote-mounted fill valves, like the Station T Valve. The EFV is not replacing the Station T valves. It is an alternative that may help in cases where the Station Tās are not performing as desired.
-
EPV External Proportioning Valve
Inlet/Outlet O.D. 1.5ā – 4ā (3.9 – 100 mm)
External proportioning valves are used as a material line selector at the receiver inlet, typically in regrind proportioning applications. The EPV can also be used for purging material lines to prevent build-up and plugging of the material lines.
-
Machine Hopper Assemblies
8 to 38 lb. (3.6 to-18.8 kg) Capacity
These multi-purpose hoppers can be mounted on feeder machine adapters or directly on machine throats.
-
Vacuum Purge Take-Off
VPT Series 1.5″ – 2.5″ (38-65 mm)
Combination take-off box/purge valve is mounted below a drying hopper or other material storage vessel and allows conveying followed by line clearing with ambient or dry air.
-
ELV External Line Valve
Inlet/Outlet O.D. 1.5″ – 4″ (3.9 – 100mm)
Provides in-line control of vacuum material flow. ELV is used as a positive vacuum seal at the receiver inlet when not moving material, typically in common material line conveying systems
-
DSV Series Discharge Selection Valve
For Closed Loop Conveying (Includes Coupler)
The DSV provides return air conveying from the pump outlet, with pressure relief, back into a closed loop dry air conveying system.
-
CLR Closed Loop Relief Vent
Used in Closed Loop Conveying
The CLR provides pressure relief in a closed loop conveying system.
-
SV Station T Sequencing Valve
Inlet/Outlet O.D. 1.5″ – 4ā (38-100mm)
One Station T valve is used with a VR Series receiver in a Central Conveying System to provide vacuum sequencing with other system stations.
-
VPV Vacuum Purge Valve
Outlet O.D 1.5″- 2.5″ (25 – 65mm)
Combination take-off box/purge valve allows conveying and line clearing with ambient or dry air.
-
VTB Series Vacuum Take-Off Box
Provides a connection for vacuum conveying from a drying hopper, surge bin or other material vessel.
The VTB Series Vacuum Take-Off Boxes (except VTB-14) are equipped with one or more cartridge filters providing air inside the box for conveying. Standard probes allow hard-plumbing directly to stationary conveying lines, eliminating the need for flex hose.
