Application:
Often used on both the blower and trailer, designed to prevent product backflow if a product line
should become plugged.
Standards:
Bayco High Flow series swing check valves have 2", 3" or 4" connection choices: female NPT,
round TTMA flange or square TTMA flange.
Materials:
Aluminum body and inspection lid, stainless steel hardware, metal-to-metal, EPDM (250°F / 121°C)
or silicone seals (400°F / 204°C) are available (seal availability is dependent upon the model, see
chart below for more information)
Features & Benefits:
•
Choice of seals, metal-to metal, Buna or silicone
•
Choice of connections female NPT, round TTMA flange or square TTMA flange
•
Flapper return springs are standard
•
Huck bolted flapper assembly prevents loose parts from contaminating the product.
•
Inspection lids can be removed to facilitate routine flapper assembly inspections (system must
not be in service during inspections or repair).
•
Complete repairs can easily be carried out on all high flow swing check valves without removing
from the tank.
•
When in use the flapper can swing completely out of the air path, resulting in increased air flow
and subsequently increased product flow.
