Swing Check Valves
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.
