1. Usage of the Product
for air conditioning system. Ingress of air into the piping system causes degrease of heat
, noise generation or corrosion of devices, etc. Air vent valves TA-2, 2C, 5, 5F equip
and can greatly reduce time required for water supply since they can exhaust
re quickly than conventional air vent valves.
2. Features
Equipped with a quick exhaust mechanism, air inside piping can be quickly
initial water supply, ensuring smooth water supply.
Wide pressure range than that of conventional air vent valves and applicable to from low pressure to high
Parts are easy to replace, maintain and inspect from outside even if the valve seat surface is
resistance since inside and outside of its body are coated by Nylon 11.
5 and TA-5F is made of bronze, these models are free from rusty water.
