Built-in backflow prevention function, negative pressure operation function, pressure balance function, automatic return water drain stopper and strainer; used mainly in hot water heat exchangers.
[Features]
· The pressure-balancing valve mechanism ensures that the pressure on the secondary side is kept constant without being affected by pressure on primary side.
· Maintenance and inspection are easy as the strainer, check valve, and strainer cap can be removed without using tools.
· The piping installation direction (vertical horizontal) is unrestricted.
· Since the drainage plug is a push operated type, it automatically returns to its original position without having to be returned manually.
· The GD-91R type pressure reduction valve uses parallel threads for connection, and thus piping can be performed easily using cap nuts.
· Valve body and the diaphragm have excellent resistance to chlorinated water.
