Signal soft seal gate valves are often used in automatic sprinkler fire protection piping systems to monitor the water supply piping and to indicate valve opening remotely. Red-type gate valves and open indicator gate valves are also often used in fire fighting
systems. If the gate valve is installed at a higher position from the ground, the rising-type gate valve is generally used to indicate the valve opening obviously. If the installation position is lower, the opening indicator gate valve is required.
Characteristics of signal soft seal gate valve:
1. Signal gate valve fluid resistance is small
2. Open and close with less effort.
3. The flow direction of the medium is not restricted, not disturbing, not reducing the pressure.
4. Simple shape, short structure length, good manufacturing technology, wide range of application.
