JRV-ST11直動式減壓閥 韓國朝光減壓閥
|
■ FEATURES
|
1. This valve can operate stably from extremely large flow by the employment of special synthetic rubber diaphragm.
2. Maximum reducing pressure is very big.
3. Minimum differential pressure is very small.
4. This valve can be used while the secondary pressure is a minimum pressure.
5. Simple valve structure and small moving part means less mal-functioning of the valve by foreign matters as well as an easy maintenance.
6. Screwed type connection allows an easy installation. |
