Purpose: YX741X adjustable relief valve installed in water supply and drainage, construction, petroleum, chemical, gas (gas), food, medicine, power stations, nuclear power, in areas such as management will be higher upstream pressure to conform to the requirements of the low pressure normal use. Characteristics: 1. To reduce the effect is reliable, outlet pressure is not affected by the influence of inlet pressure and flow rate and can reduce dynamic pressure, can reduce static pressure again. 2. The adjustment is easy to operate, need to adjust the guide valve adjusting screw, can obtain accurate and stable pressure.

3. The energy saving effect is good, with half a straight port, wide body and wait until the flow cross-sectional area design, resistance losses small.
4. The key parts adopt special material, basic need not maintain
Materials of major parts:
