Description:
Performance requirements:
1 opening and closing torque, under the nominal pressure, the valve opening and closing the
required maximum torque should not exceed 6Nm
2 air tightness, under the nominal pressure of 1.1 times, the valve is closed and any open state
should be no leakage.
3 vibration resistance, under the nominal pressure, the valve should be able to withstand the
amplitude of 2mm, frequency of 33 Hz 1/3 vibration, the valve on the threaded connection should
not loose, there is no leakage.
4 temperature resistance, under the nominal pressure, the use of the area of the valve
temperature is divided into: general area of -20~60 degrees Celsius. In the allowable
temperature range, should not leak.
