    Testing of Needle Valve

    Each set of HI-TEK threaded Needle Valve has been tested in the factory with nitrogen at 1000Psig (69bar), and the maximum allowable leakage rate of the valve is 0.1 standard cm³/m in. The shell test is based on the use of leak detection fluid, and there is no detectable leak.


    Note: Packing may need to be adjusted during the service life of the valve. Valves that have not been opened for a period of time will have a higher initial force torque.
