Thermostatic valve thermostatic valve industry ahead of the five well-known advantages, thermostatic valve into electric thermostatic valve and Self-valve, due to the unique advantages of electric thermostatic valve to the working life has brought greater convenience. 1, the temperature control valve by the controller reads the current temperature and the observed electric thermostatic valve valve operating state, which is self-operated temperature control valve thermostatic valve and other products can not be achieved. 2, the temperature control valve of most models can be manually operated in case of power failure, which is the other electric thermostatic valve can not be completed. 3, thermostatic valve function with a scalable, Shanghai and Shanghai Valve Manufacturing Co., Ltd., such as remote setting, temperature compensation, over-temperature alarm, with heat metering and automatic meter reading, remote, these more humane, intelligent functions other thermostatic valve products can not match. 4, the temperature control valve has a proportional-integral (PI) or proportional integral derivative (PID) adjustment function, valves, control and stability, precision and other good quality products, but also other brands thermostatic valve products can not be surpassed. 5, the temperature control valve products for different site conditions, electric thermostatic valve control parameters can be flexibly adjusted to achieve system optimization results, perhaps many products are learning us, but we have never been surpassed. Pressure Test Method for various kinds of industrial valves including pneumatic valves as follows: 1. strength test valve pneumatic valve pressure test method shall be carried out at the ball half open. ① floating ball valve tightness test: The valve is partially open, one end of the introduction of the test medium and the other end closed; open the closed end of the examination several times when the ball is rotated, the valve is closed, at the same time check the packing and gasket sealing performance, You may not have leakage. Then introduced into the test medium from the other end, the test is repeated. ② fixed ball valve tightness test: Before the test the load rotate the ball several times, fixed ball valve is in the closed state, Guangzhou Kaiheng Valve Co., Ltd., the introduction of the test medium from one end to the specified value; with a pressure gauge to check the entrance seal performance, precision pressure gauges from 0.5 to 1, the range is 1.5 times the test pressure. Q within the prescribed time, there is no step-down phenomenon qualified; reintroduction test media from the other side and repeat the test. Then, the valve is partially open, closed at both ends, the cavity filled with media, check the packing and gasket at the test pressure, without leakage. Taiwan Toyama Valve Co., valves, valve out of Hong Kong, the Hong Kong valve provided by the Dongguan Science and Technology Co., Ltd. Valve Co., Ltd., Dongguan Ming Kong (www.gdmgfm.com) strong, credible, butterfly and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
