Adhere to the correct electric regulating valve and pneumatic control valve device skill should always adhere to control Industrial Valves ( The regulator) Device manufacturers guidance and pay attention to point. Shanghai jian below Industrial Valves in the coaching on typical device for a brief summarized here. 1, read operating manual valve between the device and read guidance manual. Products described in this handbook and device before and device should be pay attention to safety issues and preventive measures. In accordance with the guidelines in the manual to do help to ensure that the device simple and successful. 2, admits regulator clean pipeline of foreign body may damage valve seal appearance or even prevent the movement of valve core, ball or butterfly plate to form a valve cannot be closed correctly. In order to reduce the possibility of risk situation happened before the valve to the plant cleaning all pipes. Admit cleared pipeline dirt, metal chips, welding slag, and other foreign matter. 3, to see the pipeline flange gasket in place to ensure that there is a lubrication is appearance. If the valve flow thread end, want to paint on the pipe pin the high-grade pipe sealant. Don't on female thread sealants, because on the female thread excess sealant will be packed into the body. Redundant sealant can form the card plug valve core or the accumulation of dirt, leading to the valve cannot be closed properly. 4, check valve, The regulator) Although the valve manufacturers will take some steps to avoid shipping damage, but this kind of damage or possible, and can be found in device before and informed. Don't plant now know valve has been damaged during transport and store. Transport device before, see and get rid of all stop, protective use plug or the lid of the gasket appearance, look at the body in order to make sure there is no foreign body. 5, use of pipe connection outstanding practice most of the control valve ( The regulator) To device at any position, but, the most commonly used method is to place the actuators are straight and located in the upper part of the body. If the level of actuator device is necessary, consider to add an actuator rated straight. Shall ensure that such a device body: the direction of flow and flow arrow or counselling manual indicated the direction of the joint. 6, ensure that the regulator with satisfy the space at the top and bottom of the valve in order to easily remove the actuator when viewing and protect or valve core. Space interval can usually found on from manufacturer decided that the shape of the Industrial Valves size. For the valve flange connection, ensure the flange surface accurately aligned so that the gasket surface evenly. Later, in the flange of gently tighten bolts, eventually in the form of a cross and tighten the bolt. Properly tighten to avoid uneven gasket load, and help to avoid leakage, also helps to avoid the damage of the flange or even split to sex. 7, when connecting flange and valve flange material is different, fluorine-butterfly butterfly valve this precaution is particularly important. Device on the control valve ( The regulator) Upstream and downstream of the pressure tube help to check the flow or pressure drop. Will bring pressure pipe received from bend, reducing or hole diameter of straight pipe. This kind of bearing can be lead to the inaccuracy of minus for fluid turbulent flow to a minimum. With a quarter or 3/8 of an inch ( 6 - 10毫米) The tube on the actuator pressure interface to connect to the controller. Insist on shorter interval, cohesion and try to reduce the number of pipe fittings and elbow in order to reduce the system time lag. If the interval it is necessary for a very long, so can in control valve ( The regulator) On the use of a locator or the supercharger.
