The installation of pneumatic pneumatic control valve

About pneumatic pneumatic - valve installation instructions as follows: 1. Adhere to the correct installation technology should always comply with pneumatic pneumatic - valve manufacturers installation instructions and attention points. Here the typical installation instructions as a simple conclusion. 2. Read the operation manual before installing the pneumatic pneumatic control valve, read the instruction manual. Products described in this instruction manual before installation and the installation should pay attention to safety issues and preventive measures. According to the guidelines in the manual to do help to ensure the installation simple and successful. 3. Verify that the foreign body in pipeline cleaning it might damage the pneumatic pneumatic - valve sealing surface or even hinder the valve core and valve ball or disc movement caused by the valve cannot be closed properly. In order to reduce the possibility of danger happens, need to clean all before install pneumatic pneumatic regulator valve pipe. Confirm having cleanup dirt, metal chips, welding slag, and other foreign matter. In addition, check the pipeline flange in order to ensure a smooth surface of the gasket. If there is a threaded end pneumatic control valve of pneumatic valves, 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 will result in the accumulation of valve core card plug or dirt, leading to can't normally closed valve. 4. Check the control valve ( Pneumatic control valve) Although valve manufacturers will take some steps to prevent the transport damage, but this kind of damage or possible, and can be found and notified prior to installation. Do not install already know that has been damaged during transportation and storage of the valve. Before installation, check and remove all transportation stop, protective use plug or the lid on the surface of the gasket, internal check valve body to ensure that there is no foreign body. 5. Use of pipe connection good practice most of pneumatic pneumatic - valve can be installed in any position, however, the most commonly used method is to enforcement agencies vertically and are located in the upper part of the body. If actuators level installation is needed, of the actuator is considered adding an extra vertical support. Shall ensure that such installation body: the direction of flow and flow arrow or the direction indicated by the instruction manual. 6. Ensure that with sufficient space at the top and bottom of the valve so that at the time of inspection and maintenance easily remove the actuator or valve core. Space distance can usually figure from pneumatic pneumatic - valve manufacturer of dimension. For the valve flange connection, make sure the flange surface accurately aligned evenly so that the gasket surface contact. Later, in the flange of gently tighten bolts, the last in a staggered form and tighten the bolt. Properly tighten to avoid uneven gasket load, and helps to prevent leak, also helps to avoid the damage of the flange or even the possibility of cracks. When connecting flange and valve flange material is different, this kind of preventive measures is particularly important. Pneumatic pneumatic control valve installed on the upstream and downstream of the pressure tube will help to check the flow or pressure drop. Will bring pressure pipe received from bend, reducing or hole diameter of straight pipe. This position can be due to fluid turbulent flow to minimize the inaccuracy. With a quarter or 3/8 of an inch ( 6 - 10毫米) Tube put pressure on the actuator interface connected to the controller. Keep the short distance connection, and try to reduce the number of pipe fittings and elbow in order to reduce the system time lag. If the distance must be very long, so can be used on pneumatic pneumatic - valve a locator or supercharger.
