Pneumatic control valve is usually are connected by a pneumatic actuator and control valve installation and debugging after the formation of the portfolio. Pneumatic control valve installation and debugging is very important, this article mainly introduces the pneumatic control Industrial Valves installation details and skills: A. The installation process should always comply with the pneumatic control valve installation instructions and pay attention to the point; B。 Working environment temperature regulator must be ( - 30 ~ + 60) Relative humidity is not more than 95% 95%, the relative humidity is not more than 95%; C。 position should have straight pipe before and after, the length is not less than 10 times the pipe diameter ( 10 d) To avoid the straight pipe is too short to affect flow characteristic; D。 Install valve in between, read the instruction manual. Products described in this instruction manual before installation and when installation should pay attention to safety issues and preventive measures; E. Confirm the pipeline cleaning: foreign body may damage valve sealing surface of pipe or even hinder the valve core, the ball or butterfly plate movement caused by the valve cannot be closed properly. In order to reduce the possibility of danger happens, need to clean all the pipe before install the valve. 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 the valve has a threaded 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 will result in the accumulation of valve core card plug or dirt, leading to can't normally closed valve; F。 We examined the regulator: 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; H。 Regulator shall be installed in horizontal pipe runs with them up and down and the vertical pipe, typically under the valve to support, to ensure stable and reliable. For special occasions, it is necessary to the regulator level when installed in a vertical pipe, also should be the regulator for support ( Except for small diameter regulator) 。 When installation, to avoid to bring additional stress to the regulating valve) ; G。 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. 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. Pneumatic control valve installed in storage when using the matters needing attention: A. This valve should be stored in dry room and must be blocked on both ends of the channel, are not allowed to be stacked tailings storage; B。 Long-term storage of the regulator should be checked regularly to remove dirt, in all the moving parts and processing surface should be coated with anti-rust oil, prevent rust; C。 This valve should be installed in horizontal pipe runs with required vertical installation, the Industrial Valves stem upward; D。 Required by this arrow and the medium for installation.
flanged gate valve are all following the most compatible manufacturing regulations.
Many websites provide additional information on the topic of ductile iron gate valve. One such site worth visiting is Mech Valve.
resilient seal gate valve needs not be tedious anymore with the application of . So getting the right wedge gate valve can drastically promote os & y valve fire protection.
