Choosing the right type of constructive reinforcement largely determines the trouble-free operation as an autonomous technology industry as a whole and individual pipelines. Requirements for Taco mixing valves are extremely diverse. However, the apparent trend of a sharp increase in service life, reliability and durability of all types of Taco valves. Valves linear part of the pipeline should have longevity of about 10-20 years, as the replacement cost of such valves is more expensive cost of the heating valves because of the need to stop the gas pipeline, the complexity of delivery of the PEX fittings in place, etc.
Valves technological pipelines refineries and petrochemical plants in operation in a variety of modes and conditions. The general requirements for such a fixture, usually in these cases are explosion-proof (especially when it relates to the electric drive and magnetics), tightness of the bolt, gasket and seals, corrosion resistance of the material of main parts, sealing resistance to hydrocarbon media. The design of fixtures must also meet the requirement of high suitability for repair – light and easy replacement of worn parts. These same requirements apply when using valves to aggressive environments.
Type and purpose of the pipeline, durability and maintainability, reliability, and the type of reinforcement and its place in the hydraulic system determines the specific features of the application and operation of valves as well as the nature of the requirements for it. Finally, one of the decisive factors when using an economical valve.
This should take into account the price of reinforcement, the cost of its services, as well as the influence of reinforcement on the economic performance of the entire process. All these characteristics have to be necessarily associated with an estimated life of the system, where applicable PEX fittings, as well as projected future modernization or automation.
Thus, summing up one can say that the valves should be selected according to:
1) the specific conditions and characteristics of the technological process, in which she must participate;
2) the type and physical properties of the working medium (oil, water, gas, steam and others);
3) the nature of reinforcement (frequency response, the vast open or closed) position;
4) type of loads in the hydraulic system (stable mode, pulse pressure, dynamic and impact loads, the presence of vibration);
5) temperature of the pipeline and the environment.
