Valve fittings and matching flanges, nuts (120%), nuts (120%), gaskets (200%). It is necessary that the material of the mating flange is completely consistent with the material of the process pipe to facilitate welding during site construction. The signs and each valve shall be of stainless steel, shall be in an easy to observe orientation and shall include the following.
The name of the manufacturer, the position number, production number and type of the valve, the material, scale and pressure grade of the valve body shall be selected according to the medium supplied on site, flow rate, pressure, temperature, viscosity, process pipe diameter and other parameters after the valve is issued, which shall be calculated by the original software of the original manufacturer and fully meet the requirements of the plan. Regarding the actuator, the selection of the actuator should be based on the climate and conditions of various places.
The southern region of our country can choose the ordinary type of performance arrangement, and on the northern alpine region must choose the low temperature type of performance arrangement, on the environment temperature for a long time in the high temperature operation of the control valve should choose the high temperature type of performance arrangement. The performance arrangement for low temperature type, the connecting bracket selection of low temperature resistant cast steel, diaphragm, 0 type ring and other rubber parts are used low temperature resistant materials, smooth with smooth grease also with low temperature resistant smooth grease.
Fulfillment arrangement is now multi-spring structure, which is characterized by light weight, small size, high function and large output force. Pneumatic arrangement and the choice of control valve type, scale, etc.; large diameter control valve, the use of multi-spring diaphragm structure. About Annex 1, electrical valve positioner should receive 4~20mADC analog signal.
