Application of stainless steel valves in the industry

Stainless steel valves refer to valves with a body material of stainless steel. Due to their excellent resistance to rust and corrosion, they are widely used in various industries, as follows: 1、 Food industry Stainless steel valves are widely used in production lines of food industry, such as biscuits, instant noodles and Rice noodles production lines, as well as dehydration line equipment for quick frozen food. These valves can ensure hygiene and safety during the food production process, while also meeting the requirements of convection

Installation process and precautions for ball valves

Preparation before installation Check the ball valve and related accessories Appearance inspection: Check the surface of the ball valve body, stem, seat and other components for cracks, sand holes, scratches, rust and other defects. The sealing surface of the valve body connecting flange should be flat and smooth, without radial grooves or other damages that may affect the sealing. For example, if deep scratches are found on the surface of the valve body, it may cause medium leakage during use, affecting the normal sealing performance of the ball valve. Specification verification: Carefully verify whether the model and specifications of the ball valve (such as nominal diameter, nominal pressure, connection method, etc.) are consistent with the design requirements. At the same time, check whether the material of the ball valve meets the characteristics of the medium used. For example, when transporting corrosive media, the material of the ball valve should have corresponding corrosion resistance. For example, for media containing hydrochloric acid, stainless steel ball valves are usually used. Accessory integrity check: Confirm that the bolts, nuts, washers, and other accessories required for the installation of the ball valve are complete and free from damage, deformation, etc

What are the types of actuators for pneumatic ball valves

The actuators of pneumatic ball valves are mainly divided into two types: single acting pneumatic actuators and double acting pneumatic actuators. The specific introduction is as follows: 1. Single acting pneumatic actuator Working principle: The cylinder is equipped with a reset spring, and the air source pressure enters the cylinder through an electromagnetic valve to push the piston to move, while compressing the spring to store energy. After the solenoid valve releases the cylinder pressure, the spring pushes the piston to reset, driving the ball valve core to automatically reset and maintain an open or closed state. characteristic:
