As the core component of a fluid control system, the quality of its installation directly affects the operating efficiency, safety and service life of the system.
During the actual installation process, various errors are prone to occur due to improper operation, insufficient technical knowledge or inadequate control of details, which may not only lead to leakage, increased energy consumption and other problems, but also cause equipment damage and safety accidents in serious cases.

304, 304L, 316 and 316L are stainless steel grade codes in the American material standard (ANSI or ASTM), belonging to the 300 series of austenitic stainless steel. The corresponding grades in the domestic material standard (GB/T) are 06Cr19Ni10 (304), 022Cr19Ni10 (304L), 06Cr17Ni12Mo2 (316), 022Cr17Ni12Mo2 (316L). This type of stainless steel is usually referred to as 18-8 stainless steel.

Which is better, forged steel valves or cast steel valves?
Cast steel valves are made of steel used for casting. They are a type of cast alloy. Cast steel is categorized into three types: cast carbon steel, cast low-alloy steel, and cast specialty steel. Cast steel refers to a type of steel casting produced by the casting process. Cast steel is primarily used to manufacture parts with complex shapes that are difficult to forge or machine, yet require high strength and ductility.
Forged steel refers to various forgings and forgings produced by the forging process. Forged steel parts are of higher quality than cast steel parts and can withstand high impact forces. They also have higher ductility, toughness, and other mechanical properties than cast steel parts. Therefore, forged steel parts should be used for all important machine parts.

An electric actuator primarily consists of a power board, main board, travel detection device, torque measurement device, AC contactor or frequency converter, motor, and reducer. An electric actuator uses a small motor to drive a worm gear in a first-stage reduction mechanism, capable of delivering multi-turn, angular, or linear motion to the valve. The actuator's motion output is determined by the characteristics of the valve being controlled.

This regulation applies to the setting of gate valves, stop valves, ball valves, butterfly valves and pressure reducing valves in petrochemical plants. The setting of check valves, safety valves, regulating valves and steam traps shall refer to the relevant regulations. This regulation does not apply to the setting of valves on underground water supply and drainage pipes.

Model and specification verification
Confirm that the type of check valve (such as lift type, swing type, butterfly type, etc.), nominal diameter, pressure level and pipeline system match to avoid leakage or failure due to specification mismatch.
