Applications of API 609 Butterfly Valves in the Petroleum and Chemical Industries..
Yuming Valve API 609 standard butterfly valves (including double-eccentric and triple-eccentric structures) are the preferred valves for large-diameter, low-pressure to medium-pressure applications in the petroleum and chemical industries due to their compact structure, low flow resistance, and flexible opening and closing.

API Ball Valves: Harsh Working Conditions of Chemical Plant..
Yuming company's API 6D standard ball valves are also used throughout the entire process of exploration, extraction, gathering, transportation, and refining in the oil industry. They have become core valves suitable for harsh working conditions such as high pressure, high sulfur content, and high impurities.
Must check valves be installed horizontally or vertically?..
A check valve, as a type of valve that automatically opens and closes its disc based on the flow of the medium itself, has the core function of preventing backflow and ensuring the process safety and operational efficiency of the pipeline system. Regarding whether its installation direction must be horizontal or vertical, the answer is not singular, but rather determined by the specific structural design and working principle of the valve.

Pressure Regulating Steps and Main Functions of a Pressure Regulator..
The core function of a pressure reducing valve is to stabilize upstream high pressure to the required downstream low pressure, while protecting downstream pipelines and equipment. Pressure regulation must follow an orderly procedure of "preparation-adjustment-verification-locking".

Basic Principles of Valve Sealing Surface Grinding..
The basic principle of valve sealing surface grinding is to eliminate microscopic defects such as unevenness, scratches, and corrosion on the sealing surface through mechanical friction and material removal, achieving a highly flat, smooth surface that fits tightly against the mating sealing surface. This ensures the valve effectively prevents media leakage when closed.

【Valve Knowledge】 The Role of Control Valves in Pipelines..
Control valves are core control components in pipeline systems. Their core function is to precisely regulate key parameters of the medium (liquid, gas, steam, etc.) within the pipeline by changing the flow area between the valve core and seat, thus meeting the process requirements and stable operation needs of industrial production, energy supply, water treatment, and other scenarios.

【Valve Knowledge】Common Materials for Valve Bodies..
Metal materials are the core choice for valve bodies due to their high strength and good pressure resistance. According to the material properties, they can be divided into cast iron, cast steel, stainless steel, non-ferrous metals and corrosion-resistant alloys.

Why might a valve fail to open after being closed for an extended period?..
The key reason a valve fails to open after being closed for an extended period is that, due to the media and environmental influences, the valve's internal components undergo physical or chemical changes during prolonged static operation. This can cause moving parts (such as the valve stem, gate, and ball) to become stuck or locked, preventing them from operating normally.
