Product Description
Design and manufacture standard
API stainless steel gate valves are designed and manufactured in accordance with API 603 and other relevant standards. The structural length and other dimensions are required to be performed in accordance with ASME B16.10 standards, and the flange ends are tested in accordance with ASME B16.5 standards.
Main components and materials
Valve body and valve cover: usually ASTM A351 and other standard materials, with good strength and corrosion resistance, can withstand the pressure in the pipeline and the erosion of the medium.
Ram: Generally also made of suitable stainless steel materials such as ASTM A351, to ensure its wear resistance and corrosion resistance during opening and closing to ensure the sealing performance of the valve.
Valve stem: ASTM A965 and other materials are often used, with sufficient strength and toughness, and can transmit torque stably during operation to achieve accurate opening and closing of the ram.
Valve seat sealing ring: More materials with good sealing performance and corrosion resistance, such as PTFE, are used to ensure the tightness of the valve in the closed state and prevent media leakage.
Peculiarity
Strong corrosion resistance: The use of stainless steel, such as the common 304, 316, 316L and other stainless steel, has good corrosion resistance to oxidizing acid media, and can operate stably in different corrosive environments for a long time to reduce maintenance costs and replacement frequency.
Small fluid resistance: When the medium flows through the stainless steel gate valve, it does not change its flow direction, and there is basically no turbulent flow phenomenon, so the fluid resistance is small, which helps to reduce the energy loss of the pipeline system and improve the operating efficiency of the system.
Small opening and closing torque: the direction of the gate movement is perpendicular to the direction of the flow of the medium, compared with some other valves, the opening and closing torque is smaller, less labor to open and close, and the operation is more convenient, especially in large diameter valves or high-pressure differential conditions, which can better reflect this advantage.
Unrestricted flow direction: the medium flow direction is not restricted, can flow from both sides of the gate valve in any direction, can achieve the purpose of use, especially suitable for the medium flow direction may change in the pipeline, increasing the flexibility and adaptability of the pipeline system.
Compact structure: The gate is placed vertically in the body, the structural length is shorter, and the API stainless steel gate valve takes up less space than some other types of valves at the same nominal diameter, facilitating the installation and layout of piping systems in space-limited locations.
Good sealing performance: the sealing surface is less eroded when fully opened, and can achieve reliable sealing in the closed state, effectively prevent medium leakage, ensure the safe operation of the pipeline system, and reduce environmental pollution and production accidents that may be caused by leakage.
Apply
API stainless steel gate valves are widely used in many industries, such as oil and gas industry, for oil and gas transmission pipelines, wellhead devices, etc., can withstand high pressure, high temperature and corrosive media; In the field of petrochemical industry, it can be used in the transportation pipelines of various chemical raw materials and products, such as the process pipelines of refineries and chemical plants; In the power industry, it can be used in the transmission system of steam, water and other media, such as steam pipes and cooling water pipes of power stations; It can also be used in pharmaceutical, food and beverage and other industries with high health requirements, and its stainless steel material meets health standards, which can ensure the purity and safety of the media.
