Stainless Steel Sanitary PTFE Welded Angle Seat Valve
The design purpose of the stainless steel sanitary welded angle seat valve is not only to control the opening and closing of fluids, but also to provide a stable, low-resistance, and high-life fluid regulation solution in a high-cleanliness environment. Traditional valves are prone to leakage due to seal wear when they are frequently opened and closed, while welded angle seat valves optimize the flow channel structure, reduce turbulence and flow resistance, and make fluid delivery smoother. In addition, its valve stem adopts a self-lubricating design to ensure that it remains flexible after long-term use and avoids the problem of jamming caused by frequent opening and closing. In high temperature and high pressure environments such as CIP/SIP cleaning or steam sterilization, welded angle seat valves can provide higher sealing reliability and avoid residual liquid from contaminating the pipeline system. At the same time, its welding connection method eliminates the dead corners and liquid accumulation points that may be caused by threaded or flange interfaces, further improving the hygiene level and ensuring the aseptic production requirements of the food, pharmaceutical and bioengineering industries.
Working Principles
The stainless steel sanitary welded angle seat valve relies on pneumatic or manual drive to control the rise and fall of the valve stem to achieve fluid opening and closing and flow regulation. In the initial state, the normally open valve remains open when there is no control signal, while the normally closed valve is in a closed state. When the air source or manual operation acts on the valve, the piston drives the valve stem to move up or down, causing the seal to separate or fit with the valve seat, thereby opening or closing the fluid channel. Due to its 45° inclined flow channel design, it can reduce fluid resistance, increase flow rate, and effectively prevent liquid retention when opened.

Features
● The stainless steel sanitary welded angle seat valve adopts a special valve body design that opens upward, which can effectively reduce the water hammer effect caused by rapid closing and protect pipelines and equipment.
● The valve cavity design of the stainless steel sanitary welded angle seat valve has been optimized by computational fluid dynamics, so that the liquid can be discharged naturally when closed, avoiding the retention of liquid residue and improving the hygiene level.
● The stainless steel sanitary welded angle seat valve adopts a special self-lubricating coating stem sealing technology, which can reduce wear and reduce maintenance frequency even under high-frequency opening and closing conditions.
● The pneumatic actuator of the stainless steel sanitary welded angle seat valve adopts a detachable modular structure, which can quickly replace the cylinder assembly or upgrade to electric drive to improve maintenance convenience.
● The stainless steel sanitary welded angle seat valve can accurately control the flow when the valve is opened through an optional manual fine-tuning mechanism, which is suitable for precision mixing and proportioning processes.
● The stainless steel sanitary welded angle seat valve adopts a sealing ring embedded fixed structure. Compared with the traditional card-embedded design, it can avoid the displacement of the sealing ring due to pressure shock or high-temperature expansion and improve durability.
Application
Stainless steel sanitary welded angle seat valves are widely used in the following industries: Food industry: used for fluid delivery of beverages, dairy products, condiments, etc., to ensure high hygiene standards. Pharmaceutical industry: suitable for medium transmission such as liquid medicine, vaccines, sterile water, etc., to meet GMP requirements. Bioengineering: used for high-cleanliness fluid control such as cell culture fluid and culture medium. Cosmetic industry: transport emulsions, essences and other products to ensure no pollution and high purity. Chemical industry: handle corrosive chemicals and high-purity solvents, with strong corrosion resistance. Semiconductor industry: used for ultrapure water and high-purity gas delivery to meet clean room requirements.
