Stainless Steel Sanitary PTFE Welded Angle Seat Valve

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.

Options for stainless steel sanitary welded angle seat valves include:

Valve body material: 304 stainless steel, 316L stainless steel

Seal material: PTFE, EPDM, FKM

Actuator material: stainless steel, engineering plastics

Control mode: normally open, normally closed, double acting

Connection method: welding, quick-install (quick-install adapter), thread

Surface treatment: mirror polishing, electrolytic polishing, sandblasting

Protection level: ordinary type, waterproof type (IP65/IP67)

Operation mode: pneumatic control, manual control, electric control

Special applications: anti-corrosion type, high temperature type, low temperature type

• 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.

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.
