PTFE rubber seal is a seal made of polytetrafluoroethylene (PTFE). PTFE is a synthetic material with excellent chemical stability and low friction properties that is used in a wide range of industrial fields.
Membranventile benötigen keine separate Stopfbuchsabdichtung, da die Membran das Medium gleichzeitig abschneidet, um die Ventilstange abzudichten. Und die flexible Membrane lässt sich zuverlässig schließen, und auch die verschmutzte Flüssigkeit kann gut abgeschnitten werden. Daher sind der Steuermechanismus und der Medienkanal vollständig getrennt, so dass das Membranventil nicht nur in der Lebensmittelindustrie und der Medizin- und Gesundheitsindustrie, sondern auch für einige schwer zu transportierende und gefährliche Medien eingesetzt werden kann.
PTFE Rotary Oil Seal for Gearboxes is a polytetrafluoroethylene rotary oil seal for gearboxes. The transmission case is a common component in mechanical equipment used to transmit power and speed, and PTFE Rotary Oil Seal is used to protect the oil lubrication system in the transmission case and prevent external impurities from entering the interior of the transmission case.
Dual plate check valve sealing rings are sealing elements used in double plate check valves. Their main function is to provide sealing between the two halves of the valve (i.e. double plates) to ensure that the valve prevents backflow of the medium when it is closed. These seals are usually located between the two contact halves of the valve. When the valve is closed, the seals are under pressure and deform, filling any tiny gaps to form an effective sealing interface.
Piston T-Seals refers to the seal between the cylinder and the piston. A poor seal can affect the performance of the cylinder. The seal groove is placed on the piston. The piston seal is the main seal in the hydraulic cylinder, and the pressure is bidirectional. Piston seal belongs to reciprocating seal, it is one of the key components in hydraulic equipment. Leaking pistons can cause operational problems and environmental pollution.
PTFE Piston Static Seal Energized by Spring is a type of sealing solution that is used in hydraulic and pneumatic systems. It consists of a PTFE (polytetrafluoroethylene) piston ring that is energized by a spring. The PTFE material provides excellent resistance to high temperatures and corrosive chemicals, making it a popular choice for critical applications.
PTFE Filled Glass Flange Gaskets are a special type of gasket consisting of polytetrafluoroethylene (PTFE) and fiberglass-filled materials. It is mainly used to seal pipes, containers and flange connections to prevent media leakage. They are commonly used in chemical, petroleum, pharmaceutical and food industries, especially where corrosive media and high temperature environments are involved.
The Q Seal ring is designed for dynamic sealing applications. Combines the low friction properties of a typical PTFE cap seal with the sealing performance of an O-ring. The sealing ring has a small-section, petal-shaped O-ring on the sealing surface to reduce leakage. This seal can be used in applications where two different fluids need to be separated (fluids or gases);
Teflon-Federkraft-Wellendichtungen werden häufig in Industriebereichen eingesetzt, in denen hochzuverlässige Wellendichtungen erforderlich sind, wie z. B. in der Petrochemie, Pharmazie, Lebensmittelverarbeitung, Luft- und Raumfahrt usw. Sie spielen eine wichtige Rolle bei der Verhinderung von Flüssigkeitslecks und Verunreinigungen, bei der Reduzierung von Reibung und Verschleiß und bei der Verlängerung der Lebensdauer von Anlagen.
PTFE Filled Carbon Washers are widely used in various industrial fields such as chemicals, oil and gas, pharmaceuticals, food processing, etc. They are commonly used in valves, pipes, pumps and other equipment to provide sealing and reduce friction while being resistant to chemical corrosion and high temperature environments.
PTFE rubber seals have excellent corrosion resistance to most chemicals, including acids, alkalis, solvents, etc. They maintain sealing performance in harsh chemical environments.
PTFE rubber seals have an extremely low coefficient of friction, making them excellent in dynamic sealing applications. They reduce energy losses, reduce friction and wear, and increase seal life.
PTFE rubber seals maintain good performance over a wide temperature range. They are able to withstand extremely low temperatures to -200°C and high temperatures to +260°C.
PTFE rubber seals have excellent compression elasticity and resilience, providing reliable high-pressure sealing performance. They are widely used in equipment such as high-pressure pipelines, valves and pumps.
