PTFE Pilot Diaphragm Valve Normally Closed Corrosion Resistant For Chemicals Acid
Benefits Of PTFE Solenoid Valve:
The PTFE Solenoid valve is a special type of valve specifically designed to cope with extreme chemical corrosion environments and ultra-high purity requirements. It utilizes the nearly perfect chemical inertness, thermal resistance, non-stickiness and high purity characteristics of PTFE materials, and is widely used in key industrial sectors such as chemical engineering, pharmaceuticals, environmental protection, and semiconductors.
Features Of 5MPa Solenoid Valve :
1).The key components such as the valve body, valve cover, valve core and valve stem are all made of PTFE, which can withstand strong corrosive media such as 98% concentrated sulfuric acid and aqua regia.
2).The surface is extremely smooth, hardly adhering or accumulating any materials or deposits. It is easy to clean and has excellent thermal stability as well as good electrical insulation properties.
3).Direct or pilot-type structure, with quick opening and closing, excellent sealing performance and long service life.
4).Can choose plastic type ,explosion-proof energy-saving.
