What Do You Think Of High Purity Plastic PTFE Solenoid Valves
High purity plastic valves and PTFE Solenoid values are made from PTFE, PVDF and other high purity plastics. These types of valves are produced by specialty plastic fabricator manufacturers for use in severe and critical service applications for the Pharmaceutical, Defense, Alternate Energy, Semiconductor, Medical and Chemical industries, to remotely control fluid flow. Since these products, including PTFE Solenoid Valves, are most often utilized in a corrosive laboratory environment or clean room automation environment, the high purity plastics of construction ensure the best results against corrosion and their chemical resistances offers long life within the application. Custom fluid control products made from polytetrafluoroethylene (PTFE) and other industrial plastics can be found in a wide variety of specifications to meet the many possible applications and can often be tailor-made to a customer's particular requirements.
PTFE Solenoid Valves are used to remotely control fluid flow. Their use is becoming increasingly popular in a wide variety of industrial applications thanks to their relative simplistic nature and affordable installation cost. With an enormous range of high purity plastic valves on the market, factories and plants throughout the industrial sector are easily able to find the right valve that meets the exact specifications of their intended use.
Solenoid valves are electrically actuated to either their open or closed position. The valve components work by allowing or restricting liquid flow depending on whether or not they are subject to an electrical current. The trigger device is normally an electromagnet coil which activates when fed an electric current, attracting a plunger or other valve stem component to changing the state of the mechanical device, this in turn allows or prevents liquid flow. When the electromagnet is deactivated, the plunger is returned to its original position typically by means of a return spring.
PTFE (polytetrafluoroethylene) is an industrial plastic useful for its chemical inertness and its high-purity properties, allowing it to perform well even under extreme temperatures, corrosive environments and within acidic fluids. The chemical resistance properties make PTFE a remarkably versatile polymer and therefore PTFE solenoid valves are commonly used in harsh industrial applications.
PVDF plastic (polyvinylidene fluoride) is another industrial polymer with excellent high purity, abrasion resistant, and chemical resistant properties. It is also available in FDA compliant grades. PVDF is a high tech plastic material from the fluoropolymer family and is typically used in applications and processes whose extreme conditions require the highest purity. PVDF high purity plastic valves are particularly suited to adverse conditions thanks to the material's strength, resistance to acids, bases, solvents and heat, as well as its property of low smoke generation in the event of a fire.
The sealing surfaces of typical High Purity Plastic and PTFE Solenoid Valves can be purchased in three different internal configurations; PTFE with Viton O-Rings, PTFE with Kalrez O-Rings, and an all PTFE wetted surface design. The valves are protected from the harsh industrial environment when in operation by long lasting, durable PTFE diaphragms, ensuring a long and reliable service life. Each of these PTFE Solenoid Valve types can be configured to fit various shapes, fittings, connections, power supplies and flow configurations or custom made to order from specialty plastic fabrication manufacturers.
