Fluorine lined gate valve advantages overview:

1, the fluid resistance is small, sealing surface by media brush and erosion is small. 2, open and close less effort. 3, the medium flow is not restricted, no turbulence, no pressure reduction. 4, the shape is simple, the structure is short, the manufacturing process is good, the application range is wide.

The materials used are as follows:

Polytetrachloroethylene PTFE(F4) using medium: strong acid, strong base, strong oxidant, etc. Use temperature: -200~180 Features: excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, is an excellent self-lubricating material, but the mechanical performance is low, poor liquidity, thermal expansion. Polyvinylidene chloride PVDF(F2) use medium: resistance to most chemicals and solvents, use temperature: -70~100 Characteristics: pull and compression strength is better than F4, bending resistance, weather resistance, radiation resistance. Light resistance and aging, the biggest special point is good toughness, easy to form. Polyolefin: PO Applicable media: various concentrations of acid, alkali and some organic solvents. Use temperature: -58~80 Features: is the world's most ideal anticorrosive material, has been widely used in rotary molding of large equipment and pipe lining. Polyperfluoroethylene FEP (F46) applicable media: any organic solvents or reagents, dilute or concentrated non-mechanical acids, bases, ketones, aromatics, chlorinated hydrocarbons, etc. Characteristics: Mechanical, electrical and chemical properties are basically the same as F4, but the outstanding advantages are high dynamic toughness, excellent weather resistance and radiation. Polytrifluoride PCTEF (F3) suitable medium: all kinds of organic solvents, inorganic corrosion liquid (oxidizing acid) use temperature: -195~120 Characteristics: heat resistance, electrical and chemical stability second only to F4, mechanical strength, creep performance, hardness than F4 better polypropylene: RPP suitable medium: Aqueous solution of inorganic salts, dilute or concentrated solution of inorganic acids and bases. Use temperature: -14~80 Features: one of the lightest plastics, its yield, tensile and compressive strength, hardness are better than low pressure polyethylene, has a very outstanding rigidity, good heat resistance, easy forming, good integrity. Dynamic properties, fluidity and flexural elasticity after modification. PVC applicable medium: water resistance, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc. Features: high mechanical strength, chemical stability and dielectric properties, oil resistance and aging resistance is also good, easy to weld and bond, low price.

Fluorine-lined gate valves of fluorine-lined valves have the following advantages:

Light weight: the body is made of advanced ball black cast iron, the weight is reduced by about 20%~30% compared with the traditional gate valve weight, easy installation and maintenance. Flat-bottom gate seat: the traditional gate valve is often in the water washing pipe after the accumulation of external objects such as stone, wood, cement, iron debris, debris and so on in the bottom groove of the valve, easy to cause can not close close and form water leakage phenomenon, elastic seat sealing gate valve bottom with the same flat design of pipe machine, not easy to cause debris deposition, so that the fluid is unimpeded. Integral rubber encapsulation: The ram adopts high-quality rubber for integral inner and outer rubber. The first-class rubber vulcanization technology in Europe enables the vulcanized ram to ensure the precise geometric size, and the rubber and ductile ink cast ram to be firm, not easy to fall off and good elastic memory. Water casting Valve body: The valve body adopts precision casting. The precise geometry allows the valve body to be sealed without any finishing work.
