What is ptfe needle valve ?

The PTFE Needle Valve is designed for laboratory and industrial applications for regulating corrosive gases and liquids for high purity services so that the media only come in contact with PTFE and PCTFE. PTFE needle valve spindles are made of ridged PCTFE to minimize creeping associated with PTFE. PTFE used in PTFE needle valve seals stands for Poly-Tetra-Fluoro-Ethylene, which is the chemical term for the polymer (CF2)n.Poly-tetra-fluoro-ethylene (PTFE) is a thermoplastic member of the fluoropolymer family of plastics and has a low coefficient of friction, excellent insulating properties

The Teflon needle valves are designed for relatively high flow ranges while still performing well in low flow rates. Valves may be used in pressure or non-critical vacuum service. The simplicity of design there are only seven components assures reliability and minimizes sources of leakage. It takes seconds to disassemble the Isolation Needle Valves for cleaning and maintenance. ,

Easily dissolved by fuming sulfuric acid, high temperature sulfuric acid, or caustic soda above 100oC; also bloats or dissolves when interacting with strong solvents such as aceton、ketone、DMA, or extremely alkalic primary amine such as n-butylamine.

    ASME ptfe needle valve Applications

High Precision PTFE Needle Valves Used in liquid, gas, or vacuum systems. Can be used to replace stopcocks and give precise needle-valve flow control. 2.0mm bore valve accepts removable glass tubes, facilitating its inclusion in apparatus being prepared by a glassblower. The straight connecting tube is sold separately.

PTFE lined needle valve distributors offer valves in three conveniently overlapping flow ranges. Safety handle prevents over tightening and facilitates fine-metered regulation. PTFE needle valve plug are useful in regulating the flow of corrosive gases and liquids. They may be used in pressure or non-critical vacuum service and serve as bubble tight shutoff valves.
