The FVLT100 Series compact and reliable PTFE needle valves are designed for laboratory and industrial applications for regulating corrosive gases and liquids or for high purity service. They may also be used as shut off valves.

Structurally rigid metallic shells reinforce the PTFE bodies of the valves. Fluids contact only PTFE and CTFE materials. Shells are made of anodized aluminum or type 316 stainless steel and bushings are made of plated brass or 316 stainless steel. Where externally corrosive conditions exist stainless steel is recommended. Valve spindles are made of rigid CTFE to minimize the undesirable material “creeping” normally associated with PTFE.

The FVLT100 Series PTFE 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 (including a single PTFE o-ring) - assures reliability and minimizes sources of leakage. It takes seconds to disassemble the valve for cleaning and maintenance. The PTFE o-ring is radially compressed and due to this unique design feature the degree of compression may be adjusted without disassembly by tightening the hexagonal bushing.

The FVLT110 Series Metering valves are constructed of PTFE and PCTFE materials. Non-fluid contacting external parts are made of anodized aluminum.

Valves are offered in three conveniently overlapping flow ranges. Safety handle prevents over tightening and facilitates fine-metered regulation. FVLT110 Series valves 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.
