Chemical Liquid Valves and Accessories

SMC high purity HYPER FITTING series LQ* responds to the latest demands in process control. From parts cleaning to assembly and packaging, all processes are controlled for cleanliness, and the use of new PFA virtually eliminates particle generation and TOC (total organic carbon) allowing confident use for the most demanding applications. If chemistries or flow requirements are changed duing process, our face seal design allows for quick change of tubing, and/or tube diameters, using the same fitting body.

SMC high purity series LVA valve has three types of body materials (SUS/PPS/PFA) that can be selected based on the customer's application. Special diaphragm construction insures gentle opening and closing that prevents the formation of micro-bubbles. A unique guide ring on the piston rod eliminates lateral motion of the poppet, greatly increasing seal life and reducing particle formation.

High purity chemical valves, series LVC with integral fittings eliminate the possibility of residual liquid in pipe threads. In addition, the body has been designed for smooth flow with minimal internal dead space. Special diaphragm construction insures gentle opening and closing preventing the formation of micro-bubbles. A unique guide ring on the piston rod eliminates lateral motion of the poppet, increasing seal life and reducing particle formation.

LVH series air operated high purity valves are corrosion resistant against acid, alkali and ultra pure water, making the LVH valve the perfect answer to overcome the harsh environments often encountered in wet process applications. Series LVH is a manually operated valve, available in a threaded or integral fitting type.

Series LVM is a compact, direct acting, 2/3 port solenoid valve for chemicals. The unique construction reduces residual liquid to a minimum. Superior resistance to chemicals requires less maintenance. Service life (based on SMC test conditions) is 10 million cycles or more.

An complaint often heard in both semiconductor and chemical equipment industries, is that it's almost impossible to eliminate bubble formation in the fluid circuit during the manufacturing process. Following extensive research and development, engineers from SMC, the worlds leading automation control experts, are pleased to announce that this is no longer the case with the introduction of their latest chemical needle valves – Series LVN.Developed especially to overcome bubble generation when using light liquids, LVN valves are manufactured from a new type of lightweight PFA material which is highly compatible with acids, bases and ultra pure water. Normally installed on top of the filter unit, these needle valves can regulate flow rates between 0 to 12 l/min and when used in conjunction with SMC's LQ2 hyper PFA fittings, with their unique quadruple seal construction, outstanding performance is achieved providing minimal leakage, reduced residual fluid and high flexural strength.Series LVN valves are the perfect answer when working with fluids between 5 – 90º C, at operating pressures of 0 – 0 ,5 MPa and in ambient temperatures of 0 – 60º C - a champagne solution minus the bubbles.

Series LVP, employs vinyl chloride CPVC for body material.  With its 2 ports, piping is possible in four directions.  Applicable fluids, deionized water and chemicals.

Series LVQ is a 2 port chemical valve with a non-metallic exterior. A high density PVDF housing offers increased chemical resistance and the special diaphragm construction insures gentle opening and closing preventing the formation of micro-bubbles. The LVQ guide ring eliminates lateral motion of the poppet, which reduces internal leakage.

TD/TID series is a highly flexible fluorine resin tubing that was designed for installation in small spaces. The denatured PTFE fluorine resin tubing was developed to realize high flexibility, while maintaining the same heat and chemical resistance as the series, TL/TH. TD/TID series is suitable for industries that require heat and chemical resistance and conforms to Food Sanitation Law.

Series TIL high purity fluoropolymer tubing is available as standard in inch sizes of 50' and 100' rolls. The TIL series has outstanding corrosion resistance, compatible with chemicals such as acids, bases and ultrapure water. The TIL series is also compatible with maximum fluid temperatures of up to 200°C.

We are pleased to unveil a new advanced flexible, heat and chemical resistant tubing that is chemically compatible with a wide range of fluids and can resist temperatures up to 260°C. The TLM features improved PFA material, which allows use in applications requiring chemical resistance and can withstand fluids that need to be conducted at very high temperatures. It also comes in four different colours – red, black, blue and translucent – so customers can set differently coloured tubes in a visual way to help ease the maintenance and calibration works process, which is required periodically. What is more, we have extended the size and length variations so customers can select exactly what they need in 13 metric and 9 inch options. It can also be ordered in seven different lengths from 2 metres straight up to 100 metre rolls. Developed to be combined with our extensive specific Fittings Series, the addition of the TLM tube provides customers with a complete solution for their piping equipment needs in one single step.

Series TL high purity fluoropolymer tubing is available as standard in metric sizes of 10m or 20m rolls. The TL series has outstanding corrosion resistance, compatible with chemicals such as acids, bases and ultrapure water.
