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.

• Options: With flow rate adjustment, with indicator, with by-pass, high back pressure (0.5 MPa) tolerant, Low water hammer type, body wetted parts equivalent to EP grade.

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.

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.

If you need a 2 port air operated valve for use with aggressive fluids then look no further than our new Series LVP. Developed specifically for use with deionized water and harsh chemicals such as hydrochloric acid and hydrogen peroxide, our R&D engineers have designed this multi-purpose valve with a vinyl chloride (CPVC) body and a PTFE diaphragm. Suitable for use in many industrial applications including clean in place (CIP) systems, electro plating and metal finishing, water treatment and PCB manufacturing, Series LVP offers further performance benefits including simple flow rate adjustment and dramatically reduced low water hammer – 50% lower than conventional fluid valves. With the possibility of piping from four directions and a PVC unfixed union to accommodate a rigid vinyl chloride tube, these new LVP valves deliver impressive operational performance when working with a large range of aggressive or corrosive fluids.

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.

Semiconductor and LCD manufacturers now have a perfect pump solution with the launch of the new PAF diaphragm pump from SMC. Designed specifically to meet industry demands, this high performance fluororesin pump is constructed with non metallic body parts to ensure perfect compatibility when using high purity chemicals.With all wetted parts made from either new PFA or PTFE, the PAF´s premium chemical and temperature characteristics are further enhanced with use of PFA-PPS dual construction to improve both proof pressure and heat cycle performance.Currently available in two options, an automatically operated type with a solenoid valve built into the pump body or an air operated type where the valve and electrical circuit are separated from the pump, the PAF offers a lightweight, compact, high flow rate solution to meet the most demanding of needs. Additional features include the option to include an optical leak detector which can provide an early warning signal of diaphragm failure and in the case of the air operated type, the addition of mounted optical stroke sensors to ensure stable operation of the pump and accurate cycle monitoring.

The PB series is a compact, single acting diaphragm pump which is suitable for transfer and recovery of a wide variety of fluids. The PB series is available with a built-in solenoid valve or in an air operated style. Space is saved due to the centralization of piping and wiring areas on the top and bottom surfaces.

The SRF30 series is designed to regulate DI water and N2 gas in the clean room. Fluoro resin material is used in the fluid contact area. The fluid contact area is washed with freon ultra sonic and DI water.

Machine builders requiring extra flexible, heat and chemical resistant tubing now have the answer with our new Series TD/TID tubing range. Developed specifically for use in restricted space applications, this soft multi-purpose fluoropolymer tubing achieves a 20% increase in flexibility when compared to our existing TL/TH tubing. Available in both metric and inch sizes of between 4 -12 mm and 1/8" – 1/2" respectively, the tubing is made from denatured PTFE fluorine-based resin which provides high chemical and heat resistance up to + 260ºC. With Food Sanitation Approval (FDA), TD/TID is the perfect solution in Food and Packaging, Life Science, Semiconductor and Automotive industry applications.

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.
