VALVES 2 VAL-321 For further information www.norgren.com We offer standard-sized body orifices from 1/32" to 5/32" for KIP Series 1 through 6. Series 3 and 6 orifices are also available up to 1/4". We also offer a 3/8" body orifice in Series 6. Standard end stop (top of valve) orifice sizes are available from 1/32" to 1/16" in Series 1. Seals Seal materials 01 Buna - N A general purpose, soft, synthetic rubber suitable for most air, non-potable water and light oil environments with temperatures to 200° F. 02 Fluorocarbon A soft, fluorocarbon rubber used primarily with hydrocarbon liquids such as gasoline, aerospace fuels, solvents, etc., which can cause swelling and distortion to Buna. Fluorocarbon is also used for oxygen service. The material is appropriate for higher temperature ranges, and is more resistant to "dry" heat. 03 Standard Neoprene A sofe, synthetic rubber with excellent low temperature sealing and very good heat aging resistance. 05 Low Temperature Buna Primarily used in low temperature applications down to -40° F/C. Suitable for most air, non-potable water, and light oil environments. 06 Polyurethane Primarily used for high load applications involving non-corrosive gases & oils. Especially good for high pressure gases prone to absorption such as CO2. Not recommended for water, acids or chlorinated solvents. Up to 5/64" in KIP Series 2 and 3 valves and up to 1/8" in Series 6 valves. In addition, we offer larger end stop orifices on all Series 1, 2 & 3 to maximize flow. However, these orifices are application-sensitive. Please consult technical support for assistance. All orifices are precision machined to guarantee sealing surface finish and height for improved repeatability and reliability. 08 PTFE A synthetic material used in corrosive and semi-corrosive media. Teflon is virtually impervious to any fluid. Its ability to withstand high temperatures makes it especially suited for use with steam. However, it is not recommended for vacuum applications. 12 Neoprene W A soft, synthetic rubber that is used primarily for refrigerants, especially R-12 and R-22 with oil. The material has excellent dynamic sealing capabilities. Also characte- ristic of this material is improved fluid resistance and lower swell. 13 Ethylene Propylene (EPR) Food Grade A soft, synthetic rubber ideal for beverages, potable water and steam, (where steam pressure is below 50 PSI). Suitable for steam and hot water where temperatures are above Buna's tolerances. EPR is not appropriate for petroleum liquids or petroleum-contaminated air. It is compatible with automotive brake fluids and phosphate ester synthetic oil. All KIP Series valves are supplied with spring compensated upper seals, lower seals and "O" Rings. Both upper and lower seals are also available in several different materials. Consult technical support for temperature limits, durometer ratings, minimum order quantities or requirements for other sealing materials. Orifice KIP Solenoid Valves Standard valve selection
