This industry requires both IP65 safe area and ATEX hazardous area, SIL 3, UL, GOST R 2013, GOST K, Inmetro + CE solenoid valves for the control of compressed air, process gases and liquids from 1/8" to 3" thread or flange. This would include ATEX classifications Zone 21 & 22 EExm II 2 G/D IIC T4 protection by encapsulation, EEx d IIC T6 explosion proof protection by encasement and EEx ia IICT6 intrinsically safe with low voltage protection.Throughout history, valves of one type or another have been used to control and regulate the flow of water. Today, the water industry demands quality solenoid and pressure control valves that are both dedicated to the control of water and built using the very latest technology.Brass, stainless steel and plastic valves range from compact 1/8" threaded units through to 3" thread or DN10 to DN1000 PN16 or ANSi150Lb flange in either 2/2 (2 port 2 position) or 3/2 way normally open; closed & universal (diverting) function either normally open ...
