Create separation between the solenoid and fluid. Available with inert materials of construction, such as PEEK and FFKM to handle aggressive chemicals or high purity media. 3/2 normally closed construction Rocker isolation Pad mount 0.060" orifice Up to 35psi 4.0 Watt ~20ms response time Meets CE directives

The 8396 Series is a 3-Way, high flow isolation valve designed to control the flow of aggressive liquids and gases in analytical, semiconductor, and environmental equipment. The 8396 Series offers the following benefits: reliable operation with a wide variety of media due to inert wetted materials such as PEEK, PTFE, stainless steel, and FFKM. High flow rates of corrosive or high purity fluids. Higher pressure ratings than typical isolation valves. 3/2 normally closed construction Bellow isolation Inline mount 0.1.57" orifice Up to 44psi 11.2 Watt Meets CE directives  

The 067 Series is a 10mm wide, pad mount, rocker isolation valve designed to control the flow of aggressive chemicals or high purity fluids. The Series 067 offers the following benefits: Inert materials of construction, such as PEEK and FFKM Small internal volume Excellent flushability Self draining Power savings and reduced heat exchange due to special integrated electronics 2/2 normally closed & 3/2 universal constructions Rocker isolation Pad mount 0.024 to 0.053" orifice Vacuum to 44psi Low power, 2.5 Watt ~10ms response time Meets CE directives

The 067 Series is a 22mm wide, pad mount, flapper isolation valve designed to control the flow of neutral or aggressive fluids. The 067 Series offers the following benefits: Create separation between the solenoid and fluid Excellent self-draining capability and easy-to-flush internal cavity "Flapper" mechanism yields no pumping or sticking effect 2/2 normally closed & 3/2 universal constructions Flapper isolation Pad mount 0.079 to 0.157" orifice Vacuum to 145psi 10.0 Watt ~10ms response time Meets CE directives
