Proportional Valves

The Series 202 Posiflow  valves are 2-Way, normally closed, solenoid valves designed to proportionally control the flow of air or inert gases by varying the electrical input to the coil. They are available as stand alone valves with M5 thread ports or pad mount versions for manifold mounting. Ideal to precisely control flow rates in medical equipment and analytical instrumentation. Compact construction saves valuable space in equipment. Valves do not require minimum operating pressure Low hysteresis, excellent repeatability, and high sensitivity for precise flow control. 2/2 normally closed construction Pad & inline mount 0.031-0.079" orifice Vacuum to 174psi 3 Watt Hysteresis <5%, Repeatability <3%, Sensitivity <2% Meets CE directives

The Series 202 Preciflow valves are 2-Way, normally closed, solenoid valves designed to proportionally control the flow of air or inert gases by varying the electrical input to the coil. They are available as stand alone valves with M5 threaded ports. Ideal to precisely control flow rates in medical equipment and analytical instrumentation. Compact construction saves valuable space in equipment. Valves do not require minimum operating pressure Low hysteresis, excellent repeatability, and high sensitivity for precise flow control. 2/2 normally closed construction Pad & inline mount 0.004-0.079" orifice Vacuum to 145psi Low Power, 2.5 Watt Compact design Hysteresis <3%, Repeatability <1%, Sensitivity <1% Meets CE directives

The Series 202 PreciflowIPC (Inlet Pressure Compensated) valves are 2-Way, normally closed, solenoid valves designed to proportionally control the flow of air or inert gases by varying the electrical input to the coil. They are available as stand alone valves with cartridge or pad mount versions. Ideal to precisely control flow rates in medical equipment and analytical instrumentation. Compact construction saves valuable space in equipment. Valves do not require minimum operating pressure Low hysteresis, excellent repeatability, and high sensitivity for precise flow control. 2/2 normally closed construction Cartridge, pad & inline mount Inlet pressure compensated 0.118"orifice Up to 102psi Low power, 2.5 Watt Hysteresis <5%, Repeatability <1%, Sensitivity <1% Meets CE directives  

The Series 202 Posiflow  valves are 2-Way, normally closed, solenoid valves designed to proportionally control the flow of air, inert gases, water, or oil by varying the electrical input to the coil. They are available as stand alone valves with G1/8" thread ports. Ideal to precisely control flow rates in medical equipment and analytical instrumentation. Compact construction saves valuable space in equipment. Valves do not require minimum operating pressure Low hysteresis, excellent repeatability, and high sensitivity for precise flow control. 2/2 normally closed construction Inline mount with G1/8 threads 0.047-0.126" orifice Vacuum to 116psi 6.3 Watt Compact design Hysteresis <5%, Repeatability <1%, Sensitivity <1% Meets CE directives

The Series 451 are anodized aluminum manifolds used with ASCO!ˉs 411 & rB Series solenoid valves. The manifolds are available separately or as completed valve/manifold assembly. Valves easily thread into manifold, reducing assembly time, eliminating potential leak points, and avoiding plumbing errors associated with tubing together stand alone valves. Manifolds are constructed of corrosion resistant anodized aluminum. Standard manifolds feature 1/8 NPTF common port and descrete #10-32 ports to mate with metal or plastic fittings. ASCO offers complete manifold assemblies utilizing our 411 and RB Series valves. These assemblies consist of the valves mounted onto any anodized aluminum manifold and 100% factory tested. They are available in a single station manifold up to 12 station assembly standard.
