Fluid Power


Engineered for the high flow of non-corrosive fluids, light industrial liquids, slurries, or gasses, SV12 series solenoid valves are direct-acting, two-way, normally closed units. Pressure differential is less than 10 inches water head pressure in the direction of flow for drip-tight sealing. Valves are available in 1/8- and 3/1 6 -inch orifice sizes with operating pressures up to 175 psig.

Stainless steel, 3/4- and 1-inch, two-way poppet valves provide bubble-tight closure, even under low pressure. Designed for applications that require quick positive control from a low pilot signal, the valves are rated 500 psi, air-oil-water. Viton seals and brass/nickel-plated pilot caps allow quick access to internal parts.

Proportional valve

Designed for precision applications requiring flow rates up to 800 gpm, Double Solenoid Proportional Valves feature integrated electronics to monitor spool position. Spool options include 2:1 differential spools and regen spools. Two cables connect the electronics to the pilot valve, which lets users incorporate the unit into safety circuits in combination with the company's Interrupt Safety Adapter.

Valve controller

The Valve Bus Box (VBB) enables control of stand alone, in-line pneumatic valves and vacuum generators via the DeviceNet protocol. Users mount the VBB electronics module to one side of a pneumatic component, and make all electrical connections with IP-65-compatible plugs and connectors. Supply voltage is 24V dc; operating range is -5 to 50C.

Air compressor

An enclosed "V" crankcase with perpendicular piston cylinders lets VORTEX series oil-less air compressors operate at 86.5% efficiency at open flow and 53.4% at 100 psig. Aluminum construction provides long service life and light weight. Available from 1/4 to 2 hp, the units provide open flow rates to 12.75 cfm, continuous pressure up to 125 psig, and restart pressure up to 125 psig.

Designed for corrosive or high-purity fluids, the Inert Proportional Valve provides infinitely variable flow control. Flow is proportional to current input into the 24V dc valve driver. A diaphragm constructed of either ethylene propylene or Viton GF isolates the fluid path from the solenoid, and the poppet and seat provide a bubble-tight seal.

The E4 1.5-inch stainless-steel bolted pump features an Elima-Matic(R)air valve for non-stalling, anti-icing, and lubrication-free service. Beaded-style diaphragms eliminate bolt-hole alignment, and tapped air chambers eliminate chamber fastener nuts. The bolted design provides good sealing for liquids with low specific gravity and low viscosity.

Flow controller

Designed for harsh indoor and outdoor applications, the IP65-compliant Quantim(TM)precision mass flow controller is water-tight and can be hosed down. Its direct measurement method requires no conversion factor for different fluids or process conditions, and provides 0.5% accuracy for low-flow (less than 3,000 grams/hour) processes.
