Integrated Valve & Actuator (IVAC)

IVAC = Integrated Valve & Actuator family — Norgren's solution to the wiring nightmare of distributed pneumatic machinery. On the integrated-valve versions (PRA/862000, PRA/882000) the 5/2 or 5/3 valve sits directly on the cylinder body with a single electrical connector for control and a single port for compressed-air supply. Four ISO 15552-based variants: PRA/822000 Smoothline and PRA/842000 Cleanline — base cylinders supplied without the integrated valve (PRA/842000 in NSF H1 / EN 1672-2 food-grade build); PRA/862000 Industrial — complete functional unit with integrated valve, flow regulator, IP65; PRA/882000 Clean Line — complete functional unit with integrated valve, LED display, food-grade IP67. ATEX zone 1/2 variants (PRA/822000/EX, PRA/842000/EX) available.

Eliminates pneumatic distributionConventional approach: central valve manifold → tubing → cylinder. Long tubes = air-volume delay = slow actuation, plus failure points (leaks at every fitting). IVAC integrates the valve directly on the cylinder, so the only pneumatic plumbing left is the single supply line to the unit.

Single electrical + single pneumatic connectionA single electrical connection for valve + position feedback (M12 8-pin on PRA/882000; DIN EN 175301-803 form C on PRA/862000) (reed/solid-state switches mounted flush). One air supply port plus a single exhaust. Wiring time at install drops from minutes per cylinder to seconds. Ideal for machine-mounted multi-cylinder installations and modular automation.

Energy efficientShorter pneumatic path = less air volume to fill on each stroke = less compressed-air consumption. Norgren's data shows up to 50% lower per-stroke air use vs. a remote-valve installation, depending on tube length saved. The PRA/862000 has integrated flow regulators for further optimisation.

Frequently asked questions

IVAC is roughly 30-50% more expensive per cylinder than the same bore in a regular ISO 15552 + remote 5/2 valve setup. It pays back when: (1) the install time saved is significant (multi-cylinder machines, modular layouts), (2) the wiring path saved matters (long tube runs were causing actuation delay), or (3) the fewer leak points matter (food/clean industry, where every fitting is a contamination risk). For single-cylinder retrofits in existing manifold layouts: stick with regular + remote valve.

Yes — IVAC follows ISO 15552 mounting, so the cylinder fits the same brackets. The wiring side changes: instead of running cable to the central manifold's solenoid bank, you run direct to each IVAC's electrical connector. Often easier because cable runs are shorter and straight. The pneumatic side simplifies — disconnect the manifold tubing to the cylinder, replace with a single supply line direct to the IVAC's air-in port.

Smoothline (PRA/822000): general-industry base cylinder — order the valve separately. Cleanline (PRA/842000): food-industry base cylinder — smooth, spherical body per EN 1672-2, NSF H1 lubricant, IP67 (order the valve separately). Industrial (PRA/862000): complete IVAC unit with integrated 5/2 or 5/3 valve and flow regulator, IP65, for general industry. Clean Line LED (PRA/882000): complete IVAC unit with integrated valve, LED display, M12 8-pin connector, food-grade IP67. Pick by environment + integrated-valve requirement.
