Pulstronic is a new pneumatic proportional valve from Asco Joucomatic, designed for applications requiring variable pressure regulation. Developed from Asco Joucomatic's novel Sentronic proportional valve, Pulstronic offers a cost effective solution where the levels of response required by a particular application are not extreme. Pulstronic is a self-contained, electropneumatic proportional valve with an integrated control loop that provides precise regulation of pressure.
Designed for operation on normal filtered air (50 micron), Pulstronic employs ASCO Joucomatic's innovative poppet technology proven on the market leading Sentronic proportional valve - to provide good rates of response with minimum hysteresis - less than 1% of maximum output pressure (PMR), when increasing or decreasing pressure.
In addition, repeatability is excellent at 0.5% of PMR (10bar).
The IP65-rated Pulstronic is available in four versions: the DN4 with G 1/8 ports, the DN7 with G1/4, the DN12 with G 1/2 and the DN 0.5 with instant fittings to accept 4mm flexible hose.
The latter version is particularly adapted for piloting pneumatically operated valves or boosters.
All the valves operate with analogue set points of 0-10V, 0-20mA or 4 20mA, and offer operational security in the form of a "pressure held at power failure function".
Typical applications for the Pulstronic include: compensation of thickness on pinch rollers; spot welding equipment; turbo-supercharging; and materials testing.
