The 2588 is a pneumatic control, equipped with a long handle that allows for gradual pressure increases with a sensitive response. The 2588 is manufactured from bronze and stainless steel, ensuring longevity in harsh environmental conditions.
The 2588 can be graduated in as little as 1 PSI increments, but does require a 3329 pressure compensated relay valve to regulate flow into a brake or other application. The 2588 is available in various pressure ratings, but is typically recommended for up to a 120 PSI (8.27 BAR) maximum.
