Models 3740 and 3740H

Isolair, Inc. boom valves are designed for superior ease of operation and maintenance. Both the 3740 and 3740H valves are 1 1/2 inches full port with positive shut off valves. The ball valve provides recirculation and positive suck back on spray booms.

Replacement of seals and the chromium plated ball can be accomplished while in the field. Model 3740 is operated by a 12 V or 24 VDC electric motor. Model 3740H is hydraulically actuated by the aircraft's hydraulic system.

The valves are made in the USA and manufactured to Isolair's rigid aircraft quality specifications. These units are designed as direct replacements in Isolair spray systems but may be adapted to other brand spray systems to improve current performance.
