    other applications on request

N/A ARI-Control valves are suitable for the use with pneumatic or electric actuators. According to the application two different variations are possible (see drawings on the left)
Size 1/2"-11/4" with mixing plug can also be used for diverting service (1 inlet, 2 outlets). In exceptions the design with mixing plug can also be used in diverting service for Size > 1 1/2". Only small closing pressures are possible.
Design with diverting plug will be used exclusively for diverting service.
