Micro pneumatics manufactures butterfly valves. These include shaft, disc and bodies. Their high performance results from the incorporation of an offset [eccentric] disc in conjunction with bi-directional pressure assisted seats. This combination offers improved throttling and shut off capabilities. Micro pneumatics is a single source for purchase of valves, actuators and accessories completely mounted and ready. The company commenced operations manufacturing pneumatic rotary actuators and later ball valves. Later it added butterfly valves and dampers, and now, high performance butterfly ball valves. These are available with pneumatic double acting or spring return actuators and a variety of accessories including limit switches, solenoids and positioners. Valve flow data: micro high performance wafer butterfly valves provide long-lasting tight shut off and a long service life. Valve torque data: this torque chart is to be used as a guide for actuator selection. An actuator should be selected that provides the same or greater torque output.
