Description

Series 79 on Type-57P Butterfly Valve

The Type-57P butterfly valve from Asahi/America has the ability to mount a series 79 pneumatic actuator to allow for the valve to be controlled via an air supply. Actuators are sized to operate on 80 psi of air pressure, and can be sized to operate on different air pressures upon request. Actuators are available as either air-to-air (double acting) or air-to-spring (single acting), with air to spring units having the option to fail either open or closed. The actuators are mounted on the valve through a coupling and bracket set up with an ISO bolt pattern. Units have a visual position indicator and operate as quarter turn actuators. Automation can be performed through optional equipment such as solenoids, positioners or BUS systems.

Ideal Applications Include:

Chemical Processing, Bleach Plants, Aquariums, Mining, Water Treatment, Landfills, Swimming Pools, Power Plants
