Description

Product Introduction

To automatically start and stop flow faster than motor-driven valves, these operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve Valves don’t require a minimum pressure drop between the inlet and outlet for operation.

The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.

Butterfly valves can wafer style, lug style, flange style. Their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.

Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.
