Quarter Turn Pneumatic / Electric Valve Actuation
Pneumatic and electric actuators can be easily fitted on our ball, multi-port, and butterfly valves. Some features and functions include normally closed, normally open, or double-acting operation; corrosion-resistant aluminum bodies, pre-loaded springs, and adjustable cams. Many accessories such as visual position indicators, limit switches, 3 and 4-way solenoids, and positioners are also available. There are three basic control functions through quarter-turn automation: Double Acting which requires power to open and close the valve, Normally closed referred to as “fail safe closed”, the default position is closed and it requires power to open the valve and lastly the Normally open known as the “ fail-safe open”, the default position is open and the actuator requires power to close the valve.
Product Types & Specifications
Automation is an ideal solution for precise control of many valves in a system, when valves are remotely located, or when the process requires constant monitoring and adjustment. Pneumatic and electric actuators can be easily fitted on our ball, multi-port, and butterfly valves.

pRODUCT OVERVIEW
The three basic control functions available through quarter-turn automation are:
- Double Acting – This requires external power for each stroke. For example, power to open the valve, then power to close the valve.
- Normally Closed – Also referred to as “fail safe closed”, the default position is closed and the actuator requires power to open the valve.
- Normally Open – Also referred to as “fail safe open”, the default position is open and the actuator requires power to close the valve.
Quarter turn automation can be found in applications such as:
- Aquarium Piping Systems
- Metals & Mining
- Shipbuilding and Offshore applications
- Water and wastewater treatment
- Chlor-Alkali Processing
