Enquire Now →Pneumatic cylinders are used for quarter turn valve automation where controlled, repeatable and reliable valve movement is necessary. The operating pressure available is converted into mechanical force to open, close or position the valve as required by the system.
Forex Valves provides pneumatic cylinder valve actuation solutions for applications involving butterfly valves, ball valves and other quarter turn valve arrangements. The actuator configuration can be chosen based on valve torque, bore size, operating pressure, service medium, operation frequency and installation conditions.
The range is meant for industrial use where reliable valve operation and controlled movement is important. Depending on the application, the cylinders can be equipped with suitable control and monitoring accessories for automated or modulating operation.
The range of pneumatic cylinders is available in a number of configurations to suit a wide variety of valve operating requirements. Bore sizes up to 24 inches and valve torque capabilities up to 180,000 ft-lbs are available.
Depending on the configuration selected and the application requirements, these actuators can be used with air, oil or water supply media up to 150 psig. Corrosion resistance and material compatibility are important considerations for services with non-metallic and stainless steel construction options.
This design is particularly well suited for quarter-turn valve applications such as butterfly and ball valves. Cylinder actuators can be used in control systems requiring remote operation, position monitoring or modulating control.
Valve actuator should do more than just move. It should be able to provide adequate torque over the whole valve operating cycle and be reliable under the actual pressure, temperature and environment conditions of the installation.
Thus, pneumatic cylinder actuators are selected based on the valve operating torque, the required safety margin, the supply pressure, the cycle frequency and intended service. Proper sizing helps the valve to achieve the required position without over burdening the valve stem or actuator components.
For exposed installations, moisture, chemicals and corrosive environments also make important the construction and material selection. Stainless steel or non-metallic options can be added to provide additional corrosion resistance.
The actuator can be combined with appropriate control components such as limit switches, solenoid valves and positioners for automatic installations. This allows the valve to be operated and monitored within a larger control system.
Positioners are used where modulating operation of the valve is required and manual override facilities provide a practical means of operating the valve when the normal supply medium is absent.
These configurations can be made part of plant automation and SCADA based control systems, depending on the project requirements.
The actuator range can be tailored to the valve and application requirements. Products can be manufactured to meet the requirements of AWWA C541 for hydraulic actuators and used with valve applications covered by AWWA C504 and AWWA C507, depending on the selected configuration.
Thanks to the manufacturing under an ISO 9001 certified quality system, controlled production and consistent quality are maintained from start to finish.
The right actuator should be chosen according to the type of valve, valve size, operating torque, supply pressure, operating medium, cycle frequency and environmental conditions.
Forex Valves can help customers, engineering companies, EPC contractors and project suppliers to determine the correct pneumatic cylinder for valve actuation according to the specific valve and operating requirements.
Please provide your valve type, size, torque requirement, operating pressure and service condition to our team for actuator sizing or project requirements and technical inquiries.
