Pneumatic AVAMO AL

The Actuator

Our AVAMO AL actuator series features typical linear actuators which will be produced according to customer requirements. NTF will not have a typical standard due to the fact that all globe or gate valve manufacturers have their own philosophy and stroke length of the valve.

The actuator is designed for great longevity, ensured by nickel or Ionit Ox plated cylinders. Chromium plated rods and custom paint jobs provide an excellent protection against corrosion.

The AL series can be used for on/off or modulating applications. It is available in double- or single acting versions and delivers forces up to 5.500.000 N


AVAMO AL actuators have a modular design and can be equipped with several options. The linear actuator can be driven by air, gas or oil and is ether available as single- or double-acting version. NFT also applies a spring cylinder for emergency-shut-down-applications if necessary. The cylinder can be fitted on ether sides of the actuator to create a fail-close or fail-open configuration.
