BVT-PB linear pneumatic actuator
BVT’s linear pneumatic actuators are designed for use in power and oil & gas industries, or in any application where steam / water valves are involved.
The actuator is installed on top of a control valve or an isolation valve with a coupling connecting the actuator piston to the valve stem. It is included as standard on BVT valves where pneumatic actuation is required, and is also sold as an upgrade for existing valves. BVT designs and builds the actuator to match the force requirements of the valve and the stroke time and functional / environmental requirements from the customer.
Key features
