FAQs
In what kind of applications is a pneumatic butterfly valves suitable for?
The pneumatic actuator butterfly valve serves multiple applications because it provides both versatility and economical operation for industrial processes and nuclear and aerospace system operations.
These valves operate in industrial environments including power plants and petrochemical plants and paper mills and steel mills to control flow rates of steam and gas pipelines. The valves operate in low-flow diverting services which connect two or more lines that maintain equal pressure. The valves function best as isolation valves for higher pressure systems.
Pneumatic actuator butterfly valves quality assurance
The quality control and assurance procedures for pneumatic actuated butterfly valves remain strict. The testing of each valve for performance and safety occurs before the product reaches the customer. The validation process includes design verification and mechanical operation testing as well as flow rate characteristics evaluation and pressure drop assessment and air leakage and noise level verification to meet the highest international quality standards. The pneumatic actuator includes end-of-travel limit switches which prevent overtravel and related issues to ensure safe operation in any application.
What is a pneumatic butterfly valves?
A pneumatic actuator butterfly valve functions as a quarter-turn rotary flow control valve which controls the flow of air and liquids and other materials through shut-off and regulation operations. The valve consists of two main parts which include the disc-shaped body containing the actuator and internal components and the butterfly disk that rotates inside the body. The butterfly disk contains a central opening which functions to determine the fluid flow rate.
