4 Considerations When Buying Pneumatic Actuator Ball Valve
01
Pipe Diameter
The valve size should match the pipe diameter for proper integration. For example, if you have a pipe with a diameter of 2 inches, you should use a 2-inch valve to achieve a proper fit and function. A mismatched size can lead to improper flow and potential system issues. Always measure the pipe diameter accurately before selecting a valve.
02
Actuator Type
Pneumatic actuators come in different types, such as spring-return and double-acting. Spring-return actuators return the valve to a default position when air supply fails. Double-acting actuators require air pressure for both opening and closing. But wait, let me tell you something: select the actuator type based on the application requirements for reliable operation.
03
Faixa de temperatura
Consider the operating temperature range of the valve. Verify that the valve can withstand the minimum and maximum temperatures of the application. Operating outside the temperature range can damage the valve and affect performance. Proper temperature consideration provides long-term reliability.
04
Easy-to-Maintain Valves
Evaluate the maintenance requirements of the valve. Some valves need frequent servicing, while others require minimal maintenance. Choosing a valve with lower maintenance needs reduces downtime and operational costs. NTVAL designs valves with durability and ease of maintenance in mind, providing cost-effective solutions.
