Characteristics
Pneumatic ball valves are driven by compressed air to achieve valve opening and closing control. The ball of the floating pneumatic ball valve is floating and sealed by the medium pressure pressing against the sealing surface at the outlet end, suitable for medium and low pressure applications.
Advantages
1
Fault Safety Protection
The spring reset function of the single acting actuator and the stable air supply guarantee of the triple component ensure that the valve automatically resets when the gas is cut off, which is suitable for scenarios with strict safety requirements such as chemical, gas, and oil industries.
2
Accurate and Stable Control
The pressure reducing valve of the triple component can accurately adjust the air source pressure, avoiding pressure fluctuations that may cause incomplete valve opening and closing or action jamming; Filters and oil mist devices extend the service life of actuators and valves, reducing maintenance costs.
3
Easy and Efficient Installation
The three components can be integrated with the actuator and solenoid valve for easy pipeline connection, without the need for additional gas source treatment equipment, shortening the on-site installation and commissioning cycle.
Packing
Standard export wooden case packaging
Application Scenarios
The pneumatic ball valves are widely used in industries such as petroleum, chemical, natural gas, pharmaceuticals, and electricity. It is suitable for pipeline systems containing various media such as water, steam, oil, nitric acid, acetic acid, viscous fluids, and strong oxidizing media. It is used to switch and cut off pipeline media, and can also achieve proportional adjustment when equipped with valve positioners.
Frequently Asked Questions
Q
What is the operating temperature range of this pneumatic ball valve?
This pneumatic ball valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for a wide variety of industrial applications including chemical, oil, and gas environments.
Q
What standard does this flange ball valve comply with?
This flange ball valve is manufactured in compliance with the BS5351 standard, ensuring consistent quality and dimensional accuracy for international industrial pipeline systems.
Q
What happens to the valve if the air supply is cut off?
The single-acting actuator features a spring reset function. If the air supply is interrupted, the valve will automatically return to its default (fail-safe) position, ensuring safety in critical applications such as chemical, gas, and oil pipelines.
Q
What media is this pneumatic ball valve compatible with?
This valve is compatible with a wide range of media including water, steam, oil, nitric acid, acetic acid, viscous fluids, and strong oxidizing media, making it highly versatile for petroleum, chemical, pharmaceutical, natural gas, and power industries.
Q
Can this valve be used for flow regulation in addition to on/off control?
Yes. While the valve is primarily designed for switching and media cut-off, it can also achieve proportional flow adjustment when equipped with a compatible valve positioner.
Q
How is the valve packaged for export?
The valve is packaged in standard export wooden cases, designed to protect the product during international shipping and handling, ensuring it arrives at its destination in perfect condition.
