Product Description

Technical Parameters

Valve Type:	Flange ball valve	Structure:	2PCS type
Standard:	BS5351	Workmanship:	Investment casting
Sealing direction:	Single-directional	Sealing grade:	Zero leakage
Temperature:	-20°C < T < 120°C	Operation:	Handle

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.

Key Advantages

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.

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.

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 & Application

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.

Frequently Asked Questions

What is the advantage of the floating ball design in pneumatic valves?

The floating ball design allows the ball to move slightly under medium pressure, pressing against the downstream seat to ensure a tight, zero-leakage seal, especially in low to medium pressure systems.

How does the fault safety protection work?

The valve uses a single-acting actuator with a spring reset function. If the air supply is interrupted, the internal spring automatically forces the valve back to its default safe position (open or closed).

Are these valves suitable for corrosive media?

Yes, with body materials available in CF8 (304) and CF8M (316) stainless steel, and PTFE seals, these valves are highly resistant to nitric acid, acetic acid, and other strong oxidizing media.

What temperature range can this valve handle?

This specific configuration is designed for temperatures between -20°C and 120°C, making it suitable for a wide range of industrial fluid applications.

Can the valve be used for flow regulation?

While primarily used for on/off service, when equipped with a valve positioner, it can achieve proportional adjustment to regulate flow within the pipeline.

What standards do these valves comply with?

These flange ball valves are designed and manufactured according to the BS5351 standard, ensuring international compatibility and quality assurance.
