Pneumatic ball valves are operated by compressed air and regulate the flow of compressed air. This allows for fast and reliable control of fluid flow in industrial applications. PU, PV, making it a multifunctional option for pipelines and piping systems. [Easy to install and disconnect] The Push Connect Valve has a joint connection at both ends, making it fast and easy to connect and disconnect without the need for tools or skills. Simply push the pipeline or pipe into the valve body until it clicks into place, and the locking mechanism ensures connection. Therefore, they are cost-effective for connecting pipelines or pipelines in industrial applications. Durability: The push valve is made of High-quality materials. These valves offer the advantages of two materials, providing corrosion resistance, structure, strength, pressure resistance, and long-term use. The air control valve has been designed to create a reliable leak proof seal. The design of the valve combines a stainless steel clamp ring and an O-ring seal, ensuring a safe and watertight connection. Therefore, air control valves are known for their reliability and leak free connections Multi functional: Union ball valves are typically used in pneumatic systems to connect pneumatic lines to actuators, cylinders, and other components; Widely used in compressed air systems to establish safe connections between air compressors, air tools, and pneumatic equipment; It can also be used in hydraulic systems to connect fluid lines to pumps, motors, and other hydraulic components. size: 4mm Material: Metal colour: Black Package Contents: 3 x Connect Valve Only the above package content, other products are not included.
