Performance Advantages:
1. Compact Design and Low Flow Resistance
The pneumatic globe valve features a highly compact structure, minimizing spatial footprint. In industrial facilities where space is at a premium, this design effectively conserves valuable floor area and facilitates optimal equipment layout. Additionally, the valve exhibits low flow resistance, enabling smooth medium transmission through pipelines, reducing energy consumption, and enhancing overall process efficiency. Analogous to unobstructed lanes on a highway, this ensures efficient and uninterrupted flow, thereby improving system performance.
2. Opening and closing characteristics: During the opening and closing process, the pneumatic stop valve is noise-free, has no dead corners, and has zero leakage. This makes it perform well in scenarios with strict requirements for the environment and medium. In the food and beverage industry, the production process requires strict control over hygiene conditions. Any leakage may lead to product contamination and affect food safety. The zero-leakage feature of pneumatic stop valves ensures a clean production environment and guarantees product quality. In the pharmaceutical industry, its feature of having no blind spots avoids drug residues and ensures the purity and efficacy of the drugs.
3. Installation and usage flexibility: It can be installed by turning around, enabling the use of the same actuator for both normally open and normally closed applications. This design offers great convenience to users. In practical applications, users do not need to prepare multiple actuators for different working modes, reducing equipment procurement costs and maintenance workloads.
4. Replaceable valve disc design: Both the conventional valve disc and the regulating valve disc can be freely replaced to meet different usage requirements. When the production process changes and precise regulation of the medium flow is required, users only need to replace the regulating valve disc to easily achieve the function conversion, without having to replace the entire valve. This not only saves time and cost but also improves the utilization rate of the equipment.
The pneumatic globe valve is available with multiple connection types—clamp, weld, thread, and flange—ensuring compatibility across diverse industrial applications. In high-hygiene sectors such as food and pharmaceuticals, clamp connections offer quick installation and disassembly, facilitating thorough cleaning and maintenance while minimizing the risk of media residue. Weld connections are ideal for high-pressure, high-temperature systems requiring maximum sealing integrity. Thread connections are typically employed in small-diameter, low-pressure pipelines due to their ease of installation and cost-effectiveness. Flange connections, known for their mechanical strength and pressure resistance, are widely used in large-scale industrial equipment and high-pressure pipeline systems.
