Piston globe valve
The Piston Globe Valve is engineered for pipelines requiring accurate flow regulation and high-pressure sealing. Its piston-guided disc reduces friction, enhances stability, and ensures reliable shut-off under severe conditions. Suitable for steam, oil, gas, and chemical media, the valve delivers long service life, minimal maintenance, and high operational safety.
Piston globe valve
The Piston Globe Valve utilizes a guided piston disc design to provide superior control and sealing performance in high-pressure, high-temperature industrial systems. The piston mechanism ensures smooth linear movement, reducing wear and extending operational life compared with conventional globe valves.
Manufactured from carbon steel, stainless steel, or alloy materials, it meets stringent industrial standards and is suitable for steam pipelines, high-pressure oil systems, and chemical processing units. Available in manual, electric, or pneumatic operation, the valve can integrate seamlessly into automated process systems.
Our Piston Globe Valves are manufactured and tested to meet international standards:
