Electric water-cooled butterfly valve _ Pneumatic water-cooled butterfly valve

1、 Product Definition and Core Features
Electric water-cooled butterfly valve
Made of 310S stainless steel or Q235 material, driven by electric actuators, supporting MODBUS RTU protocol and DCS system integration.
Built in circulating water cooling system, temperature resistance range -20 ℃ to 1300 ℃, leakage rate ≤ 1-2%.
Pneumatic water-cooled butterfly valve
Pneumatic actuator drive (double acting/single acting), optional accessories such as solenoid valves and limit switches.
Suitable for high-temperature flue gas pipelines such as RTO incineration systems, with a temperature resistance of up to 1500 ℃ (short-term).
