铸钢双向蝶阀

描述

The Cast Steel Bidirectional Butterfly Valve is a flanged, offset-disc butterfly valve designed to seal equally well against pressure from either side. It can be installed without regard to flow direction and used where flow reverses, making it a versatile isolation valve for industrial water, oil and gas lines.

技术规格：

• 压力等级： PN16 / PN25 / PN40
• 尺寸范围： DN50 – DN1200
• 适用介质： Water, steam, oil, gas, air
• 工作温度： -29°C至200°C（软密封）/最高425°C（金属密封）

Main Parts and Materials:

产品主要特点：

1. Two-Way Sealing: Zero leakage with pressure from either side.
2. Free Installation Direction: No flow arrow restriction.
3. Cast Steel Body: Strong and suitable for higher pressures and temperatures.
4. 操作扭矩小： Eccentric disc reduces seat friction.
5. 驱动选项： Worm gear, electric or pneumatic.

应用：

适用于 石化装置, 电厂, 水处理以及 工业工艺管线. Specifically suited for pipelines where flow direction can change.
