400H 平行闸阀

400H 系列平行闸阀采用金属接触式结构，动作可靠，具有的切断性能，广泛应用于高温、 高压到极低温条件下的紧急切断阀、放空阀或作为大 口径调节阀使用，具有多年实绩。

此外，金属接触式结构本身具有防火功能。

The Parallel Slide 400H valve provides maximum shutoff  performance through its metal-to-metal, wedge type sealing mechanism. Its excellency as an emergency shutdown/relief valve, or a control valve of a large diameter, has been proven in a variety of on-off applications, as it seals off all pressures from low to high. Fluids of extremely low temperature can be controlled, too.

Its all metal construction automatically assures fire-safe function as well.
