400H 多（duō）個係列平行（háng）線閘閥（fá）使用非金屬進行聯係式特殊整體結構，手腳值得信賴，具備極高的隔離使用性能，普遍應用於恒溫（wēn）、 超高壓到（dào）極超低溫具體條件下（xià）的困難隔離閥、拋空閥或進行進（jìn）行大 標（biāo）準調整閥采用，具備連（lián）年實績。

另外，非金屬進行聯係（xì）式整（zhěng）體（tǐ）結構自己具備防水具體功能（néng）。

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.
