双隔离截止阀组

双隔离截止阀组（Double Isolation Valve Assembly）是一种高度安全性的阀门组合装置，由两个独立的截止阀和一个中间排放阀组成，形成双重隔离屏障。该产品专为需要安全隔离的工况设计，确保在维护、检修或紧急情况下实现完全稳定的介质切断。

双隔离截止阀组主要特点

双重隔离保护：两个独立操作的截止阀提供冗余密封，确保零泄漏

中间排放功能：可安全排放两阀之间腔体内的介质和压力

高稳定性设计：符合API 6D、ISO 15848等标准

多种材质选择：碳钢、不锈钢、合金钢等，适应不同介质要求

多种连接方式：法兰、对焊、承插焊或螺纹连接

操作方式灵活：可选手轮、齿轮箱、气动或电动执行机构

Double Isolation Valve Assembly Product Overview

The Double Isolation Valve Assembly is a highly secure valve combination consisting of two independent globe valves an intermediate bleed valve, forming a dual isolation barrier. This product is specifically designed for applications requiring the highest level of safety isolation, ensuring completely reliable medium shut-off during maintenance, inspection emergency situations.

Key Features

Dual isolation protection: Two independently operated globe valves provide redundant sealing for zero leakage

Intermediate bleed function: Safely discharges medium pressure between the two valves

High-reliability design: Complies with international standards including API 6D ISO 15848

Multiple material options: Carbon steel, stainless steel, alloy steel, etc. to suit different medium requirements

Various connection types: Flange, butt weld, socket weld threaded connections

Flexible operation: Optional handwheel, gearbox, pneumatic electric actuator
