Bubble-tight-Soft-Seated-Valve

Nhan Viet ICS JSC offers bubble-tight soft seated valves

Besides to the well-known hard seated valves Soft Seated Valves are considered to be bubble-tight and leak-free. Bubble-tight shut off is required to accomplish accurate measurement through the practice of instrumentation valves and manifolds.

The Challenge

Accomplishing this leak free shut off on valves used in industrial applications is sometimes a challenge. The challenge is due to the service or media in contact with the valve/manifold. Media can be gas, vapor, liquid, steam or a combination of all. The requirement of a soft seat is to offer ideal bubble-tight shut off and repeatable bubble-tight performance.

In the case of natural gas where the media is corrosive and wreckage is common eventually causing the best of valves to begin leaking the ability to replace the seat(s) is necessary. By changing the seats a bubble-tight leak free installation is again succeeded. The need to buying a new valve or manifold is not necessary saving users operating and maintenance costs.

The Solution

The 3/8″ (9.5 mm) Bore Size offers a larger internal flow path which helps to reduce freezing and plugging issues. The “Joule-Thomson” effect* is also reduced in many gas applications.
