Nominal Diameter: DN***-DN***0

RZ*4F*2.5,2.5Q,2.5C Manual Multi-sealed gas cut off valve

Application:

This series of valves have good self-sealing performance, the valve is installed on the external injection system, When the valve is closed, through the injection system to the valve chamber filled with water or charged with nitrogen, thereby blocking medium, to achieve the isolation of the system and the atmosphere, to ensure good tightness of the system.

Features:

1,Rubber seal and water, gas double seal system,can completely isolated to the atmosphereto, ensure the system has a good airtight;

2,The double plate bi-directional elastic sealing, flexible opening and closing, rapid, reliable sealing;

3,Simple and compact structure, easy maintenance;

4,Inner connected parts are made of stainless steel, durable, long life;

5,The high-performance filler with minimal frictional resistance, self-lubricating, anti-gas and a variety of corrosive gases, the operating system is flexible, reliable sealing;

6,The valve has a drain valve, in the drainage process, not only for cleaning valve cavity,but also facilitate to eliminate the impurities accumulated in the valve body together with the water;

7,Flange connection, operation method:manual, handwheel,electric.
