Allgemeine Informationen<br />
Description<br />
1. General characteristics<br />
<strong>Rotary</strong> <strong>gate</strong> <strong>valve</strong> <strong>DSR</strong><br />
The <strong>RMA</strong> rotary <strong>gate</strong> <strong>valve</strong> type “<strong>DSR</strong>“ is an extremely robust welded steel, dust resistant shut-off <strong>valve</strong> for<br />
installation in gas pipelines (coking plants, fission- and natural gas).<br />
2. Construction / Function<br />
The main features of this metal-sealing, single-plate-parallel <strong>valve</strong> are the precision machined-lipped<br />
surfaces of <strong>gate</strong> and sealing plates, which are floating-mounted, by preapplication with spring-washers.<br />
This system ensures a movement of close-plate over entire swivelling range without gaps.<br />
The totally gapless metal seal prevents penetration of dirt during opening and closing of close-plate.<br />
At the same time a consistant and undamaged sealing surface is preserved which guarantees lasting<br />
operation life.<br />
In the open position, a full passage is ensured. The flow direction is from weld end to vent plug.<br />
To ensure permanent lubrication of moving parts, interior housing is filled with a special oil.<br />
The drain plug on top of housing serves for oil-filling and level checking.<br />
3. Corrosion prevention<br />
The outer shell has as standard a PUR (polyurethane) coating.<br />
