Flanged valve top works design is completely separate from the valve packing gland preventing absorption of force from the quarter turn stop impact and misapplied maintenance and greatly reduced stem packing adjustments.
The valve top flange is designed to facilitate ease of automation by including ISO 5211 bolting patterns.
The valve top flange can be adapted with a secondary containment bonnet for critical requirements, fugitive emissions, or cryogenic applications.
The floating ball design offers a positive leakproof seal and is pressure-activated providing leak proof performance.
Flow capacity of the full port series is the same as a similar-sized piece of pipe, as a result, it suffers no appreciable pressure drop or head loss across the valve as may be the case with other valve types – a constriction-free flow path.
Graphite stem packing meets the highest fire standards under extreme conditions.
Optional design features include a Cryogenic Extension, Control Valve, and Fusiblke Link.
