Dampers for gas control applications
March 2013
Valves, Actuators & Pump Control
PSV Mitech‘s locally designed and manufactured dampers are ideally configured for gas control applications where a tight shutoff is not required. They can be made suitable for high pressures and temperatures and are much more cost-effective in these applications than disk valves. Dampers are effectively similar to butterfly valves except that they are not fitted with damper to body seals.
They are subject to a leak rate not exceeding 1% of their rated flow and are available in sizes from 200 to 2500 mm, with flange ratings of #600. If required, larger sizes are available on request.
The dampers can be manufactured in flanged, wafer or lugged pattern designs in single-door, double-door or oblong vane-type configurations. Robust in design, they have carbon or stainless steel bodies and disks and the shaft seals can be either PTFE or graphite, depending on the operating temperatures. Typical applications are those found in mining, petrochemical, food, breweries, pulp and paper, and power generation.
