Features & Benefits
Easy selection, broad product portfolio
DSV...DGH and DSV...DGF valves can be supplied in 0,1 bar increments. Special versions in other materials such as stainless steel, or with a thermal resistance of up to 400°C, are available upon request.
According to standards
All valves are TÜV type approved and comply with the standards listed under Approvals.
High blow off rates
Enhanced lift and capacity thanks to a special valve construction.
Cleaning of seat possible
A fully detachable bonnet allows for easy cleaning of the gasket while leaving valve settings unchanged.
