Severe Service Control Valves

Severe Service Control Valves

Longer service life and lower maintenance costs are made possible through precision engineered valve and trim options — even in corrosive, erosive and high-velocity applications.


A range of advanced anti-erosion, noise reduction and anti-cavitation selections neutralizes the detrimental wear and tear that too often reduce valve life or lead to failures. Maximum flexibility is achieved through severe service products that incorporate a range of material, pressure and temperature options.
