Chemical & Petrochemical
A rugged industry demanding absolute reliability. Lethal media. Viscous sludge. Corrosive applications. Toxic emissions.
Cornerstone Valve has solutions for your most extreme chemical & petrochemical
Emission control hazards are the top concern in this industry. The lethal media calls for live-loaded redundant sealing mechanisms with test ports for zero emission confirmation.
Down-time means viscous sludge turns into a nightmare cleanup - and costly repairs. Solids proofing, specific sealing mechanisms and judicious material selection equate to our valve’s long service life.
Cornerstone engineers team up with their customers to help design valves specific to each industry need.
Careful selection of materials specific to media and process conditions accompanied by knowledgeable engineering choices mean valves that work - day in and day out.
A polypropylene reactor let-down service struggled to keep its crucial-service valves working. After spending $5,000 a week attempting to maintain operating standards, it called Cornerstone.
Cornerstone’s solids-proof design was selected as a style replacement. Special scraper seat faces clean the ball every 5 minutes it cycles – preventing product from jamming the valve components and building on the ball.
The result: elimination of a weekly maintenance cost of $5000 for 22 installed valves. Cornerstone model SB-2 valves have been in continuous service for the client for more than 8 years.
