Spirax Sarco check valves help prevent reverse flow, reduce waterhammer risk and protect equipment in steam, condensate, water and process systems.
Non-return protection works best when the surrounding line condition is also controlled. Add strainers when debris could damage seats or internals, and use steam separators where entrained moisture is part of the reliability problem.
If the installation also needs manual shut-off around the protected line, continue into isolation valves. Where shutdown vacuum is the bigger protection risk, compare vacuum breakers.
