Обратные клапаны Swagelok®
Проходные обратные клапаны Swagelok предлагаются в широком диапазоне регулируемых и фиксированных значений давления открытия для контроля обратного потока в системах общего назначения и высокой степени чистоты. Клапаны, регулирующие избыточный расход, предотвращают избыточный расход за клапаном, повышая целостность и безопасность системы.
View Check ValvesSwagelok® check valves are designed to allow fluids to flow in one direction only. Our check valves are available in a variety of designs, including poppet, lift, and all-welded versions for use in general-service or high-purity applications, including those featuring medium or high pressures.
Swagelok check valves are available with a variety of end connections and sealing materials, allowing users to find easy-to-integrate solutions compatible with their systems and process media. Certain Swagelok check valves feature all-welded designs to provide reliable containment of system fluid in high-purity applications, and some are composed of ultrahigh-purity fluoropolymer and feature no O-rings, maximizing flow while reducing pressure drop, eliminating no-flow areas, and providing excellent leak integrity.
Swagelok® XS series excess flow valves have a slotted poppet which moves to the tripped position when excess flow occurs downstream, stopping uncontrolled release of system media. They then reset when pressure equalizes. These valves eliminate the need for a complex bypass mechanism while reducing maintenance time.
Learn the differences between cracking pressure and resealing pressure to see if your check valve is working properly.
Check Valve Categories
Excess Flow Valves
Enhance system safety by preventing uncontrolled release of system media if downstream line ruptures with excess flow valves.
