CARTER VALVE PRODUCTS

Isolation Valves

Isolation valves are designed to shut off flow safely and consistently—especially when leakage risk, cycling frequency, or harsh conditions make standard shutoff unreliable. We provide high-performance isolation solutions including butterfly valves (with advanced offset platforms such as our Hexa / six-eccentric concept), check valves for backflow prevention, and stop valves for secure on/off duty. Typical features include engineered sealing for tight shutoff, high-temperature capability, and options suited for demanding services such as molecular sieve, high-temperature FCCU, and cryogenic LNG isolation. This category helps you reduce unplanned leakage, simplify maintenance planning, and select an isolation valve that matches your plant standards and operating envelope.
