# PK Valves

*Let us help you with*

PK Valves use the same metal-to-metal sealing technology found in Klinger Westad and KSB Amri LNG butterfly valves. WCS is now entering the market for PK valve seals as well.

This is our newest valve line — we're building out parts and service coverage starting with metal seals in the 400–550 mm range, with more sizes to follow. Contact us to check availability for your specific valve.

## About PK Valves

PK Valve was established in Changwon, South Korea, in 1946, and became the first company to move into the newly created Changwon National Industrial Complex in 1974. Over more than seven decades it grew into one of Korea's leading industrial valve manufacturers, developing cryogenic and butterfly valve lines used in LNG, petrochemical, and power-generation applications in more than 70 countries. Its metal-to-metal sealing butterfly valves use the same underlying technology as Klinger Westad and KSB Amri, which is why WCS has been able to extend its in-house seal manufacturing to cover PK Valves as well.
