Klinger Westad Service & Spare Parts

Klinger Westad LNG butterfly valves are among the most widely used cryogenic valves on LNG carriers worldwide. WCS was the first independent company to give ship owners a genuine alternative for spares and service.

We service and supply the full range of Klinger Westad spare and actuator parts — including HQ limitswitch boxes, Acto distribution bars, and HQ/Acto cylinder seal kits — and carry out service and overhaul both on board and in dock. Our metal seals are manufactured in-house in Norway; we're also the only supplier of seals for older Klinger Westad gate valves the manufacturer no longer produces. Every WCS-manufactured part carries our 25% Price Guarantee against the OEM price.

Case Studies

From the workshop: documented Klinger Westad repairs

HQ Limitswitch Box: Worn Original to 316L Stainless Rebuild

The HQ limitswitch box pictured above came in after years of service in the marine cryogenic environment — worn to the point where the original was no longer fit to remain in service.

WCS reverse-engineered the part to the original dimensions and manufactured a direct replacement in-house in Norway, in 316L stainless steel — an upgrade in corrosion resistance over the original material, while keeping it a drop-in fit for the existing HQ actuator. The rebuilt box is covered by the same 25% Price Guarantee as the rest of our Klinger Westad range.

Acto Distribution Bar: Corroded Original to Newly Machined Replacement

The Acto distribution bar shown above was corroded after years in service — a common failure point on older actuators.

WCS machined a replacement in-house in Norway to the original specification, restoring a fully compatible, drop-in part without waiting on OEM lead times.

Manufacturer History

About Klinger Westad

Klinger Westad traces back to 1895, when Daniel Westad founded a valve manufacturing company in Geithus, Norway, originally serving the local pulp and paper industry. The company moved into marine applications around 1950, began building valves for LNG in the 1960s, and produced its first LNG butterfly valve in 1975 — pioneering the cryogenic butterfly valve technology still used across the industry today. Klinger Westad remains headquartered in Geithus and is now part of the international KLINGER Group.
