GKV-133 Series Stainless Steel Ball Valve Welded End Complies With ISO 5211

The GKV-133 series valve can be made of precision cast CF8M (316L) stainless steel or WCB carbon steel material, and adopts a swing type middle valve body design for easy online maintenance.

All valve body castings are engraved with the foundry heat number,

achieving full process traceability and ensuring quality and reliability.

For manually operated valves, the GKV-133 series valve is equipped

with a stainless steel safety locking handle and limit device, which limits

the rotation angle of the handle to 90 °.

Other features of the GKV-133 series welded ball valve include replaceable

seat and stem packing, easy maintenance, and extended service life.

The integrated ISO 5211 installation platform can achieve precise alignment,

simplifying the installation of actuators, gear operating devices, and other

execution and control accessories.

Unique design of GKV133 full bore welded ball valve

The GKV-133 series full bore, three piece ball valve is designed to offer all

the advantages of a three piece ball valve at an economical price, including

heavy-duty, internal inlet anti spray valve stem, and adjustable live load

packing, ensuring zero leakage, low torque, and extended service life.

The GKV-133 series valves are available in two types: investment cast CF8M

(316L) stainless steel or WCB carbon steel. All body castings are marked with

casting furnace numbers to achieve full traceability, ensuring quality and

reliability.
