Established in 1946, PK Valve became the first company housed in the Changwon National Industrial Complex in 1974. Since its inception, it has strived to grow into Korea’s number one industrial valve manufacturer handling every relevant process, from product development, design and modeling to testing, casting, machining, assembly, inspection, painting and packaging, on its own with an integrated production system.

High Pressure Forged Steel Valve

By selecting valve with a forged body the user automatically increases the safety and integrity of their plant and process equipment. It has long been known that forged valve are tougher, more resistant to impact, withstand higher induced pipe stresses and are more structurally superior to equivalent castings.

Ball Valve

The sealant injection system located on the body can be utilized in case of emergencies, o-ring damage, or if stem leakage occurs.

Cryogenic Valve

Cryogenic Gate Valves are specially engineered and designed for piping systems used in the storage and transport of liquefied gasses such as LNG and liquid nitrogen and oxygen. The main structural feature of these valves is an extended bonnet with an enclosed vapor chamber to isolate packing from the cryogenic fluid and thereby allow packing to function properly.

Parallel Slide Gate Valve

Parallel slide construction can be furnished for high differential pressure services or where thermal expansion may cause sticking of a wedge type. The parallel slide gate assembly consists of two interchangeable spring loaded discs, a fully guided disc holder, and retaining pins. Springs are fitted between discs to provide initial sealing force only, and do not maintain the sealing force.

Pressure Seal Valve

Pressure seal valve is intended for high pressure and high-temperature applications in all types of fluid, except where severe coking may occur. A selection of design and material would give excellent service in nuclear steam generating stations, industrial/chemical plants, and thermal power plants.

Bolted Bonnet Stainless Steel Valve

Stainless steel valve are utilized in the chemical, petrochemical, food, paper, and pharmaceutical processing industries all over the world. Stainless steel valve are designed and manufactured in conformity with API, ANSI, BS and other standards recognized with quality meeting the stringent requirements for such industrial applications.

Bolted Bonnet Cast Steel Valves

In the refineries, power plants, utilities and petrochemical/chemical process industries, PK cast steel valve have been regarded as of great importance about their excellent performance and reliability. By discriminatory blending of carefully selected materials combined with sound design and precision machining/assembly under strict quality controls, PK steel valve have gained general and wide acceptance.
