ZECO forged valve refers to the blank of the valve, which is a forging piece with certain mechanical properties, shape, and size produced by applying pressure on the metal blank by forging and pressing machinery and then processed by ZECO manufacturing department on each side of forging piece. The main materials used for valve forging are carbon steel and alloy steel of various costs, followed by titanium, copper, and other alloys. The original state of forging is bar, ingot, metal powder, liquid metal, etc. Generally, the diameter of other forged valves on the high-pressure pipeline of ZECO forged valves is less than 2 inch except for some special conditions. Forged ball valves are also suitable for large diameters because ball valves are easy to process.

What is Forged Valve?

Forged steel valves are manufactured using a process called ‘forging’. Forging is based on the application of thermal energy to solid blocks of steel and then using mechanical forces to further process the steel into a finished product. This process is used to make valves that are extremely strong and tough. For example, Forged steel valves like forged steel gate valves are used in mining and mining processing, agriculture and livestock handling, aeronautics, automobile industry, brickworks, stormwater plants, rendering plants, asphalt plants, power and water industry, pharmaceuticals, chemical industry, cosmetic industry, and more.

Forged valve adopts the forging process because the mechanical properties of castings are lower than the same material of forgings, and forgings are formed by casting after forging processing of raw materials, the original casting internal loose grain structure, as a result of the forging force become more closely, make better continuity of metal fiber, plasticity and mechanical properties of the metal. ZECO is specialized in the production of forged valve factories, is one of the world’s many oil companies, gas companies, chemical companies, and energy companies, and so on industry, the company’s long-term strategic cooperation suppliers ZECO to constant innovation, continuous research, and development, and constantly improve the attitude of the highest performance to provide users with the most reliable products, and ZECO to create world famous brand, and let ZECO products used in the various countries well-known oil companies to provide users with reliable quality products for a long time.

What is Forged Steel Gate Valve?

Gate Valves have a low-pressure loss and fluid resistance and are used for ON-OFF service. They can be used in high-pressure services up to 4500Lb.

Special specification like cryogenic long bonnets, bellows seal, or electric actuator operation makes them suitable for multiple purposes.
