Forged Ball Valve

Introduction

Product Introduction

LYV®️ Forged ball valve refers to a valve that uses the process of forged steel. In fact, the difference is in material, forged steel valves are often used in high temperature and high pressure conditions. There are commonly forged steel gate valves, forging steel globe valves, forged steel check valves, forged steel ball valves and so on. Forged valves are usually suitable for small size valves, with a range of 1/2” ~ 4″and pressure ranges of 150LB ~ 4500LB.

Features

●The hot forgings of forged valves improve recrystallization and grain refinement, thus contributing to the maximum possible strength and uniformization of the material.

●The contours of the valve body surrounded by grains to reduce metal fatigue.

●The forged valve body eliminates internal defects and harmonizes the metal structure for optimum performance.

●External pressure is the biggest problem for the impact between grains, but forging significantly reduces the occurrence of this problem and significantly increases the life of forged valves. Bi-directional tight shut-off

●The control of the dimensional consistency of the closed die forging of the forged steel valve has no defects caused by the displacement of the casting. Double block & bleed (DBB) / Double Isolation & Bleed (DIB)

●The ability of forging steel to fully meet the needs of most designs is the most important advantage. Low operating torque design

●Because of the above factors, forged valves have become indispensable products in the petroleum, chemical, pharmaceutical and high-demand power industries.

●Anti-blowout stem design

Why choose LYV®️ valves:?

We produce Forged ball valve for over 30 years. The workshop covers 13000 square meters and own more than 50 advanced CNC machines. Our engineers & production team will make sure your order delivers with high-quality and fastest time. We also care about valve shipping. The valves will wrap by bubble pouches or paper to ensure the paint will not be damaged. We also fixed valve by plywood stick after we put valve into the box. The plywood case will be painted with necessary marking to make sure the valve will not be damaged during shipping.
