Axial Flow Check Valve

RAYS PDS Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.

There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.

The low-temperature gate valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
