● Adjustable Stem Packing
Fully adjustable, field-replaceable stem seal system that meets international fugitive emission certification standards.
● Inspection Port Design- Field Replaceable Seat and Seal System
Field replaceable seats and seals extend the overall life of the valve, minimize downtime, and reduce the need for expensive non! current repairs or overall replacement.
● Metal-to-Metal Seals
Frictionless metal-to-metal seals are inherently fire resistant and fire tested, while meeting bi-directional zero leak requirements for a variety of critical applications.
● Tortoise Shell-Type Butterfly, Disc Shape
The butterfly disc Tortoise Shell-Type design achieves the best Cv/Kv value by maximizing flow and reducing resistance.

The low-temperature single-seat regulating valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
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.
