● Top-Mounted Design: Facilitates easy maintenance directly in the pipeline, reducing downtime and costs, and increases durability.
● Advanced Seal Design: Features a floating seat for reliable sealing at all pressures and includes fire-safe components.
● Emergency and Regular Lubrication: Allows for emergency sealing and regular lubrication through a built-in grease valve to ensure
smooth operation.
● Extended Stem: Offers customizable stem lengths for ease of maintenance, especially in underground installations.
● Anti-Static Safety: Built to prevent static buildup, meeting API6D and ISO17292 standards.
● Dual Block and Bleed: Capable of isolating both upstream and downstream media, with automatic pressure relief for safety.
● Low Torque Operation: Designed with a fixed ball and sliding bearings to reduce friction and ease operation.

The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
The Cryogenic Temperature and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
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.
