● Sealing Efficiency: Equipped with lip-type seal seats for excellent sealing, low friction, and minimal operational torque.
● Stem Safety: Features a bottom-mounted stem to prevent blowout and maintain seal integrity during fires.
● Fire and Static Safety: Includes fire-safe and anti-static features, suitable for soft-sealed valves.
● Accurate Handle Indicator: The flat-headed stem ensures that the handle's position accurately reflects the valve's status.
● Locking Mechanism: Locking holes at fully open and closed positions prevent accidental operation.
● Design Benefits: These valves are quick to operate, compact, lightweight, easy to maintain, and work smoothly with minimal fluid resistance and noise.

The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
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 hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
