The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.
Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature
differences, ensuring a reliable seal.
The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.
It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.
The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.

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.
浙江欧菲钢制球阀的设计制造保证了最大的使用寿命和可靠性。所有球阀完全满足美国石油协会标准 API 608 & API 6D 和英国标准 BS 5351 的设计要求，并符合美国机械工程师协会标准 ASMEB16.34。
