Features and advantages

· The design of the clamp and ear type valve body, with structural length dimensions in accordance withEN 558 20Series andAPI 609.

· Design standards comply withEN 593andAPI 609.

· The valve seat can be replaced and can isolate the valve body and stem from the flowing medium.

· The sealing force of the valve stem exceeds the rated pressure of the valve, effectively preventing the leakage of overcurrent medium through the valve stem to the external environment.

· The second stage valve stem seal serves as a backup seal to ensure greater safety and reliability.

· The two ends of the valve seat are molded on the bodyOThe ring can replace the gasket as a flange seal.

· The valve stem sealing ring can prevent water vapor from seeping into the valve stem area.

· The dual valve stem enables the thin valve plate design to leverage its low flow resistance characteristics(Can be reachedDN 300).

· The circular polished valve plate edge ensures concentric sealing, lower torque, longer seat life, and bubble level sealing of the valve.

· The valve body positioning hole is easy to install and suitable for centering between flanges.

· The extended valve body neck achieves pipeline insulation.

· The upper and lower valve stem bearings provide good support, and minimal friction ensures low torque of the valve.

· The top liner can absorb the axial thrust load on the actuator side.

· All valves comply with'Pressure equipment instruction'(97/23/EU) B1+D，CEidentification.
