Features & Benefits

Core reason



The compression fit of the midline structure and elastic soft sealing surface (such as EPDM, PTFE) - the valve stem is centered to rotate the butterfly plate without eccentricity. When closed, the soft sealing surface is compressed by the medium pressure or the force of the actuator, forming a comprehensive and tight sealing contact with the valve seat, offsetting small errors, and achieving zero/micro leakage.

Core applicable media



Clean and particle free fluids such as water, seawater, air, natural gas, oil products (without particles), weak acid-base solutions (pH 4-10), etc. Key adaptation logic: Soft sealing materials (EPDM/PTFE, etc.) determine medium compatibility - EPDM is resistant to water, weak acids and weak bases, PTFE is resistant to strong acids and bases but not high temperatures, avoiding media containing hard particles (which can scratch the sealing surface) and strong oxidants (such as concentrated nitric acid).

Seat



The core advantages of the soft sealed center line clamp butterfly valve seat are reliable sealing (elastic fit without gaps), strong installation adaptability (clamp type does not require flange positioning), corrosion and wear resistance (compatible with high-quality soft materials such as EPDM/PTFE), and integrated structure (anti detachment), with low opening and closing friction (extending sealing life).

Stem



The valve stem is easy to disassemble and maintain (without the need to disassemble the valve as a whole), with higher sealing reliability (to avoid leakage at the valve stem through the shaft), high machining and assembly accuracy, suitable for large-diameter valves, and reduces the risk of deformation of long valve stems.

Actuators



pneumatic actuator or electric actuator

Controls



limit switch box, solenoid valve, Air filter pressure reducing valve, valve positioner
