High Performance Butterfly Valves
SIMMEL high-performance butterfly valve is a new type of butterfly valve designed based on the advantages of several different structural butterfly valves.
The sealing surface of the valve plate of this butterfly valve is a spherical arc body, and the sealing mechanism achieves a true dynamic seal through system pressure.
Therefore, it has excellent cutting performance, long service life, and low torque characteristics.
The product is suitable for various working conditions, especially for gas transportation.
In process media with high working temperature and high valve life requirements, the normal service life can reach about 1 million times.
The tighter the flange clamp on the insert outside the valve seat, the greater the pressure, and the better the sealing performance.
This butterfly valve has a unique product structure and ultra reliable sealing performance.

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
