Features:

1. Valve body and seat are adopted with split design for easy maintenance and replacement.

2. After machining of valve body, because of without lining rubber, to avoid the pressure deformation of the lining rubber. Which ensure the accuracy of body symmetry and reduce the torque of butterfly valve.

3. valve stem and valve body are equipped with 4 oil proof bearings, which is beneficial to stem support. the upper shaft hole is equipped with two O rings and one special rectangular screw ring water seal, which makes the axial seal more reliable.

4. The two ends of the valve plate shaft hole are designed with grooves, which can effectively prevent damage of valve seat caused by the excessive extrusion when valve shaft is loaded into valve the to ensure the sealing of the valve seat end face and the valve plate.

5. After quenching and tempering process, the pin material of butterfly valve has high strength and high corrosion resistance, and the connection is more sate and stable.

6. A non-pin stem adopts an anti-exit structure, spring + type card structure are used in the upper part of the stem, which can not only compensate for installation errors, but also prevent the stem from loosening.

As a premier industrial valve manufacturer, TWIV FLUID VALVE engineers reliable flow control components tailored for global fluid distribution and municipal utility networks. Our high-efficiency cast iron wafer type butterfly valve range is specifically designed to provide robust bi-directional sealing performance in space-restricted piping systems. Featuring a lightweight and compact concentric body profile, this resilient-seated valve ensures simple, secure alignment between standard ANSI or DIN pipe flanges, significantly reducing structural stress and lowering international shipping costs for bulk procurement.

The 4 inch wafer butterfly valve body is cast from high-tensile gray or ductile iron, providing excellent mechanical integrity and pressure boundary stability under consistent service conditions. To fulfill the exact technical demands of localized piping networks, this specialized butterfly valve dn100 pn16 configuration supports standard commercial pressure ratings up to 16 bar. It incorporates a heavy-duty lever butterfly valve manipulation mechanism with an ergonomic positioning notch plate, giving commercial pipeline operators smooth, rapid quarter-turn throttling manual control and reliable disc positioning.

Operational longevity is achieved through a premium butterfly valve epdm seating liner. The high-grade vulcanized EPDM resilient seat completely envelops the inner flow path, preventing internal body erosion while establishing tight, zero-leakage shutoff parameters across commercial HVAC, cooling water, and general wastewater treatment applications. Each manufacturing run at our factory undergoes strict hydro and pneumatic seat pressure testing prior to container dispatch to ensure flawless field performance.
