Product Details: Flange Center Line Lining Rubber Butterfly Valve With Worm Gear

Rubber Butterfly Valve Product Structure Features:


1. Top flange: standardized drive device flange, conforming to ISO5211


2. Body: Ductile iron and other applicable materials are used.


3. Plate: The streamlined valve plate effectively reduces pressure loss and flow loss. The edge of the valve plate is spherically processed and hand polished. It has the characteristics of low operating torque, long valve seat life and good sealing performance. It can be selected according to a variety of media materials.


4. Rubber valve seat: one-piece valve seat, suitable for all for all kinds of working conditions, extremely low torque value, wide rubber surface and flange joint surface at both ends of the valve, no special flange for clamping butterfly valve, rubber seat for installation bonding to the valve body is more suitable for pipelines with higher vacuum degree to avoid the valve seat moving and deforming due to the vacuum negative negative pressure of the pipline.


5. Valve stem: Central type integral valve stem design, two-way sealing without leakage, installation without restriction of flow direction.


6. Shaft sleeve: copper alloy, more wear-resistant and effectively reduce torque.


7. "O" ring: NBR nitrile rubber, effective dust proof and internal leakage.


8. Pin: conical pin, which can effectively transmit torque and effectively seal without leakage.
