Full Lining Rubber Butterfly Valve EN593 With Worm Gear

Double Eccetric Butterfly Valve Product Structure Features

1. Connecting bracket: standardized driving device flange, complying with ISO5211
2. Sealing gland
3. "V" type sealing ring: NBR nitrile rubber, 4-6 pieces, effectively preventing the upper end of the shaft from leaking and the sealing is adjustable.
4. Body: Ductile iron.
5. Plate: the eccentric structure is adopted, and the sealing pressure ratio between the sealing pairs is automatically established to reduce the friction of the sealing ring and extend the service life of the valve..
The streamlined double eccentric valve plate effectively reduces the pressure loss and flow loss. The valve plate sealing ring adopts the "T" structure, and the sealing pair is linear sealed, with the characteristics of small operating torque, long service life of the sealing ring and good sealing performance.
The sealing ring can be replaced.
6. Seat: Inlaid or surfacing welded stainless steel valve seat, strong anti-scouring ability.
7. Stem: eccentric double half shaft stem design, less flow resistance.
8. Shaft sleeve: copper alloy, more wear-resistant and effective to reduce torque.
9. Pin: cylindrical pin, which can effectively transfer torque.

Double Eccetric Butterfly Valve Sealing Structure and Characteristics 

1. The "n"type stainless steel belt is inlaid on the valve body, which can prevent corrosion for a long time, and can prevent the vibration caused by the unstable water flow speed, and the valve failure caused by the losening and falling off of the fasteners, thus improving the adaptability to the adverse working
conditions.
2. The adoption of reliable "O" ring not only saves materials, but also simplifies the process and greatly reduces the cost of products.

Product Advantages

Enhanced Sealing and Low Torque Operation

The Full Lining Rubber Butterfly Valve utilizes a double eccentric structure that ensures minimal friction and smooth operation. The butterfly 

valve also features an adjustable "V" type sealing ring that maintains a reliable seal, even under varying pressures. This results in long-lasting 

performance and reduces the need for frequent maintenance.

Superior Corrosion Resistance

The valve’s stainless steel inlaid seat and copper alloy shaft sleeve provide excellent resistance to corrosion, making it suitable for aggressive 

environments such as sewage systems and marine applications. The added corrosion protection extends the valve's lifespan, reducing replacement

 costs.

Cost-Effective and Energy Efficient

The streamlined design of the valve reduces pressure loss, optimizing energy efficiency. The low torque required for operation also decreases 

energy consumption, making the high-performance butterfly valve a cost-effective solution for large-scale industrial applications. Additionally, 

the reduced wear on components ensures minimal maintenance, lowering long-term operating costs.
