Soft Seal Butterfly Valve for rubber soft seal, double eccentric structure, this structure can reduce the wear of sealing surface, reduce Valve Torque, improve the service life of sealing surface.
As the seal of stainless steel to rubber, so good sealing performance, for two-way zero leakage valve, rubber sealing ring with interchangeability, easy and simple replacement.
Soft Seal Butterfly Valve with compact structure, open and close quickly, reliable sealing performance, portable labor-saving, long life, easy maintenance.
Due to the double eccentric seal structure of the Manual / Electric Soft Seal Butterfly Valve, when the valve is fully open, the disc seal ring is in a relaxed state; when the valve is closed, the seal ring is squeezed by the sealing surface of the valve body and the disc plate, resulting in elastic deformation, this elastic deformation is the valve sealing surface between the sealing force gradually reached the maximum, and its characteristics are as follows:
1. The Soft Seal Butterfly Valve opens and closes quickly.
2. The Soft Seal Butterfly Valve uses the advanced double eccentric seal structure, the friction is small, the seal performance is good.
3. The Soft Seal Butterfly Valve seal ring and the valve body precise coordination, effectively avoids the medium to scour, enhances the service life and the seal effect.
4. Soft Seal Butterfly Valve plate sealing ring material is high-quality rubber, sealing ring has good anti-aging, anti-wear, long service life.
5. Soft Seal Butterfly Valve switch limit device is reliable, no over-open, clearance phenomenon, switch indication and disc actual position consistent.
6. The electric device has over-torque device, stroke control structure of counter, in-place indication and remote contact, two pairs of normally open and two pairs of normally closed contact, and full-open and full-closed contact, which can meet the requirements of in-place and remote control. Electric device can accept three-phase four-wire system 380 / 220VAC. The Electric Device can withstand 2 times the required torque without permanent deformation and damage. Manual and electric switch mode is the automatic operation mode with electric priority.
7. Soft Seal Butterfly Valve’s body, disc, stem with sufficient strength and stiffness, disc seal ring installed in the valve body to adjust and replace.
