Motorised Butterfly Valves

Motorised Butterfly Valves Supplier-GNEE

Butterfly valve has a simple structure, small point volume, light weight, material consumption, small installation size, rapid switching, 90 ° reciprocating rotary, driving torque is small, etc., used to cut off, connect, adjust the pipeline medium, has a good fluid control characteristics and closing sealing performance. Butterfly valve in the fully open position, the butterfly plate thickness is the resistance of the medium flow through the valve body, so the pressure drop generated by the valve is very small, so it has a better flow control characteristics. Butterfly valve has two types of sealing: elastic seal and metal seal. Elastic seal valve, the seal can be set in the valve body or attached to the periphery of the butterfly plate.

Electric butterfly valves Specification

● One-piece cast flapper limiters position the flapper perfectly in the seat for maximum seat and seal life.

● Unique packing design allows use under pressure and vacuum without modification or special assembly.

● Rocker shaped gland bridge compensates for uneven adjustment of the gland nut and reduces packing leakage.

● Flat body holes at journal ports locate the shaft bearing near the disk, providing maximum shaft support, which reduces wear and extends service life.

● All valves come standard with blowout-proof shafts for added safety.
