DN2400 Double Eccentric Butterfly Valve

This company produces the double eccentric softhearted sealing butterfly valve has simple structure, small flow resistance coefficient, difficult to stranded sundry drive torque is small, the advantages of simple operation,rapid, and it also has good flow regulating function and sealing performance at the same time, can achieve completely sealed, zero leakage gas test.

The different materials are used to make the sealing ring of different materials, which can be adapted to different media, working conditions, and make the cost and performance to the best effect It can be driven by worm wheel and electric power.it is mainly used for food, water, beverage, chemical, medicine, etc.

Features：

1.The tilted disc releases the compression of the disc sealing after a few degrees of opening resulting in low operating torque

2.The disc seal profile and rubber quality ensure low closing torques

3.All rubber parts are multi approved

4.Seal retainer ring of stainless steel

5.The threaded bolt holes in the disc are corrosion protected with O-rings

6.Machined and epoxy coated ductile iron seat integrated in the body

7.Shaft of stainless steel with self-lubricating bearings

8.The shaft ends are fully encapsulated in the disc and are fixed with dowels corrosion protected with O-rings and a stainless steel security plate. Key and keyway as backup

9.Replaceable shaft sealing with two EPDM O-rings on each side of a bronze bushing, and a flat NBR gasket

10.Optional locking device

11.DN 700-1600, body and disc coated with fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved, blue RAL 5017, according to WRAS-DVGW/W270/UBA,DN ≥ 1800, body and disc coated with 2-pack epoxy, blue RAL 5017 externally, ribbon blue or cream white internally, according to WRAS

12.Bi-directional operation up to DN2400 and uni-directional from DN2600
