1. Small in size, light in weight, compact in structure, easy in maintenance.

2. Two torsion spring are used on each of the pair valve plates,which close the plates quickly and automatically.

3.The quick-close action prevents the medium from flowing back andeliminates water hammer effect, protect the pump.

4.Short body structure and good rigidity.

5.Safe and reliable in operation, high anti-interference performance.

1.Good coverage and precise geometry size, to ensure reliable sealing andlonger service life.

2.Using non toxic epoxy resin coating to prevent corrosion and rust, canbe used in the sewage system.

3.Stem o-rings seals, low friction, no leaking.

1. Small volume and flow resistance, easy installation and dismantling
2. Short structure design, saving raw materials and installation space
3. With lifting wedge design, sundries on the sealing surface can be automatically cleared up
4. Special value for slurry medium pipe

Investment castings for body and cap.

1. Advanced structure and low resistance for strong drain capacity
2. Protect the normal use of valves and equipment
3. Easy installation and maintenance.

1. The rubber joint can greatly reduce pipeline system vibration and noise, can solve the problem of joint displacement, axial expansion, etc.
2. According to different materials, it can be made into many kinds, adapt to many mediums and different environment.
3. Good sealing rubber, light weight, easy installation, long service life, and avoid contacting with sharp metal device.
4. If use overhead, can match with elastic support.If pipeline pressure is high, should use bolt connect the flange both ends.

1. Easy installation and dismantling
2. Adjustable length for installation and dismantling
3. The axial force action protects the safe operation of pump, valve and other equipments

Handles are available for on/off and throttlingcontrol of butterfly valve. The handles can be used for DN25 to DN300(1’’ to 12’’)concentric type butterfly valves. For valve large than 12’’, gear operator isrecommended. Meanwhile, the rugged construction of concentric type handlesmakes them ideally suit for manual actuating small valves. The notch platepermits the valve can be locked in any of the 10 position on handle.
