Area of application:
Easy to use, robust components to be used under a variety of conditions:

Butterfly valve with one flange (F1):
For applications requiring flexible connection to subsequent elements (via rubber or fabric sleeve).
To be used, for example, between silo and scale, sieving machine etc.

Butterfly valve with two flanges (F2):
For applications requiring force-fit connection to subsequent elements. To be used, for example,
between silo and screw conveyor, rotary valve etc.

For both basic units, three operation modes are available:
a. Electric-pneumatic drive
b. Gear motor drive
c. Manual operation


Material/Layout:
Body: cast aluminium
Valve plate: GG with neoprene-rubber coating
Shaft extension: C 40 with self-lubricating plastic bushes that do not get in touch with the product

F1: flange on one side + sleeve connector
F2: flanges on both sides

a. Electric-pneumatic drive:
EP 80 - EP 100 - EP 125 = piston diameter

b. Gear motor drive:
Gear motor: Size GM2: 0,55 kW
Gear motor: Size GM2: 0,75 kW

c. Manual operation:
H2: Hand lever 300 mm long
H3: Hand lever 500 mm long
Change of operation mode quickly and easily possible.

Technical data:
Dust-proof: alternatively pressure-tight up to 0,2 bar
Sealing ring: nitrile rubber (NBR black), temperature-resistant between - 30 °C and +130 °C,
not to be used for foodstuff

Advantages:
• physical properties: Very resistant against oils, and heat
• mechanical properties: very flexible, hardly deformable, very low gas permeability
• chemical properties: resistant against mineral oils, hydrocarbonate, water, steam, gases and vegetable oils
