14 Series EN593 Double Eccentric Flanged Butterfly Valve
Product Description
Double Eccentric Resilient Seated Butterfly Valve is one of the main product type preferred in water networks. Through its disc design where the center is shifted in two axis, this leads to a big improvement on decreasing operation torque values, lowering the friction on disc sealing area and extended service life.

Main Parts material and Dimensions Product Features
1.GGG40/50 Ductile Iron Body & Disc allows high impact and streching resistance
2.Double Eccentric / Double Offset Disc Design
3.Resilient Seated Type
4.Disc sealing ring EPDM as default. NBR or VITON options are available
5.Block moulded solid/one-piece T-shaped disc sealing ring extends drop-tight sealing life time
6.Easy to replace disc sealing ring without dismantling the valve from the pipeline and without disman tling the disc from the valve itself just by taking out the retaining ring through its bolts. lit is easy to replace the disc sealing ring without any additional equipments
7.SS304/316 grade stainless steel welding seat on the body is manufactured through automatic welding machines and microfinished precise milling operation. When disc is fully dosed, disc sealing ring applies equal pressure on every point on the welding seat.
8.Drop-tight dosure
9.Double O-ring feature on both shafts ensures high sealing
10.Shafts are equipped with bronze bushingshaving high corrosion resistance
11.Ensures minimized pressure loss and increased energy efficiency with double shaft design
12.Easy to operate with self locking gearbox equipped with mechanical indicator
13.Low torque requirements during operationEasy to install on the line, light weight and occupies less space
14.Full coating on the body and disc internally & externally with an average of 250 miaons. Higher coating thicknesses are available when required.
15.WRAS approved coating available upon request which meets hygienic requirements for potable water applications
16.Maintenance free design for the valve and gearbox
17.Default operation is gearbox with ISO top flange ready to connect electrical actuator. Pneumatic actuators can be installed directly on the top flange of the valve itself.
18.Double Eccentric Butterfly valves are deisgned bi-directional according to EN1074-2. For proper installation, direction arrow on the body should be considered.
19.Operation with extended spindle version is also available
20.Balanced positioned lifting holes on the body ease transportation and installation
21.Hydrostatic test pressure for seat: PNX 1.1, for shell: PN X 1.5 according to EN 12266-1.
