Product Features
 

1.GGG40/50 Ductile Iron Body & Disc allows high impact and streching resistance
2.With Full Bore design, ensures minimized pressure loss and increased energy efficiency
3.Maintenance free valve design
4.Fully EPDM vulcanised wedge maintains full stop of flow and can absorb smaller particules in the flow. (NBR coated wedge is optional)
5.Stainless steel stem with threads for high strength
6.Maintenance-free and corrosion-resistant multi stem O-rings ensures higher durability
7.Brass wedge nut provides fixation of the stem and low torques.
8.With isolated bonnet nuts, no risk of corrosion
9.Bidirectional use. Possible to install on horizontal and vertical pipelines with varied flow directions
10.Fixed wedge structures prevents vibrationWith precise machined stem, ensures low torque requirements during operation
11.Full coating on the body and disc internally & externally with an average of 250 microns. Higher coating thicknesses are available when required.
12.WRAS approved coating available upon request which meets hygienic requirements for potable water applications
13.For big size valves, balanced positioned lifting holes on the body ease transportation and installation
14.Suitable for vacuum conditionsSuitable for shut-off and isolation purposes. 
15.Not suitable for regulation purposesElectrical actuator connection is done with an intermediate top flange arrangement
16.Suitable to use with above-underground applications. 
17.Can be operated with handwheel, gearbox, actuator and spindle.
