DiamondV offers the following advantages:
- Substantial torque reduction due to > 10 friction (metal on metal)
- Torque breakaway reduced by 30% to 40%
- No corrosion, sticking, media, wear or galling
- Ideal for gas, refractory, pulp and paper service
- Eliminates valve & packing leaking, torque increase due to premature wear
- Replace sellite with 316 S.S for bearing
- Extends valve life by 2 to 3 years and operate at tempature over 575 degree F
- Cost of ownership saving over 50% with substantial maintenance and spare inventory cost reductions
