 Watertight housings sealed with "O" rings and gaskets. - Ball or tapered roller bearings ensure a high degree of reliability and mechanical efficiency.
- For larger gears over 18,000 in-lbs, the tapered roller bearings handle high axial thrusts transmitted to the body by the worm screw.
- Sealed adjustment screws prevent grease from leaking out and debris from penetrating the housing for buried and submersible applications.
- Self locking and high efficiency.
- Splined adapter bushings are used to aid in the customization of each gear to fit all shapes of valve stems faster and with reduced cost.
- Handwheels are keyed to the input shafts for a tight, firm fit.
- Handwheels are cast ductile iron in lieu of fabricated tube. This better supports clamp-on chain wheel operators and assists in the ease of operation due to increased mass.
- 410 stainless input shafts to protect against rust corrosion.
- Highly visible indicators assist to view open versus closed orientation.
- Factory tapped mounting bracket holes accommodate field installation of limit switches, beacon style indicators, etc.
- NAMUR designed indicator positioning slots accommodate direct mounting of switches.
- Lubrication for life ensures maintenance free service
- Optional locking devices available.
