The SBWG model is suitable for use with Butterfly, Plug and any other type requiring quarter turn motion for thrust and torque applications
High Tensile Aluminium bronze material providing corrosion and abrasion resistance
Castings are Ductile Iron, class 65-45-12 providing high strength and impact resistance
Housing Covers have “Close-Open-Close” cast directly on the cov-er witch permits operation in either clock or anti clock close direc-tion with position indication
Also the pointer and easily be repositioned and adjusted with ease if required
All units are furnished with removable splined bushings to permit accurate position between the gear drive and the valve shaft
The drive sleeve is furnished with hardened steel thrust washers above and below the worm gear that minimize fiction loose between the gear and ductile iron castings
Gears are machine cut, heat treated and ground for optimum operation
The unit is completely O-Ring sealed suitable for temporary submersion to meet IP68 Class
External Adjustable Stopper bolts allow for easy position accuracy of +/-5°. Each bolt also includes Buna-N sealing washers to pre-vent waster ingress
This series of Worm Gears range from 310Nm to 540,000Nm with larger models available upon request
Many options are available, such as hand wheels, chain wheels, position dial indicators, vertical input.
TECHNICAL SPECIFICATION
Construction: Ductile Iron Temperature Range: -40°C to +90°C Coating: AS4158 (Jotun) Mounting Flange: ISO5211 Enclosure Rating: IP68
APPLICATIONS Challenger Valves and Actuators are the “Right Choice for Valves and Actuation” when quality matters. Servicing a variety of industries such as: Water & Waste Water, Treatment Plants, Sewage and Sludge Systems, in addition can be used on a flow control or isolation valve.
These three small models of SBWG will cover most valves below 300mm that require quarter turn motion.
Can be adjusted for both clockwise close or anti clockwise close operation (except the SBWG-BF)
This unit does not include a reduction box so the input torque and number of turns to open and close are minimal for quick and easy operation
Many options are available such as Hand Wheels, Key Caps, Chain Wheels, Limit Switches, Extension Spindles, Actuator Ready Mounting Pads and many more.
Incorporates the use of a single reduction to lower the input torque while keeping the number of turns to open and close low.
Can be adjusted for both clockwise close or anti clockwise close operation.
Many options are available such as Hand Wheels, Key Caps, Chain Wheels, Limit Switches, Extension Spindles, Actuator Ready Mounting Pads and many more.
Removable spline bushing to permit accurate positioning between gear drive and valve stem
