Chain Wheel Perspective

Although the basic purpose of all chain wheels is the same - ground level control of overhead valves - operating conditions can vary widely. Specifiers must consider such matters as accessibility, corrosion factors, frequency of use, and for fail-safe reasons the possible need for an impact operator. Due to these operational variations, Roto Hammer Industries offers the widest range of chain wheels available today. For a majority of applications the CL series clamp-on model is the most cost-efficient. For long wear in high frequency applications we recommend our premium clamp-on C-Series. To provide an integrated valve application, the Roto Hammer direct mount premium E-Series may be preferred.

Chain operated model

For valves that tend to stick or are otherwise difficult to operate, or in those cases where fail-safe operation is critical, the RotoHammer M-Series Impact Operator is recommended. Its function is to deliver a quick measured blow, similar to that of a hammer striking an anvil, to either open or close the valve. M-Series models may be chain or handwheel operated (as shown above). Clamp-on or direct mount (adapter) versions are available.
