Adjustable pitch MVL

Features

• HVAC applications
• Designed for applications up to 5 Hp
• Bore range 1/2" to 7/8"
• Bulk packaged 20 per carton
• Designed to be used with the MFAL series

Note: DO NOT use B gripnotch belt ratings with MVL sheaves.

Pulley adjustment

Modify the sheave pitch diameter by rotating the adjustable flange on the threaded hub of the pulley. Once the required diameter is obtained, tighten the adjusting screw(s) on one of the two flat surfaces.

Adjustable pitch sheaves

Adjustable speed sheaves are used primarily in the air handling industry. Optimal fan working speed is easily obtained by simply adjusting one of the pulleys.

• Adjustable pitch sheaves are made of durable gray cast iron class 30.
• Line covers from fractional light duty (less than 1 Hp) to heavy duty (40 Hp) applications

Note: DO NOT use these gray cast iron sheaves with rim speeds in excess of 6500 feet per minute. Note that the maximum RPM indicated on the arm of the sheave is based on the 6500 ft./min. limit, and doesn't take into consideration the need for dynamic balancing (two planes). Please verify the validity of dynamic balancing in your application. All operational PT products when used in a drive are potentially dangerous and must be guarded by the user as required by applicable laws, regulations, standards and good safety practice. (Refer to ANSI standard B15.1)
Irregardless of the equipment used, Dodge Industrial recommends NOT reboring adjustable pitch pulleys. The concentricity may be lost.
