Item In Stock
A manually-adjustable variable orifice, offering linear control with adaptability to a variety of adjustment operators (ordered separately).
In extreme clockwise position, valve is fully closed (normally closed). Counterclock-
wise rotation of 180° gradually increases flow. The fi rst 10° (approx.) of rotation is
deadband. The last 15° of rotation increases flow very little. For a normally-open
version with counterclockwise rotation gradually decreasing flow, consult factory.
NOTE: Use of the valve in the ➀ to ➁ direction is not recommended if the plastic knob operator is used. Because of the low effort (internal bearing used) adjustment,
flow forces may cause setting change. The valve will operate ➀ to ➁ well with handle-type operator kits.
• Ten-position detent or infi nite friction lock options.
• Good linearity in three flow range options.
• Adaptable to a variety of operators.
• Optional lock-down bracket.
• Heavy-duty construction.
• Low effort adjustment.
• Industry common cavity.
