DESCRIPTION

A manually-adjustable variable oriﬁ ce, offering linear control with adaptability to a

variety of adjustment operators (ordered separately).

OPERATION

In extreme clockwise position, valve is fully closed (normally closed). Counterclock-

wise rotation of 180° gradually increases ﬂ ow. The ﬁ rst 10° (approx.) of rotation is

deadband. The last 15° of rotation increases ﬂ ow very little. For a normally-open

version with counterclockwise rotation gradually decreasing ﬂ ow, 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,

ﬂ ow forces may cause setting change. The valve will operate

➀ to ➁ well with

handle-type operator kits.

FEATURES

• Ten-position detent or inﬁ nite friction lock options.

• Good linearity in three ﬂ ow range options.

• Adaptable to a variety of operators.

• Optional lock-down bracket.

• Heavy-duty construction.

• Low effort adjustment.

• Industry common cavity.
