Installation Steps
(1) Proper bracket must be made in order to attach positioner on
the actuator yoke.
Please consider following when making a bracket.
① Feedback lever should be leveled at 50% of valve stroke. (Refer
to Step 7)
② Feedback lever connection bar of actuator clamp should be
installed at the position that the valve
stroke and numbers which indicated on the feedback lever must be
fitted. (Refer to Step 8)
(2) Attach YT-1000L to the bracket, which was produced in earlier
step, by using bolts. Please refer to backside of the product
for size of bolts. The standard size of bolt is M8 X 1.25P, and
other bolt sizes are available. Please contact YTC sales
department.
(3) Attach YT-1000L (with bracket) to the actuator yoke - DO NOT
TIGHTEN COMPLETELY.
(4) Connect YT-1000L feedback lever to the actuator clamp. The gap
on the YT-1000L feedback
lever is 6.5mm. The connection bar thickness should be less than
6.3mm.
(5) Connect air filter regulator to the actuator temporarily. Set
supply pressure of the regulator in order to position the actuator
clamp at 50% of valve stroke
(6) Insert connection bar into the YT-1000L feedback lever. The
connection bar should be inserted at the 50% point on the feedback
lever, which would help to reduce hysteresis.
(7) If connection bar does not point at 50% point, then adjust
bracket or feedback link bar position. Failure to position at 50%
would lower the linearity of the positioner.
(8) Check valve stroke. The stroke numbers are indicated on the
feedback lever. Position
connection bar at the number on the feedback lever according to the
valve stroke. To adjust, move the bracket or connection bar.
Quality Standards
The company for the products are brand new original products, no
second-hand and refurbished products, or leave a compensable ten
and return the full amount, but the buyer due to our purchase of
model error is not responsible for returns, another of the
company's sales of products enjoy one year from the date of
shipment quality assurance, according to the original quality
standards, during warranty with product problems, need confirmation
testing by the manufacturer, the supplier to be solved, the demand
side due to storage, use, poor maintenance caused by lower-quality
product, and not raise objections.
