LOCKSHIELDS WITH FLOW METER
FLOW REGULATION AND ISOLATION DEVICE WITH SET CALIBRATION
MEMORY AND REGULATED FLOW DISPLAY SYSTEM.
SIMPLE, DIRECT CALIBRATION BY MEANS OF INDICATOR THAT
DISPLAYS THE CIRCUIT FLOW.
THE SPECIAL DESIGN ALSO MAKES IT POSSIBLE TO CLEAN THE WIN-
DOW OR REPLACE THE ENTIRE MEASUREMENT COMPONENT WITHOUT
DRAINING THE SYSTEM.
• MEASUREMENT FIELD 0-4 l/min
• INDICATION ERROR ± 10% OFF SCALE
• MAX WORKING PRESSURE 6 bar
• MAX WORKING TEMPERATURE 90 °C
• PRESSURE DROPS Kv from 0,15 (1 l/min)
to 0,55 (4 l/min)
• MAX PRESSURE DROP (OFF SCALE) Kv = 0,9

ADJUSTMENT
THE ADJUSTMENT OPERATION IS CARRIED OUT IN THE FOLLOWING WAY:
FIRST RAISE THE WHITE RING NUT. THE ISOLATING FUNCTION IS
SUPPLIED IN THE FULLY CLOSED POSITION. CARRY OUT THE FOLLOWING
ACTIVITY UNDER FLOW CONDITIONS. NOTE, IT IS NOT NECESSARY TO
USE TOOLS WHEN ADJUSTING, ONLY WHEN SERVICING.
1. TURN THE RING NUT A, ANTICLOCKWISE UNTIL THE LOCKSHIELD
ISOLATOR IS COMPLETELY OPEN.
2. LOWER THE RING NUT A, AND CALIBRATE USING THE ADJUSTER B,
UNTIL THE CORRECT FLOW IS REACHED (DIRECTLY INDICATED BY THE
LOADING CAPACITY FLOW SCALE IN THE CLEAR WINDOW).
3. RAISE THE RING NUT A, UNTIL IT CLICKS, INDICATING THAT IT IS IN
THE CORRECT POSITION.
IT IS ALSO POSSIBLE TO SEAL THE RING NUT INTO THIS POSITION USING
A LEAD SEAL AND THE HOLES IN THE VANES C TO FASTEN IT:
• DIRECTLY TO THE MANIFOLD, PREVENTING AND TAMPERING
• TO THE FLOW METER, MAKING IT POSSIBLE TO INTERCEPT THE FLOW
WITHOUT CHANGING THE SET CALIBRATION FOR MAXIMUM OPENING.
CLEANING THE WINDOW
• TURN THE RING NUT, A, CLOCKWISE, UNTIL THE LOCKSHIELD ISOLA-
TING FUNCTION IS COMPLETELY CLOSED
• REMOVE THE WINDOW BY SECURING ADJUSTER B,
AND USING HAND PRESSURE OR A 17 mm RING SPANNER, REMOVE
THE WINDOW GENTLY.
• CLEAN THE WINDOW AND SCREW IT BACK ON.
• TURN THE RING NUT, A, ANTI-CLOCKWISE, UNTIL THE LOCKSHIELD IS
COMPLETELY OPEN
