V- NOTCH BALL VALVE SERIES MIC -421

INTRODUCTION

The V–Notch Ball Valve gives non-clogging, high capacity,
straight through flow control of fluids containing pulp and
paper stock or slurries and fluids containing suspended
solids or fibrous materials. V-Notch Ball Valve is quarter
turn valve with a segment Ball. The V-Ball create a wedging
and shearing effect prevent the dragging of stock or slurry
between the ball and its seal the
V- Notch Ball Valves are offered squared and clamped
driven shaft plus ball shaft with splined connection
designed for zero lost motion for highly accurate
positioning and precise control.

V-NOTCH BALL VALVE

DESIGN FEATURES :

A Shearing effect between the ball and seal ensures tight shut-off, even on fibrous slurries.
The unrestricted, straight – through flow design provides high capacity and wide
rangeability.
Precise contouring of the V-notch balls provides a nearly equal percentage characteristic.
Replaceable ball seal and back up ring for added rigidity.
Ball machined to a super smooth finish, hard – chrome plated and polished to increase Ball
seal life.
High Cv to body size ratio.

QUALITY AND PERFORMANCE GUARANTEE :

Produced with Quality Systems accredited to ISO 9001: 2008 by Bureau Veritas.
Full material certification available for all major component Parts.
Full guarantee on design and Performance.
All testing are performed to the requirements of ANSI B16.34.

INSTALLATION

The valve should preferably be installed with actuator vertically above or below the valve body. It
can be installed in a horizontal or angled position if actuator is suitably supported. Necessary
clearance should be provided above the actuator to permit servicing. The flange bolts are to be
tightened evenly to avoid placing strain on the body. The inlet of air pressure regulator (Air set)
should be connected to the pneumatic supply line. Supply pressure to the diaphragm actuator
should be either 1.5 kg/cm² (20 psig) or 2.5 kg/cm² (35 psig) as per indication on the nameplate.
For cylinder actuator, supply pressure specified. For control applications, the air set and valve
positioner are mounted, piped and adjusted at the factory.

FINAL CHECK

After installation, check the valve operation for full stroke as indicated on the nameplate, check for
leaks in air line connection. Open and close the valve two or three times to ensure proper operation.
Before commissioning the process flow, it is essential to flush clean the piping properly. Ball valves
require minimum maintenance for its operation. Apply a few drops of oil on the exposed guides and
bushings, Hand wheel, if present, must be greased periodically

The Company’s policy is one of continuous product improvement and the right is reserved to
modify the specifications contained herein without notice.
