ELECTRICALLY ACTUATED TWO-WAY DUAL BLOCK®
REGULATING BALL VALVE
• Joint system for solvent welding (PVC-U only), for welding (PP-H and PVDF only),
for threading and flanging
• Patented SEAT STOP®ball carrier system that lets you micro-adjust ball seats
and minimise the axial force eect.
• Easy radial disassembly allowing quick replacement of O-rings and ball seats
without any need for tools
• Radial dismounting valve body (True Union) made for PVC-U, PVC-C and
PVDF-H injection moulding equipped with built-in bores for actuation. ISO 9393
compliant test requisites
• Option of disassembling downstream pipes with the valve in the closed position
• High surface finish stem with double O-Ring and double groove ball connection
• Integrated bracket for valve anchoring
• Ball seat carrier can be adjusted using the Easytorque adjustment kit
• Actuation option: version with electric modulating actuator with 4-20 mA /
0-10 V inlet and 4-20 mA / 0-10 V outlet to monitor the position
• Valve suitable for carrying fluids that are clean and free of suspended particles.
The VKR DUAL BLOCK®valve combines
high reliability and safety aspects
typical of VKD full bore ball valves
with the new flow adjustment function
with typical linear curve that meets
the most stringent needs typical of
industrial applications.

In addition to the manually actuated
version, VKR is also available in
electrically actuated VKR/CE
configuration. Actuators are firmly
connected to the valve by the special
FIP Power Quick modules fully made
of PP-GR technopolymer. VKR/CE are
constructed with actuators meeting
current regulations and selected by
FIP according to their quality and
reliability requirements. The eciency
of these valves, tested according to
the company’s quality standards,
is guaranteed by the expertise and
know-how that FIP dedicates to
manufacturing its products.

1 Electric modulating actuator
constructed according to FIP
specifications; with plastic shell
and standard emergency override.
Available with voltages from 12
to 240V with 4-20mA and 0-10V
input.
2 High surface finish stem with
double O-Ring. The double
connection key system guarantees
solid and reliable actuator torque
transmission to the ball.
3 Easy to install PowerQuick module
for pneumatic or electric actuator
fully made of highly robust
technopolymer.
4 The patented ball design provides
linear flow regulation throughout
its range of operation even when
the valve is open just a few
degrees and guarantees minimum
pressure drops.
5 Patented DUAL BLOCK® system:
prevents union nuts from loosening
even under extreme operating
conditions: e.g. vibration or thermal
expansion.

TECHNICAL DATA

PRESSURE DROP GRAPH
RELATIVE FLOW
COEFFICIENT
The relative flow coecient is the flow
rate through the valve as a function of
the degree of valve opening.
X axis: Opening percentage of the ball
Y axis: Relative flow coecient
KV100 FLOW
COEFFICIENT
The Kv100 flow coecient is the Q flow
of litres per minute of water at a
temperature of 20°C that will generate
∆p= 1 bar pressure drop at a certain
valve position.
The Kv100 values shown in the table are
calculated with the valve completely
open.
