Introduction
The Flowrox PV, PVE and PVE/S heavy duty pinch valves
are designed for shut-off and control applications involving
abrasive or corrosive slurries, powders or granular substances.
3.1
Intended use
Open type PV.
The open body is available in diameters starting from 80mm.
The open body construction is designed for applications with:
•
Low pressures
•
Low temperatures
•
Non-hazardous media
The open body construction is light and simple, which makes
it easy to access for service. The open body also tolerates
misalignment and vibration.
Enclosed type PVE.
The valve sleeve is covered by the body housing and thus
protected from the environmental impacts and sunlight.
•
Body construction prevents leakage of flowing media to
the environment
•
The valve body can be equipped with a gauge indicating
pressure changes inside the body

PVE/S
PVE/S includes extra stem and body seals to provide a
secondary containment of the fluid in the valve and to
prevent leakage to the outside environment.
