INTRODUCTION TO DEVICE
2.1 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
2.2 Construction of device
Flowrox valves are made of three main components:
•
flanged valve sleeve
•
valve body, either open PV or enclosed PVE
•
actuator and actuator control components, if applicable
The valve sleeve is the only part of the valve which is in contact with the medium flowing
in the pipeline.
All valve bodies are flange ended. The standard flange drillings can be made to meet all
standards (e.g. DIN, ANSI, BS, AS, JIS).
The face to face dimensions of Flowrox valves are according to ANSI/ISA 75.10.02:
•
165 mm for valves DN25…DN65
•
2 ½ times the nominal diameter for valves DN80 and bigger
