UPSTREAM PRESSURE REGULATING VALVE – SERIES MIC-800
The MicroSet Series 800 upstream Pressure regulating valve is a throttling pressure control device that opens and closes to ensure the upstream pressure does not rise above a predetermined pressure. The need for constant pressure and control of the media is the most essential part of various process industries size fertilizers, petrochemicals, Refineries, Pharmaceutical Chemicals & food processing Plants.

DESIGN FEATURES :
Glandless Construction: - Where positive Zero gland packing is required, the design scores
over conventional solutions such as bellow seals etc. as the gland itself is eliminated.
Wide range of body sizes and trim sizes to satisfy varied flow requirements.
Tight sensitively and stability of controlled pressure.
Provides excellent tight shut off capability over long working life.
Compact design with minimum number of moving parts.
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.
PRINCIPLE OF OPERATION
The upstream pressure is registered under the diaphragm opposing the spring when the upstream
pressure reaches the set point, the spring is compressed allowing the valve plug to open and relieve
SELECTION CRITERIA :
Familiarize yourself with the application consideration as they apply to your control
Inlet pressure setting and maximum allowable pressure buildup over the setting.
Normal and maximum inlet pressure.
Minimum, normal, and maximum flow rates.
Name, temperature and specific gravity of controlled fluid.
Inlet and outlet pipe size.
Environmental considerations, such as noise level, corrosion, temperature extremes, etc.
Special capabilities such as gauges, test connections, etc.
For final and optimum selection, contact MicroSet sales office / factory who will assist you in
Selecting the type and size that best suits your need.
