Pio-Safe®
Pilot Operated Safety Relief Valve
Introduction:
Piloting the Precision control ....... The Brightech Way
Pio-Safe , a Unique & Innovative Pilot Operated Pressure / Safety Relief Valve are engineered to facilitate today’s needs of an industrial requirements of high performance , high capacity and zero leak for system overpressure protection .
Product description:
Pio-Safe , BTS-5000 Series , is a self-actuating , Angle discharge , Non-Flowing Snap [ Pop ] type / Modulating type Pilot operated , Semi-Full Nozzle Integrally Cast , Flanged end Pressure Relief Valve
Operating Principle:
Comming Soon.....
Features & Benefit :
- The System operating pressure can be much closer as compared to spring loaded valve , allowing the process to be maintained at close tolerance without valve leaking , resulting max. process out put.
- full lift capacity is maintain at set pressure against high level of back pressure during popping action unlike spring loaded which would req. either differential setting or the addition of expensive & fragile bellows.
- Non-Flowing pilots remove the risk of freezing due to pressure drop in the flowing medium.
- Unique modulating pilot operated design for liquid service minimize product loss and eliminates vibration and assure trouble free operation.
- Minimize maintenance cost due to replaceable soft seat design , ensure repeatable leak tight seating & re-seating.
- Easily adjustable set pressure is accurate and
- External adjustable blow-down , reduces system down time.
- Metal to Metal sealing provided for high temperature.
- Pilot Operated Valves are Less in weight & compact in design compared to Spring loaded.
- Available in verity of material and end connection type.
Pio-Safe , Pilot Operated Pressure relief valve design advantage. :
- Reduce Installation & Maintenance cost
- Minimal Product Loss
- Long Service Life
- Higher System Out put
- Top entry main valve for easy access
- Reduce environmental pollution
- Reduce system down time
Application:
- Precision pressure control in oil & gas industries , onshore , off shore
- Chemical Plant / Cryogenic service
- Air, Gas, Vapour, Stem & Liquid service
