This compact modular design is manufactured from 316L stainless steel or aluminium and is supplied with a pilot/valve seat assembly (patent pending). The Model HIPEX series is SIL 3 third party certified to IEC 61508 Parts 1 & 2.
Available in1/2", 1" & 2" with various port sizes ranging from1/4", 3/8" & 1/2" NPT sizes
(1/2" HIPEX Valve) and 3/4" & 1" NPT sizes (1" HIPEX Valve). The 2" HIPEX Valve is supplied
with 2" or 11/2" NPT port sizes. The valve operates on a 1:1 pilot pressure to valve pressure ratio at pressures between 2 and 10 bar g.
This specially designed valve is able to perform various functions:-
Partial Close Testing Function
When the pilot pressure falls below the main valve inlet pressure, the valve quickly exhausts the excess pressure until both the valve and pilot pressures are again equal, then the exhaust port closes.
Pressure Relief Function
If the main valve inlet pressure increases above the pilot pressure, the valve automatically exhausts the excess valve and the excess valve actuator pressure.
Applications include activation of control valves used in chemical, petrochemical, oil and gas, pharmaceutical and food processing markets. This range has been designed and tested at Bifold and supplied for use with the majority of positioner/valve actuator manufacturers.
