The Ashcroft® Type 1490 low pressure diaphragm gauge is designed to measure
pressure from 10 in. H2O to 15 psi, both positive and negative pressures. This
gauge uses a very sensitive diaphragm capsule to measure low pressure and
vacuum.
The gauge is specifically designed for use whenever the pressure
medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and
RTV silicone. The polysulfone case is suitable for intermittent or continuous
service on natural gas provided a .013 throttle plug is installed in the socket.
Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air
compressors, air filters, gas burners, gas measurement, vacuum ovens, suction
regulators and respirators.

Available Sizes
Regular: 3/8", 1/2", 3/4", and 1"

Diaphragm: 4" Molded, roll-out polyester fabric reinforced Buna-N with integral relief seat and case flange seal
Vent and Valve: Precision-fit polypropylene valve and seat, threaded 3/4" or 1" NPT
Adjustment Screw: ABS cycolac
Closing Cap: ABS cycolac with internal relief valve stop and a hole for available tamper seal wire
Corrosion Protection: Chromate converted castings, topcoat enamel,optional E-coat
Internal Relief Valve: Set to relieve at 7" w.c. - 10" w.c. above normal outlet pressure setting of 7" w.c.

For use on other compatible gases, flow capacities must be adjusted using the following correction factors:
Type Gas Sp Grav Corr Factor
Air 1.0 0.77
Propane 1.53 0.63
Propane-air 1.2 0.71
Nitrogen 0.97 0.79
Dry CO2 1.52 0.63

For other non-corrosive gases, the Correction Factor is equal to: √0.6/Specific Gravity

Mounting Positions
These are multi-poised regulators, designed to that they can be mounted in any piping orientation.

Available Models:
30051-1XS: 1/2” NPT
30052-2XS: 3/4” NPT
30053-3XS: 1” NPT

Pietro Fiorentini's Governor line of gas regulators are designed to comply with the latest CSA and International standards for regulators suitable for indoor or outdoor installations with no modifications.

The Governor family of regulators are ideal for all burner installations and for low pressure gas distribution systems. The materials and soft parts used in the construction of the Governor regulators makes them suitable for use with natural gas, LPG, Propane air and all other non corrosive gases.

All the Governor regulators are equipped with balanced valve design for high outlet pressure accuracy regardless of any inlet pressure variation. The double diaphragm provides added security in case of primary diaphragm failure. The integral vent limiter eliminates the need for costly piping for indoor installations and complies with CSA guidelines. The number of regulator options sometimes eliminates the need for separate units and significantly reduced installation cost.
