Pietro Fiorentini  water pressure regulator/ Pietro Fiorentini shut-off pressure regulator valve /pressure maintaining valve



Pietro Fiorentini Pressure Relief Valves / Pietro Fiorentini Cut Valves / Regulators Pietro Fiorentini specializes in research and innovative products, continuously improving the quality of service, products are used for gas filtration, separation, dehydration, heating, metering and so on.



Pilot gas regulator aperflux 101:

Aperflux 101 is a high pressure pilot pilot pressure regulator. Aperflux is "not open" regulator that it will be in the following conditions:
• if the main diaphragm fails;
• If the pilot diaphragm / failure;
• If the pilot seat valve fails;
• If there is no feed test circuit.
These regulators are suitable for use with pre-filtered non-corrosive gases.



Pilot gas regulator aperflux 851:

851 aperflux medium and high pressure applications pilot control pressure regulator.
Aperflux 851 usually does not open the regulator, will be specific under the following conditions:
• if the main diaphragm fails;
• If there is no feed test circuit.
This regulator is suitable for pre-filtered, non-corrosive gases.

Natural gas valves:

Flange stock ball valve cut-off device suitable for use in natural gas distribution networks and services, liquid sealing, low pressure to reduce performance requirements.
The main features of these valves are:
• Float
• The foam is sealed in the closed position of the valve
• Low pressure drop
• Can be installed in both directions
• highly reliable
• Establish standard ANSI / ASME B16.10 ANSI / ASME b16.25, British Standard BS 5351
• Pressure rating: 150 - 300 - 600
• Size: 1/2 "3"
• Full and reduced holes
• Connection: RF

Natural gas valve BF 31:

Bf31 butterfly valve ordinary low pressure gas pipeline closure device.
They can also be used to intercept liquid seals, low pressure losses in the flow direction and compact structural requirements.
The characteristics of these valves are as follows:
• Inner seal valve
• Low pressure loss
• Can be rotated by the butterfly through 360 ° so that self-cleaning does not remove the valve body from the pipe
• Not a permanent pipe, as a flow direction is possible
• Butterfly valve seals
• chrome-plated spherical face longer life with internal seal and low control torque
• highly reliable
• Establish a unified standard 9245
• Face-to-face according to UNI 9245 and ISO 5752, MSS SP 67, BS 5155-74

Gas filter:


The gas filter and the DIN 3386 standard are designed for use with all types of natural gas, liquefied petroleum gas or non-corrosive gases. These filters are widely used to protect control devices, pressure regulators, meters and systems that require high filtration. High filtration capacity of the ink cartridges and extensive surface allows the separation of dust and solid particles, reducing the maintenance time for the equipment to install downstream.
main feature:
Strong construction
• Effective filtering
• Easy to maintain
All filters are covered at the test points of the filter inlet and outlet.
• Flanging die. 10210 floor: the maximum allowable pressure: PS 2 working pressure 2 bar
• Thread Series 106 ...: Maximum allowable pressure: PS 6 working pressure 6 bar
• Flange Series 106 ... / F: Maximum permissible pressure: PS 6 working pressure 6 bar
• Thread series connection: uni-iso 7/1
