Note: This pressure relief valve cannot be used for drinking water.

Buy a pilot operated pressure relief valve with DN100 nominal diameter, nominal pressure is 16 MPa, which is made of ductile iron QT450 makes it more durable. The water pressure reducing valve is widely used in high-rise buildings, areas with excessive water pressure in urban water supply networks, mines and gas pipelines, etc.

Features

Pilot-operated valves for limiting a system pressure
Operation using proportional solenoid
Maximum pressure limitation
Valve and control electronics from a single source
Little manufacturing tolerance of the command value
Pressure characteristic curve

Installation

Notes

It is recommended to install an exhaust valve on the top of the riser to make the pressure reducing valve work more smoothly.
Before installing the pressure relief valve, check the valve for unusual items and be sure to flush the pipeline.
Installation method: Horizontal or vertical installation, single valve set.

Pressure Relief Valve Application

Tips: What are the advantages of a pilot-operated pressure relief valve?

Like other pressure relief valves (PRV), pilot-operated relief valves (PORV) are used for emergency relief during overpressure events (e.g., a tank gets too hot and the expanding fluid increases the pressure to dangerous levels).

The smaller package on the larger pipe sizes.
More options for control.
Seals more tightly as the system pressure approaches but does not reach set pressure.
The control pilot can be mounted remotely.
Some designs allow for changes in orifice size within the main valve.
The PORV can be used in engines.
Higher Operating-to-Set Pressure ratio.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
