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 is difference between pressure relief valve and pilot-operated pressure relief valve?

Process pressure exerts an opposing force on the disc. When the process pressure force on the disc overcomes the opposing spring force, the disc lifts and the valve begins to relieve pressure. In contrast, a pilot operated valve uses process pressure to keep the valve closed until set pressure is reached.

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.
