INTAKE VALVE

The check receiving valve is used for the intake of petroleum products through the intake pipeline and automatic prevention of backflow in pumping units at the ends of the suction medium pipelines.

Receiving type valves

The receiving valve is also necessary for holding oil products in these pipelines of underground and ground vertical tanks (industrial tanks) for storing oil (oil products).

KP intake valves can be made with a crown (for cleaning the bottom of tanks or industrial tanks of gas stations or oil depots and oil storage facilities), or with a intake (for pumping oil and petroleum products from tanks or industrial tanks of gas stations and oil depots).

Technical information

These valves are installed in front of the pumping equipment at the end of the vertical suction line. On the pipeline, this valve is installed with a grid at the bottom.

Sealing

To ensure electrical insulation of the flanges from each other, gaskets made of paronite PMB (4 mm) are provided, a coating made of bakelite varnish protects against moisture saturation. Such gaskets can also be made of vinyl plastic (or fluoropolymer). The tightening pins are enclosed in split fluoroplast bushings.

Rebar flanges

The main applicable flange standards are ASME, ANSI, EN, DIN. All metal products are regulated by special documents, which contain all the basic information about the elements: dimensions, shape, types, types of connecting surface, pressure classes, materials and manufacturing methods.

Mounting elements

Fasteners (stud, nut, washer) are used according to DIN EN ISO standards, depending on the load, climatic and temperature conditions of the pipeline valves.

Paint Job

Special types of primers and paints are used for anti-corrosion protection and long-term protection of metal in temperate and cold climates.
