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

Reliable pressure relief valve with DN20 nominal diameter for sale online, pressure deducing valve comes with nominal pressure 1.6 MPa. The adjustable pressure relief valve is used to limit or control the pressure in a system.

Features

• The pressure relief valve accurately controls the dynamic and static pressure, and does not fluctuate due to changes in upstream pressure.
• Its dual piston has a large flow rate (about 3 times that of common similar valves) and low flow noise. This valve is made of stainless steel, which is high-strength and environmentally friendly.
• The internal structure of the spring loaded pressure relief valve is compact and reasonable, saving a lot of installation space.
• The installation environment requirements are simple, the pressure adjustment is wide, and the optimal water supply pressure can be adjusted on site without professional operation.

Installation Precautions

1. For easy operation and maintenance, the pressure relief valve is generally installed upright on a horizontal pipe.
2. During installation, care should be taken to ensure that the flow direction of the medium in the pipeline is consistent with the direction of the arrow shown on the valve.
3. In order to prevent the valve from being blocked by debris, a filter should be installed at the front end of the pressure relief valve.
4. In situations where the supply cannot be interrupted, a bypass valve should be provided or a dual-circuit method should be used, one for use and one for backup.
5. When passing water for the first time, care should be taken to exhaust the air in the pipeline to avoid false pressure, to protect the pressure gauge and obtain the correct pressure.

Pressure Relief Valve Applications

Tips: What is a pressure relief valve?

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment and relies on the energy of the medium itself to keep the outlet pressure automatically stable. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of decompression. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the post-valve pressure with the spring force, so that the post-valve pressure remains constant within a certain error range.
