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

A pressure relief valve with DN15 nominal diameter, nominal pressure is 1.6 MPa. The pressure reducing valve automatically opens at a set pressure and provides proportional and slow pressure relief.

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: Does a pressure relief valve reduce flow?

Yes, the purpose of a pressure relief valve is to control or limit surges of pressure within pipelines, acting as protection for the system, and defending against instrument or equipment failure. But this only occurs when pressure exceeds the set pressure. During normal operation, pressures should not exceed the set level, and the relief valve remains closed.
