Product use

The relief valve to adjust and control the main valve outlet pressure, the main valve outlet pressure does not change due to the inlet pressure changing, nor because of the change of the main valve outlet flow to change its outlet pressure, can be used for drinking water, fire fighting system and industrial system.

General principle is to use pressure reducing valve control valve open-close part of the opening in the body to adjust the flow of the medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, and the valve body or valve after the injection of cooling water, reduce the temperature of medium, the valve is called desuperheating valve to relieve stress. The characteristics of the valve, is under the condition of the inlet pressure changing, keep exports to the pressure and temperature in a certain range

Pressure reducing valve can be divided into the form of the structure diaphragm, diaphragm spring, piston, lever and bellows type; According to the seat number can be artificial single-seat and two-seater; According to the position of the disc can be divided into different function type and reaction type.

Pressure reducing valve installation and maintenance should be paid attention to the following items:

In order to convenient operation and maintenance, the valve usually upright installation in horizontal pipe runs.

When installation should pay attention to the flow direction of the medium inside the pipeline and valve Hugh is shown in the same direction of the arrow.

In order to prevent the overpressure valve after pressure, should from the valve outlet of no less than 4 m to install a pressure reducing valve.
